IMPORTANT
PLEASE READ THIS BEFORE INSTALLATION
This thermostat is tested and certified by Pepper One Gmbh
according to the requirements put forward by the Z-Wave
Alliance. This is a Z-wave Plus product with the 500 series chip.
If the product does not work with your gateway, then the
gateway manufacturer has not made an integration or
implemented such a thermostat with their gateway.
We do not give any guarantee towards integration.
PRINCIPLES FOR REGULATION
The Heatit Z-TRM2 is designed for controlling electrical heating
cables and electrical radiators/convectors. The thermostat
has built in temperature sensors and has 3 algorithms for
temperature compensation. After you have set the temperature,
the thermostat will use a hysteresis to regulate the temperature.
The hysteresis is adjustable.
TEMPERATURE SHOWN IN DISPLAY
The temperature shown in the display is the actual temperature
for floor sensor and the external room sensor. You are able
to calibrate the sensor values. When using the built in room
sensor, the temperature shown is the set point. When using the
built in sensor, the thermostat can seem somewhat inaccurate.
This is due to heat generation inside the thermostat, draft and
other external influences. If the thermostat is to be used with
waterbased heating systems, you have to use an external sensor.
You may show the calculated temperature see parameter #17.
Z-WAVE THERMOSTAT – SETUP
This manual describes the most essential functions and
technical specifications of the thermostat. These instructions
help the user to control the thermostat, and the electrician to
install and setup the thermostat.
FACTORY RESET
By pressing buttons Right and Center (down and confirm) for 20
seconds, the thermostat will perform a complete factory reset.
NB! Please use this procedure only when the primary controller/
gateway is missing or otherwise inoperable.
BEHAVIOUR WITHIN THE Z-WAVE NETWORK
This product can be operated in any Z-Wave network with other
Z-Wave certified devices from other manufacturers. All non-
battery operated nodes within the network will act as repeaters
regardless of vendor to increase 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 wireless network
to communicate with the devices of this network. Devices can
also be removed from a network. Both add and remove process
are initiated by the primary controller of the Z-Wave network.
This controller will be turned into a mode for adding or
removing devices. Please refer to your primary controllers
manual on how to turn your controller into add or remove
mode. Only if the primary controller is in add or remove mode,
this device can be added or removed from the network. When
the device is removed from the network, it will set the device
back to factory default.
If the device already belongs to a network, follow the remove
process before adding it in your network. Otherwise, the adding
of this device will fail.
INSTALLATION
Installation must be done by a qualified electrical installer in
accordance with the National Building codes. Before installation,
disconnect any power to the thermostat’s mains. During
installation of the thermostat, power to the thermostat must be
disconnected AT ALL TIMES!
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 can now be removed.
Now connect the wires to the thermostat’s terminals:
Use 1,5mm² or 2,5mm² according to load.
