NIBE™ VVM 300all IN oNE INdoor uNIt
NIBE VVM 300NIBE VVM 300 is an all in one inddor unit. It consists of a double jacketed pressure vessel, two immersion heaters and intelligent controls. VVM 300 is designed for connection and communica-tion with outdoor heat pump F20XX of 6 kW, 8 kW and 10 kW. For example floating condensation and automatic speed control for optimal performance of the load pumpconnected to the out-door unit.
VVM 300 is equipped with an intelligent control.
the insulation consists of environmenal friendly polyurethane, which is moulded in one piece.

Transport and storageNIBE VVM 300 must be transported and stored upright and dry. the VVM 300 may, however, be carefully laid on its back when being moved into a building.
MaintenanceGreat importance has been placed on the design of the control panel to achieve the most simple operation possible. a minimum level of maintenance is required. only safety valves require check-ing. all essential components can be accessed from the front. this facilitates service and maintenance.
Erecting the heat pumpElectric boiler ideally located in utility room or boiler room. the unit can be aligned using the adjustable feet.
route pipes so they are not fixed to an internal wall that backs on to a bedroom or living room. the minimum ceiling height is 2.0 m.
EquipmentVVM 300 is equipped with a complete set of valves, consisting of a drain valve, filling valve, vacuum valve, non-return valve, and safety valve for the water heater section. the boiler section is equipped with a drain valve, filler valve and safety valve. In addi-tion, the unit is equipped with climate controlled automatic by-passes with outdoor and flow sensors, shunt valve, circulation pump and expansion vessel.
Hot water temperatureWe recommend you to use the VVM 300 in combination with F2026 for heating systems up to max 55 °C the coldest day.

InstallatIon
Inspection of the installationCurrent regulations require the heating installation to be inspect-ed before it is commissioned. the inspection must be carried out by a suitably qualified person and should be documented. the above applies to installations with a closed expansion vessel. If the electric boiler or the expansion vessel is replaced, the instal-lation must be inspected again.
Maximum boiler and radiator volumesthe volume of the expansion vessel (85) is 12 litres and it is pres-surised as standard to 0.5 bar (5 mvp). as a result, the maximum permitted height between the vessel and the highest radiator is 5 metres.
If the standard initial pressure in the pressure vessel is not high enough it can be increased by adding air via the valve in the ex-pansion vessel. the initial pressure of the expansion vessel must be stated in the inspection document. any change in the initial pressure affects the ability of the expansion vessel to handle the expansion of the water.

Charge pump
Pipe installationall pipe connections are equipped with 22 mm compression ring couplings.
Radiator connection
radiator circuit connects to terminal (70), flow line and terminal (71), return line.
In units where the radiator flow can completely stop due to all thermostat valves being in the closed position, “bypass” valves must be installed to protect the circulation pump.
Tap water connection
Hot and cold water are connected to terminal (74) mixed water and (73) (cold water).
the electric boiler can be supplemented with an extra hot water heater if a bubble pool or other significant consumer of hot wa-ter is installed.
Docking connection
docking connection from F20XX is connected to terminal (75). docking connection to F20XX is connected to terminal (76). rec-ommended dimension of charge circuit is min Ø28 mm.
Heat regulationSunlight and heat emissions from people and household ma-chines are normally sufficient to keep the house warm during the warmer parts of the year. When it gets colder outside, the heat-ing system must be started. the colder it is outside, the warmer radiators and floor heating system must be.
Control of the heat production is performed based on the “float-ing condensing” principle, i.e. the temperature level needed for heating at a specific outdoor temperature is produced guided by collected values from the outdoor and flow sensors. as an op-tion, room sensors can also be used to compensate for variations in room temperature.
the supply of heat to the house is regulated in accordance with the chosen setting of the regulating curve (curve slope and off-set). after adjustment, the correct amount of heat for the out-side temperature is supplied. the flow temperature (menu 2.0) will hover around the theoretical required value (the value in brackets on the display). For subnormal temperatures the con-trol system calculates a heating deficit in the form of “degree-minutes”, which means that heating production is accelerated. the larger the subnormal temperature, the greater the heat pro-duction.
there are 8 stages to heat production, one for the heat pump and 7 for the electrical module.
VVM 300 is easy to install. all pipe connections are easily accessible. this is especially useful for the replacement market.

Electrical connections
Connection
VVM 300 must be installed via an isolator switch with a mini-mum breaking gap of 3 mm. other electrical equipment, except the outdoor sensor and the current sensors, are connected at the factory.
disconnect the electric boiler before insulation testing the house wiring.
Connection must not be carried out without the permission of the electricity supplier and under the supervision of a qualified electrician. the cable entry conduit is dimensioned for cable with a max Ø 19 mm.
the power is controlled via contactors, which are operated by a the control system.
the automatic heating control system, circulation pump (16), charge pump (40) and its cabling, are internally fuse protected with a miniature circuit breaker (7).
InstallatIon
Outside sensor
Install the outside sensor in the shade on a wall facing north or north-west, so it is unaffected by the morning sun. Connect the sensor with a two wire cable.
If a conduit is used it must be sealed to prevent condensation in the sensor capsule. the minimum cable cross section should be 0.4 mm2 up to lengths of 50 metres, for example, EKKX or liYY.
Centralised load control and load monitor
Centralised load control or tariff control achieved by activation of external potential free closing contact.
VVM 300 is equipped with an internal load monitor. the control system must be set for the installation’s main fuse so that the load monitor can work correctly. the supplied current sensor (20) is connected to VVM 300 by a 4 wire cable.
Cable type: unscreened liYY, screened liYCY. Cable area, at least 4 x 0.25 mm2 with cable length up to 50 m.
When the load monitor senses an overcurrent on one of the phases, the immersion heater will step down the output until it can be connected again.

dockIngs
NIBE VVM 300 can be connected in several ways. Further option information is available at www.nibe.eu.
VVM 300 docked to F2XXXVVM 300, together with F2XXX, creates a complete heating and hot water unit. VVM 300 is equipped with a control box that currently makes it the most economical operator, regarding both for the in-tegrated immersion heaters (max 13.5 kW) and compressor opera-tion in F2XXX.
VVM 300 comes complete with an automatic by-pass, three way valve, circulation pumps, and safety equipment. VVM is designed for simple connection to F2XXX.
VVM 300 controls F2XXX, which runs with floating condensation to-wards the heating system.
If F2XXX cannot meet the heating requirement, additional heat is shunted in from VVM 300. When the outside temperature drops below the set stop temperature VVM 300 engages and takes over the heating.
