Function and operation

District or communal heating system – the primary thermal energy is used to produce
domestic hot water and heating.

Domestic hot water (DHW) - the DHW is prepared via a plate heat exchanger. The
electronically controlled Pressure Independent Control Valve (PICV) modulates the primary
flow rate to maintain the DHW temperature. This unit operates with the DHW taking priority
over HTG – when the hot water is used it will temporarily cut the heating operation. Once
the hot water outlets are closed the heating operation will be resumed.

Heating (HTG) – when the space heating demand is requested by the end user controller,
the heating operation is started. The electronically controlled PICV is used to modulate the
primary flow rate to match the heating demand. The unit has an integrated heating
circulation pump which is switched on when the heating is on.

Keep Warm Facility – when the heat interface unit is set in the Comfort mode, the DHW
plate heat exchanger is kept warm by opening the domestic hot water PICV to heat the plate
up to comfort temperature. This cycle runs about 3-5 minutes.

District or communal cooling system
– the primary chilled water flow is used to produce
cooling.

Apartment cooling – when the space cooling demand is requested by the end user
controller, the cooling operation is started. The electronically controlled PICV is used to
modulate the primary flow rate to match the cooling demand. The unit has an integrated
circulation pump which is switched on when the cooling is on.
