Begin by attaching the new thermostat base to the wall, ensuring it is level. If necessary, use the provided wall anchors. Next, connect the wires to the corresponding terminals on the thermostat, matching the labels from the old system (e.g., R, W, Y, G, C, Rh). Secure the wires tightly to avoid loose connections. If your system requires a jumper wire, connect it between the RH and RC terminals. Once all wires are connected, mount the thermostat faceplate onto the base. Turn the power back on and test the system to ensure proper operation.
2.4 Checking Thermostat Operation
After installation, verify the thermostat’s operation by testing heating, cooling, and fan functions. Switch the system to “HEAT” and ensure the heating system activates. Repeat for “COOL” mode to check the cooling system. Test the fan by setting it to “ON” to ensure continuous operation. Check the display for accurate temperature readings and system status. Verify that the system cycles on and off correctly based on the set temperature. If issues arise, review connections and ensure all wires are securely attached.
