Is your system labeled 120V-240V?
If so, your system is high voltage and is NOT compatible with ZEN.
If you’re unsure, please contact your home automation provider or HVAC installer.
Do you see thick wires with wire-nuts?
If you do, your system is high voltage and is NOT compatible with ZEN.
If you're unsure, please contact your home automation provider or HVAC installer.
Check the boxes below that correspond with the labels on the wire terminals of your old thermostat. You can disregard any links. Do not identify your wires based on colour.
TIP: Take a photo of your existing wiring in case you need additional HVAC support.
The way your old thermostat is wired is one of the best guides for how to wire up the Zen thermostat. Correctly identifying the wires that exist ensures that all the functions of your heating and cooling system will be able to be controlled by the Zen thermostat. If you are unsure or your wires terminals are unlabelled please contact your home automation provider or HVAC installer.
We require more information to confirm that Zen thermostat supports the wiring combination you have selected. Please check that you have identified the correct wires, or send us an image of your wiring to firstname.lastname@example.org and we'll get back to you with further guidance.
TIP: Attach the labels roughly 1in (25mm) away from the end of the wire to make reinsertion easier.
Labelling your wires before you remove your old thermostat saves time when installing the Zen thermostat and will be useful if you decide to change or upgrade your heating or cooling system in the future.
WARNING: Do not allow wires to fall into wall cavity.
WARNING: Ensure that any wires that will not be reconnected are properly insulated.
TIP: Check wires have between
5/16 - 3/8in (8-10mm) exposed core.
TIP: Use a level to help align the wall plate.
If your previous thermostat was larger, you may chose to use the blanking plate to cover any unsightly areas.
Use a 1/4in (6mm) drill bit if using the wall plugs
Ensure that the wires are kept out of the way when drilling
What type of heating do you have?
Zen thermostat will be configured to operate in the safest and most efficient manner, which is different for different types of heating systems.
Simply push the wires into the corresponding holes as shown in the image below.
The white Release Button can be pressed with a pen to make insertion easier or release the wire. You may need to twist the exposed core to help the wires into the holes.
After your wires are connected, make sure they are secure by lightly pulling on them. Ensure the wires are then pushed back and flush with the wall-plate.
Insert the 4 x AA batteries supplied with the unit.
When you insert the batteries the first screen you'll see will be the preferences screen.
Your system code ensures that the thermostat is configured correctly for your system. Press the CONFIG button once to enter configuration mode.

If you have a ZigBee enabled home network installed, you can connect this with your Zen thermostat to enable additional functionality such as controlling the temperature of your home with your smartphone.
The connection process can differ between systems, so please refer to the user guide that came with your home network.
Once you’ve set your home network to search for a new device, remove the display from the wall mount and press the NETWORK button 5 times (the thermostat will beep on each button press).
The wireless icon will start flashing when pairing with your home network. Once connected it will stop flashing and remain illuminated.
