Heatit 7S Thermostat

The Heatit 7S is an electonic thermostat with four functions. The thermostat is easy to install and program, and the simple design makes it very user-friendly. It is available both in black and white, and with two different frame designs.

The Heatit 7S is equipped with a single-pole switch. The thermostat can handle loads up to 16A/3600W at 230V. If the load is greater than this, the thermostat needs to be connected to a contactor. It may be used with two external temperature sensors.

The thermostat is designed for electrical heating.


Due to the fact that many of our thermostats are available both white and black, you may combine frames and fronts as you please. Choose a black frame with a white front (or the other way around) for an edgy look, or go for the traditional all-white or all-black.
