MI-HEAT MH7H-EH Z-Wave Thermostat INSTALLATION INSTRUCTIONS

MI-HEAT MH7H-EH Z-Wave Thermostat

Operating Range

The MCO Home Z-Wave thermostat MH7H-EH is suitable for controlling electric underfloor heating and other electric heating devices such as infrared heating panels, fan heaters or connectors. With the integrated Z-Wave module, this thermostat can be integrated into many Z-Wave enabled home automation systems. Thanks to the Z-Wave standard, products from a wide range of manufacturers can be used together in a wireless network (Z-Wave-capable Smarthome control unit required, please check compatibility in advance). This means that the MCO Home Z-Wave thermostat can also be used with many other Z-Wave products from other manufacturers in a common Z-Wave radio network. Alternatively, the thermostat can also be set and operated without a Z-Wave central unit using the device buttons.

The thermostat is intended for indoor mounting only. It is recommended to mount the thermostat at a height of approx. 1.5 m above the floor, where it corresponds approximately to the average room temperature. It should be protected from direct sunlight, covers or heat sources to avoid incorrect temperature readings.

• Disconnect the power supply by a circuit breaker or fuse before installation.
• First disconnect the display unit from the flush-mounted electronics module.
• Connect all wires according to the wiring diagram shown below.
• Slide the flush-mounted electronics module into the junction box and secure it with two screws. Then mount the display unit again.

	Sat – Sun	5:00	28°C	9:00	24°C	17:00	28°C	22:00	24°C

High temperature protection

• If the external temperature sensor detects a temperature value of more than 55 °C, the unit activates the high temperature protection and the electric heating is switched off. In addition, a high-temperature protection symbol appears in the display.
• If the external temperature sensor detects a temperature value below 50 C, the appliance returns to normal operation. The symbol for high temperature protection disappears.

Frost protection function (optional)

• When the built-in temperature sensor detects a temperature value below 5°C, the thermostat activates the frost protection function and switches on the heating source. Meanwhile, the frost protection symbol is shown in the display.
• When the built-in temperature sensor detects a temperature value above 8°C, the appliance switches off the frost protection and returns to normal operation.
• The frost protection symbol disappears from the display.

Note: If the unit is not connected to an external temperature sensor, only the indoor temperature symbol is displayed. If the unit is connected to an external temperature sensor, it displays the indoor temperature and the high temperature protection symbol.

Humidity display
In the normal work interface, press and hold the S1 and S5 keys to enter the humidity display. If you long press the S1 and S5 buttons again, the unit will return to the normal display.

Z-Wave operation

• In the normal user interface, hold down the S4 button for a long time to open the Z-Wave settings. If the unit is not yet registered in a Z-Wave network, “- -” is displayed on the screen.
• Then press the S4 button once to put the unit into learning mode and obtain a node ID. If the recording was successful, a Node ID is displayed on the screen after a few seconds.
• A Node ID can always tell us whether the device is in the Z-Wave network or not.
• Note: Follow the same steps to remove the device from the Z-Wave network.
• After removal, the unit will be reset to its Z-Wave factory settings.
• After the recording, switch the unit off and then on again. Now the device is ready to be operated by the controller/gateway in the Z-Wave network.
• Please refer to the table at the end of the instructions for the exact Z-Wave control commands.
