5. Pemasangan

Before beginning installation, ensure the power to your HVAC system is turned off at the circuit breaker. This thermostat is designed for easy DIY installation, but professional assistance is recommended if you are unfamiliar with electrical wiring.

5.1 Gambarajah Pendawaian

The thermostat supports various wiring configurations. Refer to the diagrams below to identify the correct wiring for your system. The thermostat can be powered by 24VAC or AAA batteries. If powered by batteries, a C-wire is not required.

Figure 5.1: Wiring schematics for common system types.

• Typical 1H/1C System (1 Transformer): Connect R to Rh (with jumper to Rc), W to W, Y to Y, G to G. C-wire is optional if using batteries.
• Cool Only System: Connect R to Rh (with jumper to Rc), Y to Y, G to G. C-wire is optional if using batteries.
• 1H/1C Heat Pump: Connect R to Rh (with jumper to Rc), W to W, Y to Y, G to G. If the system defaults to heating mode, connect the reversing valve signal wire to the B terminal. If the system defaults to cooling mode, connect the reversing valve signal wire to the O terminal. C-wire is optional if using batteries.

Figure 5.2: Wiring schematics for heating-only and volt-free systems.

• Heating Only System with Fan (Gas Fireplace 24V, Gas/Electric/Oil Furnace Forced-Air Heating): Connect R to Rh (with jumper to Rc), W to W, G to G. No C-wire required if the thermostat is powered by batteries.
• Heating Only without Fan (Hydronic Heating System): Remove the jumper wire between Rh and Rc. Connect R to Rh, W to W. No C-wire required if the thermostat is powered by batteries.
• Volt-Free System Heating Only (750 Millivolt/Boiler System): Remove the jumper wire between Rh and Rc. Connect R to Rh, W to W. The thermostat should be powered by batteries, and a C-wire is not needed.

5.2 Memasang Termostat

1. Turn off power to your heating/cooling system at the circuit breaker.
2. Remove your old thermostat from the wall.
3. Label the wires connected to your old thermostat with the corresponding terminal letters.
4. Mount the new thermostat's backplate to the wall using the provided screws and anchors.
5. Connect the labeled wires to the appropriate terminals on the new thermostat's backplate according to the wiring diagrams in Section 5.1.
