The Mill WiFi Max heater is easy to control with the Mill App, no matter where you are in the world. In the app, you can conveniently program the temperature to automatically adjust to your daily routines. That way, you save the environment from unnecessary use of electricity, and you save yourself the unnecessary expense. In addition to being stunningly beautiful, this model has the same heating element you can find in all Mill panel heaters, which means it can safely operate without supervision.

PID control

When desired temperature is reached, the heater will maintain this temperature by lowering the power level, resulting in a more stable heating with less fluctuation in temperature.

Predictive heating

The panel heater will heat the room so that the desired temperature is reached at a specific time. The heater learns how fast the room goes up/down in temperature over time. That way, it will know when to start heating to achieve your desired temperature at the time you have scheduled in the Mill-app.

Easy connection

Seamless and easy connection with Bluetooth that automatically connects the device to your WiFi-network, regardless of the type of router you have.

Child safety lock

Activate the child lock in the Mill app to lock all buttons on the control panel of the heater. This prevents nosy little fingers from adjusting the temperature, or turn the heater on and off.

Commercial lock

Ensures that you as a landlord have control over the temperature and electricity consumption in the rental properties in the Mill app.
