• Page 8: Wiring notes Read the instructions before starting up the unit. Power input range is 20-28 V AC. Make sure the toggle switch for the wiring panel is in the right position. Do not expose the device to moisture, water, or other liquids. Do not attempt to disassemble, repair, or modify the device yourself. This product is for indoor use only. The C terminal is not required for battery power supply but is required for external AC power supply. Risk of electric shock - more than one disconnect switch may be required to de-energize the equipment before servicing. Always make sure to turn off power to the system before beginning any wiring work. If the current thermostat contains mercury, it must be disposed of according to federal, state, and local regulations.
• Page 9: Ezlo thermostat front plate Removal / disassembly Installation steps Remove the old thermostat if you have an existing one Disassemble the front plate of the Ezlo Z-Wave thermostat Attach the base plate to the wall and pull the existing wiring through the base plate Re-attach the front plate to the back plate Wire the Ezlo Z-Wave thermostat for your specific HVAC system Add the thermostat to your Z-Wave network
• Page 10: Removing the existing thermostat from heat pump systems involves several steps. Switch off the power to the HVAC system at the unit or circuit breaker panel. Take off the cover of the existing thermostat to access the wiring terminals. Snap a photo of the wiring terminals for troubleshooting later. Label the wires connected to the terminals using the provided wiring labels. Ensure to label the wires according to the terminal labels, not by wire color. Remove the base of the old thermostat carefully to avoid letting the wires fall back into the wall. Typical wire colors and their functions include yellow for cool, white for heat, green for fan, red for 24V AC return, and blue for 24V common.
