Outgoing water temp control by HP unit
HP unit operates in order to reach the set point of Outgoing water temperature or Tank temperature (DHW tank or
Buffer tank).
Set point of Outgoing water temperature of Heating/Cooling can be Fixed or Climatic curve. To reach the set point
of Tank temperature, the Outgoing temperature shall be set as a Maximum water temperature (60°C) in Heating or
Minimum water temperature (7°C) in Cooling mode.
By Dual set point (Par5122, Terminal 22-23), the set point of Zone2 can be applied.
According to each Zone set point, the HP unit or water pump for each Zone can be turned ON/OFF.
Each sensor shall be defined as below, and the HP unit control in main system is as below 1) to 4).
S1= Sensor, Outgoing water temperature (on HP unit)
S2= Sensor, DHW tank temperature
S3= Sensor, Buffer tank temperature
S4= Sensor, Mixed water temperature
T1= Sensor, Room air temperature Zone1 (on Master Remote controller)
T2= Sensor, Room air temperature Zone2 (on Slave Remote controller)
1) Zone1 only
In the case of water temp control, Par4100=0, HP unit operates in order for S1 to reach the set point (Fixed or
Climatic curve).
In the case of room temp control, Par 4100=1, HP unit can be turned ON/OFF by T1 and set point of Remote
controller.
