The Heatit Z-TRM6 digital room thermostat controls electric and water-based heating systems via a Z-Wave network or the buttons on its front panel. It has a built-in room temperature sensor and supports two additional external NTC sensors. The Heat, Cool, and Eco modes let you select the operating mode, while the LED display clearly shows the information.

The thermostat measures active power in real time, and ZeroX technology switches the relay at 0 V. It supports open-window detection, weekly scheduling via the Z-Wave gateway, and wireless OTA updates. It can operate as a master thermostat and control up to 10 other thermostats and 10 external relays.
