- Shut the battery compartment and reattach the thermostat to the wall plate.
- Activate the ability to the thermostat on the circuit breaker panel.
| Battery Sort | Measurement | Voltage |
|---|---|---|
| AA | AA | 1.5V |
| AAA | AAA | 1.5V |
| CR2032 | CR2032 | 3V |
| LR44 | LR44 | 1.5V |
Checking the Wiring
7. Utilizing a multimeter to check voltage on the thermostat:
- Flip off the ability to the thermostat on the breaker or fuse field.
- Find the wires behind the thermostat and determine the frequent wire (often black, white, or blue), the heating wire (often pink or blue), and the cooling wire (often inexperienced or yellow).
- Set the multimeter to measure AC voltage.
- Contact the black probe of the multimeter to the frequent wire and the pink probe to the heating wire.
- Examine the show of the multimeter for a voltage studying. A studying of 24 volts or greater signifies that energy is reaching the thermostat.
- Repeat the take a look at by touching the pink probe to the cooling wire. You also needs to get a voltage studying of 24 volts or greater.
- If you don’t get a voltage studying on both wire, there could also be an issue with the wiring or the ability provide to the thermostat.
Wiring Troubleshooting:
| Symptom | Doable Trigger | Resolution |
|---|---|---|
| No voltage on the thermostat | Energy isn’t reaching the thermostat. | Examine the circuit breaker or fuse for the thermostat. If the breaker or fuse is tripped or blown, reset or substitute it. |
| Voltage on the thermostat, however not on the furnace or air conditioner. | Damaged wire between the thermostat and the furnace or air conditioner. | Use a voltage tester to examine for continuity alongside the wire. If there isn’t any continuity, substitute the wire. |
| Voltage on the thermostat and furnace or air conditioner, however no heating or cooling. | Defective thermostat, furnace, or air conditioner. | Change the thermostat or contact an HVAC technician to examine the furnace or air conditioner. |
