Wiring Terminal Designations
Each terminal is clearly identified for specific wiring connections‚ including Rh‚ Rc‚ W‚ Y‚ G‚ and C․ Understanding wire colors aids proper installation․
Identifying Each Terminal
The thermostat’s wiring terminals are crucial for correct operation․ ‘Rh’ and ‘Rc’ are for 24VAC power‚ often jumpered if a single wire exists․ ‘W’ activates heating‚ ‘Y’ controls cooling‚ and ‘G’ energizes the fan․ A common wire‚ ‘C’‚ provides a return path for power‚ essential for reliable Z-Wave connectivity․ Carefully identify each wire before connecting; incorrect wiring can damage the system․ Refer to your HVAC system’s wiring diagram for accurate identification and ensure power is off during installation․
Understanding Wire Colors
While wire colors aren’t standardized‚ common conventions exist․ Red often indicates 24VAC power (Rh/Rc)‚ white typically connects to the heat wire (W)‚ yellow usually signifies cooling (Y)‚ and green often designates the fan (G)․ The common wire (C) is frequently blue․ However‚ always verify wire functions with a multimeter and your HVAC system’s documentation․ Never rely solely on color coding‚ as previous installations may deviate from these norms․ Incorrect connections can cause system malfunction․

Wiring Conventional Systems: Forced Air and Hydronics
Forced air systems utilize standard wiring for heat‚ cool‚ and fan․ Hydronic systems‚ employing hot water‚ require specific wiring for zone control and pump activation․
Wiring a Forced Air System
When wiring a forced air system‚ connect the Rh wire to the 24V common (C) terminal․ The Rc wire connects to the Rh terminal․ W connects to heat‚ Y to cool‚ and G to the fan․ Ensure proper wire connections‚ securing them firmly within the terminal blocks․ Double-check all connections against your existing thermostat’s wiring before powering on․ Incorrect wiring can damage the thermostat or HVAC system‚ so proceed cautiously and consult a professional if unsure․
Wiring a Hydronic System
For hydronic systems‚ connect the Rh wire to the 24V common (C) terminal‚ and Rc to Rh․ The W wire connects to heat‚ typically controlling a zone valve․ Ensure the system is off before wiring․ Verify proper wire connections and secure them firmly․ If your system uses a separate transformer‚ confirm it provides the correct voltage․ Incorrect wiring can lead to system malfunction or damage․ Always consult a qualified HVAC technician if you are unfamiliar with hydronic system wiring․
