Preparing for Installation: Low Voltage Wiring Basics

Most modern HVAC systems use low voltage wiring (typically 24V) to control heating and cooling. The Wyze Thermostat is designed to work with these systems, but there are some important considerations:

• Check for a C-Wire (Common Wire): This wire provides continuous power to the thermostat. If your system lacks a C-wire, Wyze includes a C-Wire Adapter to ensure compatibility.
• Identify Your Wires: Common terminals include Rc (power for cooling), Rh (power for heating), Y (cooling), G (fan), and W (heating). Label each wire carefully.
• Avoid High Voltage Systems: Wyze Thermostat is not compatible with high voltage (110/120V) systems.

Troubleshooting Honeywell K-Wire Systems

If you have a Honeywell thermostat with a K-wire (which combines Y and G wires), you will need to remove the Honeywell wire saver to make your system compatible with Wyze. This involves:

• Removing the wire saver device
• Labeling and reconnecting wires individually at the control board
• Adjusting wiring at the thermostat by placing the C-wire into the G terminal and the K-wire into the Y terminal
