7.4 Connecting the Remote Controller to the Heat
Pump
1. Isolate the mains power supply for the heat pump from the power
source.
Do not connect the remote controller cable with the power on.
2. Remove the wiring cover.
3. Connect the remote controller cable to terminals 1 and 2 on the
Terminal PCB. The remote controller has no polarity so it does
not matter which wire of the remote controller cable is connected
to + and -. Take care not to let your screwdriver etc. touch any
of the other electronic parts. Do not use a power driver. It can
damage the terminal screw holes.
4. If shielded wire is used, connect it to terminal 3 (GND) on the
Terminal PCB.
5. Securely fasten the remote controller cable with the cord
fastening fitting. Leave the display board waterproof cover
removed.
