Connecting the Heat Pump to Automation
To connect the external control cable plug to the motherboard:
1. Run a two-conductor cable from the heat pump external control to the low voltage raceway to the
motherboard in the Pentair Automation control centre.
2. Strip the conductors 7mm. Insert the wires into the GAS HEATER two-screw terminals (J19) on the
motherboard.
3. At the heat pump, connect the wires to “remote on/off” on the terminal block.
4. Do NOT disconnect or wire around the thermostat, pressure switch, high limit switch, or other
safety devices.
5. Turn the thermostat for the selected setting to maximum.
