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
switch 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.
