5.2 RBC-CC163TLE2 ON/OFF Controller

Description

The on/off controller is a product that is capable of operating 16 indoor units from a singlelocation. The device consists of 16 individual on/off buttons, which allows any connectedunits to be enabled or disabled via a single button operation. It is also possible to enableor disable all of the connected units via single button operation.

Application

The device is ideally suited to locations where it may be necessary to remotely enable ordisable indoor units. An example of this would be a hotel reception desk, where thereceptionist may wish to enable a customers room air conditioning during the check-inprocess or disable it on the departure of a customer. Each of the on/off buttons has a labelfacility and again using the example of a hotel installation, the buttons could be labeledwith a room number. For larger installations up to 4 controllers could be installed on onenetwork, thus allowing 64 master indoor units to be controlled from one location.The device also has the facility for interfacing time clock control, remote switching, remoterun signal and remote fault indication from a set of auxiliary contacts.

Connections

The controller requires a 240 Volt single phase 3 Amp power supply, which connectsdirectly to the mains input terminals on the rear of the device.


36/72

36

The two-core network cable should be screened and have a minimum cross-sectional areaof 1.5mm for networks of up to 1000 meters. This should be increased to 2.5mm fornetworks of 1000 to 2000 meters total length. The network cable terminates at the U1/U3and U2/U4 connections on the rear of the device.

Terminals A1, A2 and A3 are used to remotely operate all of the connected indoor units.The indoor units can be enabled with a pulse voltage of 24 Volts applied for 0.5 secondsbetween terminals A1-A3 and disabled by applying the same voltage between terminalsA2-A3.

Terminals B1, B2 and B3 provide dry contact outputs for connection to other systems. Arelay contact will close between B3 and B1 indicating system operation and B3 and B2indicating a fault on any connected units.

Terminal CN02 can be used to connect a 7day timer (RBC-EXW21E) or alternatively theRBC-SMTI interface lead can be connected and used as a means of remote switching.

5.4 TCB-PCNT30TLE TCC Link Network Adaptor

Description

The device is intended for use on all the DI/SDI units other than the KRT HighWall, which is supplied with the adaptor built in. The device is designed to allowNetwork devices such as Central Controllers and BMS systems to be interfaced.

Application

The device consists of a small PCB, which should be installed within the indoorunit and would typically be used where the indoor unit/units will be interfaced with aCentral Controller or any other network device, such as a BMS system. One deviceis required for each indoor unit or group of indoor units. Where indoor units aregrouped together they will be assigned with one address on the central device andwill consequently all receive the same operational instructions.

Diagram


41/72

41

Connections

The device connects to the indoor unit PCB via socket CN50 and will provide two

terminal network connection designated U3 & U4.

Where multiple devices are to be installed it is necessary to set one unit with a100ohm termination resistance. This would normally be on the device connected tothe unit with the lowest network address. The resistance being set by SW01 bitbeing set to ON.

When the device/devices have been installed and a termination resistance appliedit is then necessary to apply a unique network and refrigerant line address to eachunit.

Addressing Procedure

The address setting is carried from a standard RBC-AMT21/31E remote controller.Where units do not have standard remote controllers installed, one should betemporarily attached in order to carry out the configuration process.

Accessing the Engineers configuration menu

Press Set CL & Check Simultaneously for 4 seconds.

Navigate to menu item 12 (refrigerant line address) using the Temperature SetButtons.Set a unique line address using the Timer Set Buttons and then press SET.Navigate to menu item 03 (network address) using the Temperature Set Buttons.Set a unique network address using the Temperature Set Buttons and then pressSETPress the CHECK button to complete the setting process

Generally speaking the refrigerant line address would mirror the network address,however this would not be the case with grouped units, which would have thesame network address but different line addresses.

Limitations

It is recommended that 1.5mm2 2-core screened cable be used on all networks upto a maximum of 500Mtrs in length.

The KRT range of units do not require adaptors as they are supplied with U3 & U4connections and also have a termination resistance facility on the indoor PCB. Thetermination resistance being set by SW01 bit 1 being set to ON.

6.1 RBC-WP1-PE Windows Control Package

Description

The RBC-WP1-PE is a front-end software package that controls all aspects of the airconditioning systems installed on a site. The software is installed on a PC, which thenconnects to a TCB-IFLN640TLE2 LonWorks gateway for connection to the indoor units.The software allows all of the units operating parameters to be adjusted from the one PC.It allows faults to be reported and re-transmitted via email, fax or text message. Thesoftware can be accessed remotely either by telephone or via the Internet. The softwarecan log data and provide graphical representation of data. It has a schedule built-in fortime control and it can also be used to reset set points or modes of operation.

When the software is installed, it will automatically install the gateways and power metersand it will then generate basic graphics.

Application

The software is used when a computer solution is required in order to provide a flexiblesolution to allow the air conditioning to be fully controlled from one central point. It offersmuch functionality, which is suited to small and large systems.

Features of the Software

CustomizationThe software being very flexible, it allows for a fully adaptable graphical representation ofthe building to be included.

Frost ProtectionThe software has the ability to sample the air temperature from an individual or a selectionof indoor units. Then, based on this data, operate the air conditioning to give frost andfabric protection to the building

Energy monitoringThe energy monitoring software can be included to calculate the running costs of theindividual indoor units. This data can then be provided in structured bills for the buildingtenants. This data is calculated from the demand given from the indoor units and thepower consumed by the system. The RBC-EM1-PE power meter is required for thisfunction. This option is covered in a separate data sheet.


43/72

43

Control of other devicesWe have a simple digital Input / Output module that we use to control other plant systems.For example, we could enable boilers or other air-handling units. The module can accept

inputs also; examples would be an input from a fire alarm where the air conditioners areshutdown or an input to switch on the air conditioners from an external source. The RBC-DI1 module is required for this function. This option is covered in a separate data sheet.

11.1 VN Unit Controls

Description

This section is subdivided into four sections for diferent applications of the VNunits. The VN is supplied with a 240V control option as standard this is a startingpoint but often requires development for specific applications.

Application

Option 1

The first option is the simplest form of control it does not allow control with the airconditioner system. The mechanical switch is straightforward to install as it onlyinvolves the switching of the relays. If required the fan speed or the damper can befixed in a particular mode

Option 2

The Second option allows the VN unit to be enabled from an indoor unit thisutilizes the RBC-SMFI Fan interface. This link means the unit needs to be operatedin conjunction with an associated indoor unit.

Option 3

Option 3 is a low voltage option, which gives a dedicated controller for the VN unitthis control option, will allow a Heater to be controlled to protect the fabric of theunit. This option can also be integrated with the indoor units via the RBC-SMFI faninterface.

Option 4

The final option indicates the procedure for connecting and control usinginteractive intelligence. This allows full control from the PC of the VN unit the unitscan independently time controlled to only provide ventilation when the building isoccupied.


65/72

65

Option 1: 3-Gang switch

The simplest form of ventilation heat exchanger unit (VN unit) control is with

electro-mechanical switches. These are not supplied by Toshiba but can beobtained from the usual DIY stores. Three switches should be used with one VNunit.
