Refer to your existing thermostat wiring or system documentation to determine which wires are present and how they should connect to the T4 Pro.
Wiring the Honeywell T4 Pro
Understanding the Wiring Diagram
The installation manual provides a detailed wiring diagram, typically illustrating terminal labels such as R, C, W, Y, G, and others. Familiarize yourself with these before proceeding:
- R (Red): Power (24V hot)
- C (Common): Return path for power (if available)
- W (White): Heating control
- Y (Yellow): Cooling control
- G (Green): Fan control
Wiring Steps
- Turn off power to the HVAC system.
- Remove the old thermostat and label the wires using masking tape for identification.
- Connect the wires to the corresponding terminals on the Honeywell T4 Pro mounting plate:
- Ensure tight, secure connections to prevent future issues.
- Attach the thermostat to the mounting plate.
- Restore power and verify connections.
Special Wiring Considerations
- If your system lacks a C wire, the thermostat can run on batteries, but a C wire provides more reliable power.
- In systems with multiple stages or auxiliary heat, additional wiring may be necessary; consult the manual for specific instructions.
- For systems with a common wire, connect it to the C terminal; if not available, consider a power adapter or professional wiring assistance.
