Outdoor Ambient Temperature Sensor:
The outdoor temperature sensor (B3) is a standard component and is prewired and
positioned in the unit. The probe is located at the back of the unit in a protective
casing. The outdoor sensor is terminated on the PC board B3 and GND.
Temperature sensor for hot water:
The hot water sensor (B4) is connected to terminal positions B4 and GND on the main
board, the other terminal must be put into hot water cylinder temperature sensor probe
inlet pocket if required.
If the hot water sensor cable runs close to power cables, then a shielded cable should
be used. If a conduit is used then it should be sealed to avoid condensation forming in
the temperature sensor probe
．
Indoor Side Inlet Water Temperature Sensor:
The indoor side inlet water sensor (B1) from factory is placed at inlet water pipe.
If a buffer tank is installed, the Inlet water temperature sensor B1 can be moved to the
buffer tank temperature sensor inlet pocket and EV01 parameter value can be set to
“work by regulation”. This stops the pump running when compressor is OFF.
If the Inlet water temperature sensor B1 can not be moved to the buffer tank
temperature sensor inlet, the EV01 parameter value must be set to “continuous work”
(factory default setting). This allows the pump to continue to run so Inlet water
temperature sensor B1 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.
