1. INTRODUCTION
Heatit Z-TRM6 is an electronic thermostat for electrical
underfloor heating. The thermostat can be controlled through
your Z-Wave™ network or via the buttons on the front. The
thermostat has a user friendly interface.
Heatit Z-TRM6 has 3 modes; Heat - Cool and Eco.
The thermostat fits in standard European junction boxes and
may be used with most System 55 frames. It has a sturdy metal
frame for secure fastening on the junction box. The thermostat
has one built-in room temperature sensor. Two additional
external temperature sensors may also be connected.
Heatit Z-TRM6 has active power metering and it gives you
real time information about your power consumption. It also
allows you to set the power metering value manually in case
of connection with a contactor.
The thermostat can be set up with multiple associations
and can be used as a master thermostat. It can also control
external relays and wall plugs.
Designed for electrical heating.
The thermostat can withstand a load of max 16A/3600W at
230VAC. We recommend a contactor for loads above 13A.
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 Z-WAVE 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 voltage (disable the fuse).
2. Open the junction box.
3. Connect the wires according to the description in Chapter
6; "Connections". Optional: Connect external wired sensors.
4. After verifying the connections, switch on the mains voltage.
