Indoor Side Inlet Water Temperature Sensor:
The indoor side inlet water sensor (RT) from factory is placed in the submerged
pocket of the plate heat exchanger.
If a buffer tank is installed, the RT sensor can be moved to the buffer tank temperature
sensor inlet pocket and EV01 parameter value can be set to “1”. This stops the pump
running when compressor is OFF.
If the RT sensor can not be moved to the buffer tank temperature sensor inlet, the
EV01 parameter value must be set to “0” (factory default setting). This allows the
pump to continue to run so RT measured the same as butter tank water temperature.
6m long RT sensor
Important:
All temperature sensor must be separated (min 200 mm) from high voltage
power cables to avoid interference which will cause measured temperature
fluctuating and the heat pump may operate incorrectly.
