Heatit Z-TRM2fx

Heatit Z-TRM2fx 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-TRM2fx 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 5 associations (relays, wall plugs etc.).

The thermostat is designed for electrical heating. It can also be used for waterborne floor heating when linked with Heatit Z-Water.
