The FocusPRO TH6000 Series supports 24‑V and 120‑V HVAC systems, including heat, cool, and heat‑cool modes․ Wiring follows standard Honeywell color codes: R, W, Y, G, C, and optional G for ground Verify voltage with a multimeter before connecting
Supported HVAC Configurations, Circuit Voltage, and Thermostat Wiring Diagram
The Honeywell FocusPRO TH6000 Series accommodates single‑stage heating, single‑stage cooling, and heat‑cool (dual‑stage) setups․ It operates on both 24‑V and 120‑V power supplies, making it suitable for most residential systems that use low‑voltage control wiring or standard line voltage․
For 24‑V systems the thermostat draws power from the R (red) and C (common) terminals; for 120‑V systems it uses the 120‑V supply directly and the R terminal for control signals․
Standard color‑code wiring for a 24‑V system:
- R – 24‑V power
- W – heating signal
- Y – cooling signal
- G – fan control (optional)
- C – common return
- O/B – reversing valve (heat‑cool only)
Standard color‑code wiring for a 120‑V system:
- 120V – line voltage
- R – control signal (24‑V)
- W – heating signal (24‑V)
- Y – cooling signal (24‑V)
- G – fan control (optional)
- C – common return (24‑V)
Below is a simplified wiring diagram illustrating the connections for both voltage levels․ The diagram shows the thermostat’s terminals labeled R, W, Y, G, C, and O/B, with arrows indicating the flow of power and control signals․ The diagram also highlights the optional fan‑control (G) and reversing valve (O/B) connections for heat‑cool systems․
When wiring, always verify the voltage and polarity with a multimeter before connecting the thermostat․ Use insulated wire and secure all terminals to prevent loose connections․ Refer to the full wiring diagram in the installation manual for detailed instructions on special configurations such as 3‑stage systems or multi‑zone setups․
The thermostat’s firmware automatically detects the voltage type during the initial power‑on sequence, simplifying installation․ If the system uses a 24‑V transformer with a 120‑V supply, the thermostat will switch to the appropriate mode without manual intervention․ For heat‑cool systems, ensure the O/B terminal is connected to the reversing valve; otherwise, the thermostat will not cycle between heating and cooling․ Finally, always double‑check the wiring against the manufacturer’s wiring diagram to avoid mis‑connections that could damage the thermostat or HVAC equipment․
