- Activate the ability to the thermostat on the circuit breaker panel.
| Battery Kind | 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 in the back of the thermostat and determine the widespread wire (often black, white, or blue), the heating wire (often purple 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 widespread wire and the purple probe to the heating wire.
- Verify 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 check by touching the purple probe to the cooling wire. You must also 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 | Answer |
|---|---|---|
| No voltage on the thermostat | Energy will not be reaching the thermostat. | Verify the circuit breaker or fuse for the thermostat. If the breaker or fuse is tripped or blown, reset or exchange 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 verify for continuity alongside the wire. If there is no such thing as a continuity, exchange the wire. |
| Voltage on the thermostat and furnace or air conditioner, however no heating or cooling. | Defective thermostat, furnace, or air conditioner. | Substitute the thermostat or contact an HVAC technician to verify the furnace or air conditioner. |
