4. Operation
Operating modes and status LED
The regulator compares the actual room temperature to the preset
reference temperature and adjusts heating and cooling installations in
accordance with the respective energy requirements. The temperature
reference value depends on the respective operating mode and can be
varied with the adjusting wheel (Fig. 1, 2). The operating modes and the
current regulator status are indicated by means of status LEDs (Fig. 1, 3)

LThe indication of the controller status can last up to 30 s.
Setting the mode of operation
Control elements for setting the operating mode are installed, e.g. touch
sensors, control panels, etc.
Activate the desired mode of operation with the corresponding control
element.
The new operating mode is indicated by means of status LEDs (Fig. 1,
3).
The reference temperature for the room is set in accordance with the
selected operating mode.
Changing the room temperature
To increase the reference temperature:
turn the adjusting wheel clockwise.
To lower the reference temperature: turn the adjusting wheel counter-
clockwise.
Activating the comfort prolongation
It is desired to prolong the comfort mode for a certain time beyond the
preset automatic switch-over of the operating mode. This can be ensured
by the comfort prolongation. The time for which the comfort prolongation
mode can be prolonged is limited.

The regulator is in the night-time mode or in the frost/
heat protection mode.
Press the presence button (Fig. 1, 1)
The LEDs or are lit up.
The reference temperature of the comfort mode is now active for the
pre-programmed time.
After the end of the programmed time span, the originally set night-
time or frost/heat protection mode is resumed
LThe comfort prolongation can also be activated
Lautomatically, e.g. from a presence detector.

be fatal.
Before working on the device, disconnect
the supply voltage and cover up live parts
in the working environment.
4.1. Fitting and electrical connection
Fitting and connecting the device
The device is composed of a terminal insert with supporting ring and
electronic attachment module (Fig. 2).
Do not use the regulator together with other electrical devices in the
same combination since the heat produced by these devices may
influence the temperature measurement of the regulator.
Do not use the regulator in the vicinity of heat sources such as electric
ranges, refrigerators, draughts of air or insolation to avoid wrong
temperature measurements.
The optimal fitting height is about 1.5 m.
Install the device in a flush-mounting box as per DIN 49073 or in a
surface-mounting box.
Recommendation: Use the deep type of box.
Detach the electronic attachment module (Fig.2, 6) from the terminal
insert (Fig.2, 4)..
Connect the bus line to the terminal insert using the connecting
terminals (Fig.3, 10).
