Important tips

Before pairing your new Ezlo Thermostat to your home
controller, set the parameters to adjust the
thermostat's behavior. See Menu description and
Z-Wave parameters sections | pages 24–28 and 34–39.

If your Ezlo Thermostat has already been paired with
your home controller and you want to change the
parameters, please note that an exclusion and pairing
again will be required to update the UI controls and
thermostat capabilities on your controller.

Getting Started

Pairing with a Z-Wave Hub

Follow these quick steps to get up and running.
Each step includes a reference to where you can find the full procedure in this manual.

Wiring Setup

Begin by removing your existing thermostat and connecting the Ezlo Thermostat according to your HVAC system type.

Turn off power to your HVAC system.
Label existing wires before disconnecting them.
Mount the Ezlo base plate and wire the unit as per your system (conventional or heat pump).
Follow wiring diagrams and terminal descriptions for your specific system.

Continue on page 10–22 for the full wiring
instructions.

Thermostat Configuration

After wiring, configure the thermostat through its interface:

Power up the device.
Use the Secret Menu to set your HVAC system type.
Adjust display, fan, schedule, and offset settings as needed.
Set your preferred temperature units and other preferences.

Continue on page 23–28 for full configuration details.

Connect the thermostat to your smart home
system:

Open your Z-Wave controller’s app (e.g., MiOS for Ezlo hubs).
Put the controller in inclusion mode.
On the thermostat, press and hold ▲+▼ for 3
seconds to access Z-Wave menu.
Press ⦾ to enter learning mode.

Continue on page 30–31 for complete pairing instructions.

Once you've completed these steps, you're ready to enjoy smart, efficient climate control with your Ezlo Thermostat.

Once you’ve selected your desired temperature, press any button to save the setting and exit.

Mode Setting

With the screen on, press • — the mode icon will flash.
Press • again to cycle through modes:
• OFF→HEAT→COOL→AUTO→AUX
(Emergency Heating)
Press ▲,▼, or set • to confirm the desired mode.
The MODE icon will stop flashing.

Fan Mode & Schedule Setting

With screen on, long press • for 3 sec to enter settings.
Sequence: FAN MODE→SCHEDULE MODE→WEEK→TIME→EXIT
Use ▲ or ▼ to change values (icon flashes), press • to confirm.
If SCHEDULE MODE is enabled, the “SCHEDULE” icon will appear on the main screen.
Long press • for 1 sec or no input for 20 sec = Exit.

Fan Modes

Fan On: The fan runs continuously when the
thermostat is on. It stops only when the device is turned off.
Fan Auto: The fan runs only when heating or
cooling is active. It stops automatically when the system is idle or off.

Secret Menu

With the thermostat set to OFF, press and hold "▼"+ "•" for 3 seconds to enter the parameter settings.

Use "▼" or "▲" to scroll through parameter values.

Press • to move to the next setting.

To exit, press and hold "▼"+"•" for 1 second, or wait 20 seconds without activity.

Thermostat Setup for Each System Type

Once the thermostat wiring is complete, enter the Secret Menu to configure the system type settings.
This ensures the thermostat operates correctly in the desired mode (Heat, Cool, Auto, etc.).

Before pairing your new Ezlo Thermostat to your home controller, set the parameters to adjust the thermostat’s behavior. See Menu description and Z-Wave parameters sections |
pages 23–28 and 35–39.
If your Ezlo Thermostat has already been paired with your home controller and you want to change the parameters, please note that an
exclusion and pairing again will be required to
update the UI controls and thermostat
capabilities on your controller.

The brightness will return to the value set in the
Secret Menu or via Z-Wave configuration.

4. Display of fan mode and humidity icons can be
enabled/disabled through the Secret Menu or
Z-Wave configuration.
Note: These icons are hidden by default.

5. When the Schedule function is enabled, the
current time, weekday, and time period icons
can also be enabled/disabled through the
Secret Menu or Z-Wave configuration.
Note: These are shown by default.

Including the Z-Wave Thermostat to an Ezlo Z-Wave Hub

Step 1: In the MiOS app

1. Open MiOS and go to "More."

2. Select "Devices" and tap the "+" in the top right.

3. Choose your Ezlo Z-Wave Hub from the controller list.

4. Select "Thermostats" and select "Ezlo Thermostat" from the list

5. Follow the pairing instructions provided by the Wizard.

Step 2: On your Ezlo Z-Wave Thermostat

1. Press and hold "▼" and "▲" for 3 seconds to open the Z-WAVE menu.

2. If the thermostat is not connected, "---" will appear. Otherwise, the node ID is shown.

3. Press "•" to enter learning mode.

Note: Follow the same steps to exclude the device from the network. When removed from the Z-Wave network, the device restores it’s Z-Wave factory setting.

Including the Z-Wave Thermostat to other Z-Wave compatible hubs

Note: First, check the manual of the specific third party compatible how to include Z-Wave devices.

Step 1: Put the Z-Wave hub in including Mode.

Step 2: On the Thermostat

• Press and hold "▼" and "▲" for 3 seconds to open the Z-WAVE menu.

• If the thermostat is not connected, "---" will appear. Otherwise, the node ID is shown.

• Press “•” to enter learning mode.

Note: Follow the same steps to exclude the device from the network. When removed from the Z- Wave network, the device restores it’s Z-Wave factory setting.
