Gather Tools

Safety First: Power Off

Turn Off the Circuit Breaker

Before starting, turn off the power to your heating and cooling system at the circuit breaker. This prevents electrical shock. For gas - powered systems, also turn off the gas supply. Double - check with a voltage tester to ensure no power remains.

Removing the Old Thermostat

Remove the Cover

Carefully take off the cover of the old Home Thermostat. Note the wire connections; most thermostats have labels like “R” for power, “W” for heating, and “Y” for cooling.

Label and Disconnect Wires

Use a label maker to mark each wire according to its terminal. Then, loosen the terminal screws with a screwdriver and gently pull out the wires. Keep them organized to avoid confusion.

Installing the New Ocean Controls Limited Thermostat

Mount the Base

Take the mounting plate of the new thermostat and attach it to the wall using the provided screws. Ensure it’s level for proper operation.

Connect the Wires

Refer to the wiring diagram in the thermostat’s manual. Connect each labeled wire to the corresponding terminal on the new thermostat. Tighten the screws firmly to secure the connections.

Attach the Thermostat Unit

Once the wires are connected, attach the thermostat unit to the mounting plate. Some models snap into place, while others require additional screws.

Power On and Testing

Restore Power

Turn the power back on at the circuit breaker. The Home Thermostat should power up. If not, immediately turn off the power and check your wiring connections.

Test the Thermostat

Set the thermostat to a different temperature and select the heating or cooling mode. Observe if your system responds as expected. Check for any unusual noises or malfunctions.

Troubleshooting Common Issues

Thermostat Not Powering On

If the thermostat doesn’t power on, check the power supply and wire connections. A loose or incorrect connection may be the cause. Refer to the wiring diagram and retry.

System Not Responding

If the heating or cooling system doesn’t activate, review the wire connections and thermostat settings. Contact Ocean Controls Limited’s customer support if issues persist.
