After securing the UWP, proceed to the wiring connections as outlined in the next section.
Wiring Terminal Designations
Understanding the wiring terminal designations is crucial for correctly connecting your Honeywell TH6210U2001 thermostat. The R terminal is for 24VAC power. The Rc terminal is for 24VAC cooling power. For two-transformer systems, R and Rc are separate. For one-transformer systems, R and Rc are joined by a slider tab. Ensure this slider tab is correctly positioned based on your system type (set the slider to the down position for 2 wires).
The C terminal is for the 24VAC common wire. The W terminal is for the heat relay. The Y terminal is for the compressor contactor. The G terminal is for the fan relay. Some models may have additional terminals. Note: Slider Tabs for U terminals should be left in place for T6 Pro models. Carefully identify each wire from your existing system and connect it to the corresponding terminal on the UWP. Incorrect wiring can damage your system or thermostat.
Wiring Conventional Systems
Wiring conventional systems, such as forced air and hydronic systems, requires careful attention to terminal designations. Before starting, turn off the power at the breaker box or switch; For a 1H/1C system with one transformer, connect the R wire to the R terminal and the Rc wire to the Rc terminal, ensuring the slider tab joins R and Rc. Connect the W wire to the W terminal for heat, the Y wire to the Y terminal for the compressor contactor, and the G wire to the G terminal for the fan.
For a 1H/1C system with two transformers, keep the R and Rc wires separate, connecting the heating transformer’s R wire to the R terminal and the cooling transformer’s Rc wire to the Rc terminal. Connect the common wire to the C terminal. Always double-check the wiring diagram specific to your heating and cooling system to ensure correct connections. Shaded areas in the manual apply only to TH6320U/TH6220U models or as otherwise noted. Incorrect wiring can cause damage.
Wiring Heat Pump Systems
When wiring heat pump systems, careful attention to detail is crucial. Begin by turning off the power at the breaker box or switch. For a 1H/1C heat pump system, connect the R wire to the R terminal and the Rc wire to the Rc terminal, ensuring the slider tab joins R and Rc. Connect the Y wire to the Y terminal for the compressor contactor, and the O/B wire to the O/B terminal for the reversing valve.
Connect the G wire to the G terminal for the fan, and the C wire to the C terminal for the 24VAC common. Shaded areas in the manual apply only to TH6320U/TH6220U models or as otherwise noted. For a 3H/2C heat pump system (TH6320U only), refer to the specific wiring diagram in the manual. Ensure all connections are secure and correct before restoring power. Incorrect wiring can lead to damage or malfunction of the heat pump system. Always consult a qualified technician if you are unsure about any wiring connections.
Thermostat Mounting
Once the wiring is complete, proceed with mounting the thermostat. Begin by carefully pushing any excess wire back into the wall opening to ensure it doesn’t interfere with the thermostat’s fit. Next, close the UWP (Universal Wall Plate) door, making sure it remains securely closed without any bulging. Proper closure is essential for a flush and secure mount.
Now, align the UWP with the thermostat; Gently push the thermostat onto the UWP until you hear it snap securely into place. This confirms a solid connection. Finally, turn the power back on at the breaker box or switch. The thermostat should now power up. If the thermostat does not power on, double-check all wiring connections and ensure the UWP is properly installed. A correctly mounted thermostat ensures accurate temperature readings and optimal performance. If you encounter any difficulties, consult the troubleshooting section of this manual or contact Honeywell customer support for assistance.
