Heatit Z-TRM2fx is an electronic thermostat with power metering feature for mounting in a standard wall box. The thermostat has a built-in Z-Wave chip and can be connected to Home Automation systems like Fibaro, Sensio, VERA, Zipato and others. The temperature shown in the display is the actual temperature for floor sensor and the external room sensor. When using the internal room sensor, the temperature shown is the set point. Z-TRM2fx thermostat equipped with a single-pole switch and can handle loads up to 13A/2900W at 230V. If the load is greater than this, the thermostat needs to be connected to an contactor. It can be used with two external temperature sensors.
