For the installer
9.1.2 CTC EcoLogic system 1 – Heat pumps
Up to 10 heat pumps (VPA1 to VPA10) can be itted together with their
respective charge pump (G11 to G20).
Charge pumps 1 and 2 (G11 and G12) can be controlled from EcoLogic,
while charge pumps G13 to G20 are controlled from their respective heat
pumps.
The heat pumps are powered separately, not from the CTC EcoLogic.
For more information, refer to the Installation and Maintenance instructions of
the respective heat pump.
9.1.3 CTC EcoLogic system 1 – Hot water
The hot water is preheated in the boiler by the heat pump and then heated
up in a separate hot water heater (DHW heater). Hot water (DHW) circulation
is obtained from the pump (G40). Fresh hot water from the hot water heater
is mixed in by the mixing valve and chilled water released down into the tank
before once more being heated up. The non-return valves are necessary
to ensure that circulation proceeds as intended. Control valves allow the
desired low of the circuit to be adjusted.
