Mounting location
Mount the transmitter on a flat interior wall of the room to be controlled. Do avoid obstructions such as shelves,
curtains and recesses. Do not place near heat sources, draft channels. Do not expose to direct sunlight.
Installation
1.
Open the single screw on the cover and remove cover from mounting plate.
2.
Fix the mounting plate to the flush mounting box or the wall surface
3.
Connect the conductors to the terminals of the back part according to wiring diagram
4.
The end of the conduit at the sensor must be sealed to prevent false measurements due to draughts through
the conduit.
5.
Slide the two hooks on top of the cover into the two latches on top of the mounting plate.
6.
Close the cover.
7.
With a Philips-type screw driver of size #2, carefully tighten the front holding screw to secure the cover to the
back part. There is no need to tighten the screw too much.

Output signal con guration
The analog output signal type may
be configured with a jumper for 0-
10 VDC or 0-20 mA control
signals. The jumpers are located
next to the terminal connector of
each analog output. See table
below for jumper placement. The
factory setting is to 0-10 VDC.
The signal range may be set with
JP2 for both analog outputs. JP2
will only operate if the output
range specified with OP01 and
OP02 is left at the default position
of 0...100%. With any other
setting the position of JP2 has no
influence and the range defined
with the output parameters
applies.
