ThermalFlo Installation and User’s Guide
Relay Remote Controls
Electrical wiring must be in accordance with the latest edition of the NEC (NFPA 70) in the United States and
CEC (CSA 22.1) in Canada, unless local code requirements indicate otherwise. To connect remote control
equipment to the heat pump, perform the following steps:
1. Turn off the power to both the remote pool/spa control system and the heat pump.
2. Remove the front left panel of the heat pump cabinet, (
you do not need to remove the torque head
screw at the top left corner
).
3. Remove the electrical service panel to the heat pump. Remove the 4 bezel retaining screws from above the
electrical compartment and rotate the bezel downward. This will allow you to access the Remote terminals
on the back of the ThermalFlo HP control board for the remote control installation.
4. Run the wires from the pool/spa remote control system into the upper electrical compartment.
5. Connect the wiring from the pool/spa remote control system to the heat pump remote control terminals using
¼ in. “Fast On” connectors as shown in the figure below.
6. Rotate the bezel back upwards into position and reinstall the 4 retaining screws.
7. Replace the electrical service panel.
8. Replace the front left panel.
9. Restore power to the heat pump and the pool/spa remote control system.
