CBA001 U2B HQ

Demand-dependent flow temperature control

· Plant on / off depending on demand from the consumers

(demand signal via KNX)

· Control of the chilled water pump, with pump kick and super-

vision of flow

· Control of the recooling pump, with pump kick and supervi-

sion of flow

· Control of the chilled water flow temperature by activating the

recooling pump and chiller

· Control of the recooling temperature via the recooling valve

and by activating the recooling fans

· Control of the chiller via compressor on / off command, refrig-

eration valve and a supervision input for the chiller's fault sta-

tus signal. The chiller can only be switched on when there is

flow of water through the evaporator and the condenser

The temperature of each office room is acquired and individually controlled. The heat and cooling demand from all

rooms is collected and transmitted to the heating plant (precontroller) and to the cooling plant. The heating plant is

controlled in dependence on the outside temperature and of the heating request by the precontroller. The cooling

plant is controlled in dependence on a cooling demand in the room. Non-occupancy periods during the night can be

programmed in a time scheduler for each room group. During these time periods (night, weekend, holidays), the

room temperatures are automatically reduced. Open windows are automatically detected and room temperatures

lowered / raised to save heating / cooling energy. Also during the day the temperature is slightly reduced when the

room is not occupied.
