• Heating or cooling does not start when the thermostat calls for operation.
• Temperature control is inaccurate or inconsistent.

Installation and Safety

1. Turn off HVAC power at the service disconnect or breaker before opening the thermostat or disconnecting wires.
2. Verify power is off with an appropriate meter and follow the equipment and thermostat service instructions.
3. Photograph the original wiring and label every wire by terminal position. Do not infer connections from wire color.
4. Have a qualified HVAC technician confirm system voltage, stages, wiring, equipment compatibility, and power arrangement.
5. Mount the replacement securely and connect each wire to the correct terminal. Never bypass an interlock, fuse, or thermal safety control.
6. Restore power and run a supervised heating and cooling test.
7. If the system behaves unexpectedly, turn power back off and have the wiring and equipment diagnosed by a qualified technician.
