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)

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).
