INFORMATION
■
The wiring for connection is not included.
■
The remote controller, delivered in a kit, has to be
mounted indoors.

When the remote controller thermostat function is
used, select the installation location considering it
should be a place:
■
where the average temperature in the room can be
detected,
■
that is not exposed to direct sunlight,
■
that is not near a heat source,
■
that is not affected by outside air or air draught due
to e.g. door opening/closing,
■
where the display is kept clean,
■
where the temperature is between 0°C and 50°C,
■
where the relative humidity is maximum 80%.
NOTICE
Be careful not to distort the shape of the lower part of
the remote controller by over tightening the mounting
screws.

remote controller is installed as well:
■
Connect the electrical wires of both remote
controllers in the same way like described below.
