StellaZ is a Z-Wave wireless Thermostat Valve capable of controlling heating, air ventilation and climate control units. The thermostat valve includes temperature sensor, control and actuator functions in a single device allowing stand alone control of a room's heating/ventilation.

The StellaZ can run in four different operation modes (Frost, Energy Saving, Comfort, Direct Control) and reports the room temperature to the Z-Wave network.

  • Frost Protection: The room's temperature will be regulated to about 6 °C.
  • Comfort: The temperature will be regulated to a comfortable level - factory default is 22 °C
  • Energy Saving: The temperature will be regulated to a energy saving level - factory default is 18 °C
  • Direct Valve Control: This mode allows the direct control of the valve as percentage value
  • Note: Comfort and Energy Saving modes can have their setpoint changed by the Z-Wave controller

The thermostat valve also includes an 'Open Window' function that automatically closes the valve when a window or outside door is opened.
