1. 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 230VAC.
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.
2. STATEMENT REGARDING PRODUCTS FROM MULTIPLE
MANUFACTURERS
Please read this before installation
This device may be used with all devices certified with the Z-Wave
Plus™ certificate and should be compatible with such devices
produced by any manufacturer. Every primary controller is different
depending on the manufacturer, their target audience and intended
use/application. Please review the functionalities implemented by the
primary controller you intend to use with our Z-Wave Plus certified
device to ensure that it provides the necessary controls to take full
advantage of our product’s capabilities.
3. BEHAVIOR WITHIN THE ZWAVE™ NETWORK
This device may be operated within any Z-Wave network with
Z-Wave-certified devices from other manufacturers. All non-battery-
operated nodes within the network will act as repeaters regardless of
manufacturer to increase the reliability of the network. On delivery, the
device does not belong to any Z-Wave network.
The device needs to be added to an existing network to communicate
with the other devices within it. Devices may also be removed from
a network. The add/remove processes are initiated by the primary
controller of the Z-Wave network.
4. QUICK START
1. Switch off the mains supply (disable the fuse).
2. Open the wall switch box.
3. Connect wires according to the labeling described in
chapter 5 ”Installation”.
4. After verifying the connections, switch the mains supply back on.
5. Set the primary controller in add mode (security/non-security).
6. Press and hold the center button until “OFF” is shown on the display
(approx. 10 seconds).
7. Press down button until you reach “CON”, press and hold until the
display shows a rotating light pattern.
8. The thermostat will display “INC” when the thermostat is successfully
added.
NB! If adding/removing fails, Err (error) will appear.
