Setting the parameter CF75=1 hybrid exchangers are enabled; through the parameter dF35 is possible to
select witch probe is used for the regulation (external temperature or condenser temperature/pressure).
If external temperature is selected, hybrid exchangers regulation of both circuits works in parallel.
If condenser temperature/pressure is selected:
common condenser: the regulation is done according the higher value of pressure/temperature of
the circuits in summer and the lower value in winter
separated condenser: every exchanger is managed accordind the temperature/pressure of the
specific circuit
Parametres involved:
-
- Hybrid exchangers set point 1 in chiller (parameter dF27)
- Hybrid exchangers set point 1 in chiller (parameter dF29)
- Hybrid exchangers set point 2 in chiller (parameter dF28)
- Hybrid exchangers set point 2 in chiller (parameter dF30)
- Hybrid exchangers set point 1 in heat pump (parameter dF31)
- Hybrid exchangers set point 1 in heat pump (parameter dF33)
- Hybrid exchangers set point 2 in heat pump (parameter dF32)
- Hybrid exchangers set point 2 in heat pump (parameter dF34)
Summer operation mode:
Winter operation mode:
If the machine is switched on and external temperature or condenser temperature/pressure is inside the
differential:
machine in chiller and temperature/pressure inside the differential dF29: exchanger 2 ON
