5. Setup and Installation
Proper installation is crucial for optimal performance. If you are unsure about any steps, it is recommended to consult a qualified HVAC professional.
5.1 Pre-Installation Checklist
- Ensure your system is compatible (refer to Section 4).
- Gather necessary tools: screwdriver, wire strippers, drill (if needed).
- Turn off power to your heating/cooling system at the circuit breaker before starting.
5.2 Wiring
The T5 Plus thermostat requires a common (C) wire for continuous power. If your existing thermostat wiring does not include a C-wire, use the included C-Wire Power Adapter.
- Remove your old thermostat's faceplate. Take a picture of the wiring for reference.
- Disconnect and label each wire from your old thermostat.
- If you have a C-wire, connect it to the 'C' terminal on the UWP mounting plate.
- If you do not have a C-wire, install the C-Wire Power Adapter near your heating/cooling system according to its separate instructions. This adapter provides the necessary power.
- Connect the remaining wires to the corresponding terminals on the UWP mounting plate. Refer to the wiring diagram provided with the thermostat.

5.3 Mounting
- Mount the UWP (Universal Wiring Plate) to the wall using the provided screws and anchors. Ensure it is level.
- Push any excess wire back into the wall opening.
- Align the T5 Plus thermostat with the UWP and snap it into place.

- Software Updates: Ensure your thermostat's firmware is up to date through the Honeywell Home app to access the latest features and improvements.
8. Troubleshooting
If you encounter issues with your thermostat, try the following troubleshooting steps:
8.1 No Power to Thermostat
- Check the circuit breaker for your heating/cooling system and ensure it is in the 'On' position.
- Verify that the C-wire (or C-Wire Power Adapter) is correctly installed and connected.
- Ensure the thermostat is securely snapped onto the UWP mounting plate.
8.2 Wi-Fi Connection Issues
- Confirm your home Wi-Fi network is active and broadcasting a 2.4 GHz signal.
- Restart your Wi-Fi router and modem.
- Ensure your thermostat is within range of your Wi-Fi router.
- Check your router's settings: Some users have reported issues with Universal Plug and Play (UPnP) being enabled by default on their routers. Disabling UPnP in your router settings may resolve connectivity problems.
- Re-attempt the Wi-Fi setup process through the Honeywell Home app.
8.3 Incorrect Temperature Readings
- Ensure the thermostat is not exposed to direct sunlight, drafts, or heat sources (e.g., lamps, appliances) that could affect its temperature sensor.
- Verify that the thermostat is mounted on an interior wall, away from exterior walls or windows.
8.4 System Not Responding to Thermostat
- Double-check all wiring connections at both the thermostat and your HVAC system.
- Ensure the system mode (Heat, Cool, Auto) is correctly selected on the thermostat.
- Allow a few minutes for the system to respond after making temperature changes, as some HVAC systems have built-in delays.
