Heatit Z-TRM2

Heatit Z-TRM2 is an electronic thermostat for electrical floor heating. The thermostat has a built-in Z-Wave chip that can be connected with Home Automation systems like Fibaro, Futurehome, Smarthings, Homeseer, Vera, Zipato etc.

Heatit Z-TRM2 is equipped with a single pole switch and it fits most System 55 frames (Elko RS16, Schneider Exxact, Gira, Jung etc.). The thermostat can withstand a load of max 13A /2900W at 230V. At higher loads the thermostat must control a contactor. The thermostat may be connected to two wired external sensors.

The thermostat has the capacity of up to 8 associations (relays, wall plugs etc.).

The thermostat is designed for electrical heating.



Due to the fact that many of our thermostats are available in 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.
