MI-HEAT -MH7H-EH- Z-Wave -Thermostat- PO

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.

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
