LESS ENERGY. FEWER EMISSIONS. MORE COMFORT.

Modern technology and the environment

Thirty-year development and production of condensing equipment, focused from the very beginning only on the best solutions, has brought the products

to an excellent technical level. Nowadays, the trend is not only the technologies themselves but top technologies essentially respecting our

environment.

The producer adheres to the Ecoefficience motto which actually means maximum efficiency, the lowest possible energy consumption and the amount of

harmful emissions below the limit with the above-standard user comfort. The basis for success is the perfect design of Geminox condensing boiler

equipped with the latest Siemens LMS control unit. The basic integrated control system has capabilities

for easy expansion by alternative energy sources such as solar collectors, heat pumps etc.

The unique technical solution ensures these 5 stages of fuel savings:

The first stage consists of condensation when such part of heat is utilized which escapes into a chimney in conventional boilers.

This additionally gained heat is used to preheat return water from the central heating.

The second stage is optimization of the combustion process in the entire power range of the boiler. Due to the constant air / gas ratio the

patented circular burner with fuel (natural gas or propane) and air pre-mixing ensures maximum combustion efficiency with a minimum

content of harmful emissions.

The third stage is adaptable equithermal regulation integrated in Siemens LMS boiler control unit which prevents unnecessary exposure

of walls of the building to cold and optimizes thermal comfort in the building and increases the efficiency of the entire heating system.

Connection of solar collectors offers above-standard savings. The LMS control unit is prepared for easy expansion of the heating system

by other alternative sources.

The fourth stage is the intelligent speed control of a low-energy circulating pump of Class A. This feature significantly reduces the return

water temperature during transition periods and thereby dramatically expands the zone of the use of condensation. Even the overall

reduction in energy consumption is not insignificant.

The fifth, the most important stage is represented by a wide linear modulation allowing uniform heating of the building without unnecessary

cycling of the boiler. It is no secret that in 3/4 of the heating season 15-50 % of the nominal power of the boiler is fully sufficient. All

conventional boilers, in which the power cannot be reduced to the mentioned values while maintaining guaranteed efficiency, thus become

very uneconomical for 3/4 of the heating season. One of the strongest benefits of THRs boilers is the ability to operate with maximum

efficiency and without cycling even during the most common outdoor temperatures in the range of 5-15 °C. This advantage is most evident

in modern family houses. Today's new buildings usually have a heat loss around 10 kW. According to the above stated and practically-tested

principles it is therefore necessary for the normal operation of such a building to reach the starting power of the boiler lower than 3 kW. If

this parameter is not satisfied and the boiler is operated outside its operating range, the so-called cycling begins. Standard boilers

with the starting power of 6-8 kW undergo such switching off and on up to 40,000 times per year. This number seems very untrustworthy but

after a conversion to heating days in a year it means one start of the boiler every 10 minutes. However, we know from our experience that

even minute intervals are no exception. The properly selected Geminox THRs condensing boiler will not make more than 4,000 starts per

year. It must be clear even to an amateur what conclusion can be drawn from these data.

A unique feature of THRs condensing boilers is the ability to change their output range. The increase or decrease of the boiler output range

can be achieved by substituting the affordable burner and reprogramming the operating software. This innovative philosophy allows you

to always optimally operate THRs condensing boilers. They do not force investors to make compromise purchases reflecting their future

plans related to the increase in demands for heat production (extensions, heated swimming pools, indoor gardens, etc.). This achieves the

standardized utilization degree within the range of 106-109% (PCI) in the whole modulated range. The result is 25 to 40% fuel savings

compared to conventional boilers.

By its focus, Procom Bohemia s.r.o., the exclusive importer of Geminox condensing

boilers, supports only environmentally friendly equipment. It also acts

environmentally friendly in its daily activities which is proven by the Environmental

Management System Certificate ISO 14001:2005 for selling and servicing the eco-

friendly thermal equipment. This system significantly helps to reduce the impact of

company activities on the environment and also brings a significant reduction in

operating costs.

Procom Bohemia s.r.o. also strives to maintain a high level of services in the sale and

service of eco-friendly thermal equipment and is therefore controlled by the Quality

Management System according to ISO 9001:2009.


Condensing boilers THRs



Designed even for the most demanding applications

Already the fourth generation of condensing boilers with THRs (Trés Haut Rendement - very high efficiency) designation with the Siemens LMS control

unit is designed for places where achieving the ideal thermal comfort with minimum operating costs is a clear priority.

High quality design elements of boilers, such as the patented stainless steel burner, large stainless steel heat exchanger or stainless steel hot water tank, are

complemented with the state-of-the-art Siemens LMS control unit. In addition to standard combustion and safety functions it controls one or more heating

circuits including the hot water production. The basic equipment of the automatic system includes also the functions of solar heating, possibly a

combination with alternative sources or cascade management.

A wide range of power options is complemented with a double-circuit wiring or various combinations with water heating. The offer must cover the wishes

of even the most demanding customers.

Grundfos UPS 15-50 pump and a three-way valve with ESBE servo-drive (Kv = 4) are integrated during production in the THRs DC boiler and are

parts of the hydraulic connection of the second (mixed) heating circuit designed for floor heating (see diagram T2).

The design process of the mixed heating circuit (MTO): With the design temperature difference (according to ČSN EN 1264 we design ∆T = 5 °C

for floor heating) and the given heat loss of the floor heating circuit the required flow is determined for MTO. The pressure drop of the mixing valve (Kv = 4) is

subtracted from the flow.

The subtraction of the heat exchanger pressure drop is performed by increasing the temperature of boiler water by 5 °C compared to MTO. Therefore, we subtract the heat exchanger pressure drop at a lower flow rate but at the same power! This elevation difference is preset by the boiler control.

Example: If we design MTO with a gradient of ∆T = 5 °C, then the pressure drop of the boiler heat exchanger (Kv =3.6) is subtracted at ∆T = 10 °C.

It is necessary for the MTO design that the required overpressure remains to cover the pressure drop of the system. If the MTO pump will not cover the sum of

pressure drops, it is necessary to design the pump with higher performance. It is not possible to replace the MTO pump in a double-circuit THRs DC boiler. It

follows that in this case you cannot use the double-circuit THRs DC boiler. So we choose the hydraulic connection according to 2B and 2C diagrams.

Examples MTO limit performances: 7 kW at ∆T 5°C, approx. 17.5 kPa remains for MTO. 12 kW at ∆T 8°C, approx. 17.5 kPa remains for MTO.

The control system of THRs condensing boilers

In recent years we have seen a sharp increase in requirements for the

systems intended to control condensing boilers. These requirements have

already exceeded the basic requirements for safe operation of gas

appliances and combustion process control. Nowadays, the equithermal

control of the heating circuit and HW production are a common standard of

the burner automatic system of the boiler. But even such a concept of the

control board is not able to systematically work in technologies with

several heating circuits, in boiler cascades or in multivalent systems. Nor is

it able to provide constant monitoring of the entire application using remote

monitoring via the internet connection.

Siemens, the supplier of the entire control system of condensing

boilers, combined its long-time experience with the latest results

of the work of several development teams and launched a top-

class concept. The resulting product is the LMS14 burner

automatic system. However, in its basic design it must not

unnecessarily increase the price of the boiler. Therefore, it only

has inputs and outputs for above-standard control of one

equithermal circuit and HW production. However, it also offers

the possibility of separate control of the circulating pump and

addition of sensors and control of HW solar heating. This feature

gives Geminox boilers a competitive advantage. The users of this

unique technology are also allowed to select from several types

of room units, economical or highly comfortable, and from their

wireless models.

In the case of larger technologies (e.g. several heating circuits, cascades)

the LMS burner automatic system has a absolutely unique feature. It

integrates almost all functions of the Siemens RVS control system of

Albatros2 series.

After connecting the extension modules (they complement inputs and

outputs) to the LMS automatics we obtain the same opportunities of

control of resources (solid fuel boiler, solar collectors) and appliances

(up to three mixed heating circuits, swimming pool, external appliances,

etc.). The extension modules are

offered as accessories, in a version for installation in the boiler (Clip-in)

and in a version for installation into the box (for example at a mixed

heating circuit). At first glance the unnecessary duplication of features

always offers the ideal combination of the system set with regard to the

price, building layout, the length of cable routes and many other

criteria. As an example, the following two typical cascade applications

can be mentioned. The first is a simple "legislative" cascade of 2 x

49kW with HW production and one mixed circuit (Fig. 22.1). The

additional RVS regulation can be left out here and we can take

advantage of the properties of the boiler automatic system. Savings in

this application reach tens of hundreds of dollars. The second case can

be a block of flats where after disconnecting from the central heating

system the distributor with heating circuits remains in the basement and

the boilers cascade will be installed in the attic (Fig. 22.2). Here, from

the perspective of price, labour-intensiveness and cabling it will be

more convenient to use the RVS regulator to control the boiler room

and connect the boilers only by a two-wire communication cable.

The quality of the control system is a prerequisite for correct

and optimal functioning of any heating system.

With the increasing complexity the work of service technicians is

still more and more important. Siemens took this into account when

creating the system. Due to the unification of the control concept,

menu structure, PC tools and sharing of functional blocks it is now

possible to ensure 100% transfer of gained knowledge and equipment

of technicians between equithermal regulators, boiler automatic

systems and heat pumps, for example. In order to diagnose problems

the system has detailed information on the conditions of individual

parts of the technology, showing actual and desired temperatures.

For more demanding users that require remote monitoring and convenient

adjustment of parameters via PC, mobile phones or smart TV and in order

to completely improve the service operability it is beneficial to

complement the boiler automatic system with Webserver OZW672 for

Internet communication.

Boiler control unit LMS14

LMS14 LMS14 boiler automatic system is a digital control unit designed for gas condensing boilers with a

modulated burner. In terms of priorities, its main task is to ensure the safe operation of a gas appliance

in all circumstances and optimum control of the combustion process.

Its biggest advantage, compared to the competing products, is a possible extension by a group of

accessories enabling the use of all its features. To connect peripherals the unit has an internal BSB

bus (Boiler System Bus). It is a firm connection using a two-wire, respectively three-wire cable.

Two neighbouring devices communicate over distances up to 200 m with a limit of the total length

of wiring to 400 m. If there is no pre-prepared wiring, you can connect the room devices and

outdoor sensor by using radio communication at 868 MHz. The distance for radio communication

connection cannot be unambiguously determined as it depends on the structure of the building.

Generally, the distance of 30 m is stated, or even three walls/two floors. In structures with difficult

radio signal propagation or to extend the reach the product range also includes a signal amplifier.

The second communication bus which serves to connect the additional RVS regulation or other

automatic systems is LPB (Local Process Bus). It is used in larger systems of resources and

appliances. This option is gained automatically after connecting the communication Clip-in

module OCI345.

Basic accessories

Outdoor sensor QAC34 In most cases, the system of equithermal control system is chosen for heating the building, with or

without the influence of the interior temperature. The equithermal control system of Geminox

condensing boilers ensures perfect thermal comfort throughout the building, significantly reducing

energy consumption and extending the equipment life. The condition of use of the system is to install

the outdoor sensor. Information about the outside temperature provides also some security features

such as protection of the heating system from local freezing. The sensor is connected to the control

unit by a two-wire cable in a maximum distance of 120 m. Due to its timeless design it does not

disturb the appearance of the facade.

Integrated control panel AVS37.294 The basic user interface of THRs boilers is the control panel AVS37.294 which allows

access to all parameters. These are clearly arranged to three service levels according to the

operator authorization. The system diagnostic has information on actual and desired

temperatures and operating conditions of each component of the technology. The control

panel is integrated into the design of the Geminox boiler and is connected to the control

unit by a special flat cable.

Boiler accessories for BSB bus connection

Room unit QAA75.611 Comfortable room unit with a backlit display (three-wire connection as a condition). It complements

the control strategies with the equithermal regulation with the influence of room temperature or

purely space control. It is equipped with controls for quick change of the desired comfortable

temperature, operating mode of the heating circuit, switching hot water on/off and with a presence

button. There is also an information button to display temperatures and operating conditions of

equipment. The device allows full access to all control parameters including time programmes

adjustment as in the integrated control panel of THRs boilers. It can be assigned to a specific heating

circuit or it can control all circuits together.

Room unit QAA55.110 A basic room unit with a two-wire connection. It complements the control strategies with the

equithermal regulation with the influence of room temperature or purely space control.

It is equipped with controls for correction of the desired comfortable temperature, switching the

operating mode of the heating circuit, switching hot water on/off and with a presence button. The

unit is assigned to a particular heating circuit and is complemented by the possibility of operation

deadlock for the installation in public areas.

Extension clip-in module AGU2.550 The basic function of the expansion module is to complement the terminal box of the boiler automatic system

with other two sensor inputs, one H input (potential-free contact/0-10V) and three relay outputs to

configure additional functions. A typical application is the control of the mixed heating circuit as

in THRs DC boilers. However, the possibilities of use of inputs/outputs are much broader. The

structural design is adapted to the installation directly in the boiler. The electronics cabinet of

Geminox boilers has prepared positions for a maximum number of three modules. A multiple flat

cable with keyed connectors is used for connection.

Extension module AVS75.390 In terms of features and use, this module is identical with the clip-in module AGU2.550.

The main difference is in the type of construction. It is designed for the installation outside

the boiler into the junction box near the technology (e.g. mixing heating circuit, wood

boilers). The connection cable can be extended up to 200 m.

PWM clip-in module AGU2.551 A built-in module is designed for connecting the boiler with the master control. It contains two PWM

signal converters to 0-10 V signal and two potential-free relays. The master control can get

information about the fan speed (current boiler output) and speed of the boiler pump using the

standard 0-10 V signal. The outputs of the boiler operation and failure can be connected to the relay.

The module is powered from the BSB bus and does not limit the number of connectable extension

modules AGU2.550 (AVS75.390).



Wireless accessories for THRs boiler

Radio transmitter/receiver AVS71.390 The basic prerequisite for the use of wireless peripheral devices with the boiler automatic

system is the connection of the radio module. RF module AVS71.390 is the basic model

with an integrated flat cable (1 m) for connection to a specific connector fitted on the automatic

system board. This fixed connection may limit the choice of location. The module must not be fitted

to the interior of the boiler. Therefore, we prefer to use the module AVS71.393 described below.

Radio transmitter/receiver AVS71.393 Also this RF module extends the features of the control board of the possibility to connect

radio peripherals. Unlike the AVS71.390 module it is connected by a three-wire cable to the

BSB bus and its installation is therefore possible to a distance of 200 m from the boiler. This

allows us to choose an optimal location for installation with the best reception.

Room units QAA78.610 and QAA58.110 Both radio room units are identical copies of wire models QAA75.611 and QAA55.110. They

allow the use of all their functions without specific demands for placement (while respecting

the basic installation rules). The only difference is the absence of the backlight. The units

communicate bidirectionally with the possibility of testing the quality of signal transmission.

They are powered by AA batteries with a life expectancy of up to three years.

Outdoor temperature transmitter AVS13.399 The device is installed in the interior and has an outdoor sensor QAC34 placed in the same position

on the outside of the perimeter wall connected by a two-wire cable. It is important for the easy

replacement of batteries and the battery capacity is not adversely affected by low ambient

temperature. The outdoor temperature transmitter is powered by AAA batteries with a life

expectancy of up to three years. When installing the outdoor sensor QAC34 it is necessary to respect

the basic installation rules.

RF signal repeater AVS14.390 In case of installation in buildings with very poor radio signal propagation or to extend the reach the

system can be complemented by the AVS14.390 repeater. The transmitting power is identical with

other elements and allows the range to be doubled. It is powered by a drawer adapter that is included.


LPB communication

LPB clip-in module OCI345 Communication module is used to connect multiple boilers in cascades and/or to make connection

with RVS and RVD regulators. The module is equipped with a special connector and does not limit

the number of connected extension clip-in modules AGU2.550 (AVS75.390).

The maximum number of devices on the LPB bus is 16.

Temperature sensors

Contact sensor QAD36

It is the most common sensor for sensing heating water temperature. Its advantage is easy

installation on a pipe with a diameter of 15-140 mm, without using the heat sink.

The sensor is equipped with a sensing element NTC 10k Ohm. It is connected to the control unit

by a two-wire cable with a maximum distance of 120 m.

The temperature range is -30 to 125 °C.

Heat sink sensor QAZ36 The sensor is designed to sense the temperature in the HW tank or in the storage tank.

If the pipe is equipped with a heat sink the sensor can be also used for measuring the temperature of

heating water. Its advantage is low price. It comes with an integrated cable, 6 m in length. It is

connected to the control unit by a two-wire cable with a maximum distance of 120 m. The

temperature range is 0 to 95 °C.

Heat sink solar sensor QAZ36.481 It is a special version of the heat sink sensor NTC 10k Ohm with a higher temperature range of -30 to

200 °C, with a 2m integrated cable with silicone insulation. It is primarily intended to measure the

temperature of solar collectors but its another very good use is also measuring the temperature of

embedded fireplace inserts with a heat exchanger.

It is connected to the control unit by a two-wire cable with a maximum distance of 120 m.



Web server

Remote control of the heating system via the Internet

Ideal tool for easy control and operation of the boiler control system from anywhere in the world. In case of a fault an alarm is sent via email or SMS to

predefined recipients. By installing the Web server the user obtains the possibility to be connected to the system of comprehensive maintenance services

including remote monitoring by the central control centre. Providing the equipment importer with the access to the web server extends the boiler warranty

by 12 months.

Webserver OZW672 Web server OZW672 offers its users the ability to remotely control and receive alarm messages via

the Internet using a PC or smartphone. Commissioning and operation are very simple. Since the web

server is directly integrated into the OZW672, all you need is the Internet connection in the house.

Therefore, the use of the web server requires no additional operating costs. If OZW672 is connected

to the boiler control unit, all setting changes are automatically taken over and are immediately

available on-line. For easy and fast commissioning of the device you have a starting page available

with the most important data points.

Recommended connection diagrams Considering a huge number of combinations of sources and equipment connections that can be controlled by the LMS boiler automatic system in

combination with clip-in modules and the RVS regulator system the following list of recommended connections was developed. The aim was not to

describe all possibilities but the most common technologies. Those were chosen with regard to the typical customer requirements, experience from

implemented installations and long life.

It is always the connection of the gas boiler or boiler cascade and the heating circuit. If the basic connection allows it, the diagram is always completed with

an alternative for connecting HW, additional heating circuits, sources (solar, fireplace), swimming pool or external appliances.

Our goal was to create the basis for a simple design of the system in a recommended hydraulic connection. It contains a basic description and specification

of necessary components to order. There are also necessary basic information for wiring and placement of sensors.

appliances with a heat demand signal 0-10 V (optionally ON / OFF), with a possible extension of HW heating in an indirectly heated container by

a switching valve from one boiler (absolute production priority). This connection is suitable for the building

with a low HW consumption with regard to the heat loss of the building (for example, office buildings or schools without a canteen).

Connection diagram T9 The connection of the THRs condensing boiler in a trivalent system with one mixed heating circuit, solid fuel boiler, HW solar heating and

heating solar support. The connection demonstrates maximum options of the LMS boiler automatic system control unit

by using three extension modules without the need for additional RVS regulation. Used hydraulic connection allows

both an alternative and bivalent operation of heat sources. It saves the cost of control system but the "all of boilers" is demanding for wiring

implementation. It is always necessary to consider whether the T9 connection is better for the given installation.

Connection diagram T10 The connection of the THRs condensing boiler in a trivalent system with one to two heating circuits, solid fuel boiler, HW solar heating and heating solar

support. Any pool heating can be performed by solar heating, the main source or by the exhaust of the excess

heat of a solid fuel boiler. The connection exceeds maximal options of the LMS boiler automatic system control unit by using three extension module,

therefore the additional RVS regulation is used. Used hydraulic connection allows both alternative and bivalent operation of heat sources.
