HEATIT Z-TRM3 Thermostat User Guide
INTRODUCTION
Heatit Z-TRM3 is an electronic thermostat for electrical floor heating, designed to be mounted in a standard flush box. The thermostat has a built-in Z-Wave chip that can be connected with Home Automation systems. Heatit Z-TRM3 is equipped with a single pole relay and fits into System 55 frames. The thermostat can withstand a load of max 16A /3600W at 230V. The thermostat may be used for water based heating if the thermostat is linked with the Heatit Z-Water.
NB! If the sensor mode is changed to A or AF mode then a room sensor compensation process will start, which limits maximum power output to 75%. The thermostat adapts to the environment within a few days. No internal sensor calibration should be performed during the first few days.
INSTALLATION
Use e.g. a small slotted screwdriver. Start by carefully removing the front
cover by pushing the release springs. The front cover and the frame may now be
removed. Connect the wires to the thermostat terminals: Use 1,5mm² or 2,5mm²
according to load.

FLOOR SENSOR NTC type (10, 12, 15, 33 or 47kΩ). Standard 10kΩ.
EXTERNAL SENSOR NTC type (10, 12, 15, 33 or 47kΩ). Standard 10kΩ.
Next, position the thermostat and fasten it onto the wall mounting box using
2-4 screws. Position the frame, then position and carefully press the front
cover until it snaps in place. Check that the front cover has snapped in place
properly on both left and right side. The front cover should now be firmly
fixed on all sides. To be able to to read the Power Metering, the load needs
to be connected to both heating L + N.
