Heatit Z-TRM3 User manual

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.
Connect the wires to the thermostat terminals: Use
1,5mm² or 2,5mm² according to load.
