Outdoor Ambient Temperature Sensor:
The outdoor temperature sensor (OT) is a standard part placed inside the electric box. One
terminal is connected with the PC board X3 and GND, the other terminal must be installed
outdoors. It should be mounted on a wall that has the mean outdoor temperature which can
accurately measure the outdoor temperature and not to be exposed the rain, sun and snow.
If the outdoor ambient temperature sensor cable runs close to power cables a shielded cable should
be used. If a conduit is used, it should be sealed to avoid condensation in the outdoor temperature
sensor probe.
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.
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.
