Electrical Installation
Connecting the Gas Heater or Heat Pump
The following installation instructions are for gas heaters and heat pumps. To connect the heater
fireman switch or external control cable plug to the motherboard:
1. Run a two-conductor cable from the heater fireman switch / external control to the low voltage
raceway to the motherboard in the EasyTouch load centre.
2. Strip the conductors 7mm. Insert the wires into the GAS HEATER two-screw terminals (J19) on
the motherboard. For wiring details, refer to “EasyTouch System Wiring Diagram,” on page 20.
3. At the heater, connect the wires in accordance with heater manufacturer’s instructions.
4. Do NOT disconnect or wire around the thermostat, pressure switch, high limit switch, or other
safety devices.
5. Select the pool or spa thermostat and toggle the heater to that setting.
6. Turn the thermostat for the selected setting to maximum.
