CAUTION
As a disclaimer and precautionary note, if you are not familiar with or comfortable on electrical wiring, it is best to call in a professional electrician to install your smart thermostat. Please do not attempt to install your smart thermostat if you do not have a general understanding of electrical wiring.
Wiring CAUTIONS ⚠️
- Read the instructions before starting up the unit!
- Do not expose the device to moisture, water or other liquids. Do not place liquids near or on the device!
- Do not attempt to disassemble, repair or modify the device yourself! This product is for indoor use only. Do not use outdoors!
- Risk of Electric Shock - More than one disconnect switch may be required to de-energize the equipment before servicing.
- Compressor protection is bypassed during testing. To prevent equipment damage, avoid cycling the compressor quickly
- WARNING: Always make sure to turn off power to the system before beginning any wiring work and double-check all connections before turning the power back on.
- WARNING: If the current thermostat contains mercury, it must be disposed of according to federal, state, and local regulations. Many states and local agencies offer collection or exchange programs, or hazardous waste disposal services for mercury-containing devices.
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 (fig.1)
- Attach the base plate to the wall and pull the existing wiring through the base plate (fig.2)
- Re-attach the front plate to the back plate (fig.2)
- Wire the Ezlo Z-Wave Thermostat for your specific HVAC system
- Add the thermostat to your Z-Wave Network

fig.2: Shows the base plate being separated from the front plate, with mounting holes labeled 'A' and connection points labeled 'B'. Dotted lines indicate how wires pass through the base plate.
Removing the Existing Thermostat
- Switch off the power to the HVAC system, either at the unit itself or at the circuit breaker panel.
- Take off the cover of the existing thermostat to reveal the wiring terminals.
- Snap a photo of the wiring terminals; this can be useful for troubleshooting later.
- Label the wires connected to the terminals using the provided wiring labels.
- Be sure to label the wires according to the terminal labels, not by the wire color.
- Remove the base of the old thermostat.
- Take care not to let the wires fall back into the wall.
