2. Elementary operator control 3

This room thermostat clock creates
comfortable room temperatures in the
simplest way possible.

The two temperature levels

= Comfort temperature

= Set-back temperature

are set with the appropriate dials.
Settings between

The manual switch can be used to
switch between three operating modes:

Operating mode = Automatic

The unit operates during the set switching
times and switches between and .

Please note that when switching the
manual switch from „Temperature “ to
„ “, the coloured mark on the manual
switch must be aligned for a short time
with the clock symbol on the unit to im­mediately activate the automatic mode.

Continuous temperature operating modes

= Comfort temperature

= Lower temperature

The manually selected temperature remains
constant until a different operating mode
has been selected.

Please remember when setting the
switching times that the heating system
requires a certain amount of time before
it reaches the desired temperature.

5°C and 30°C possible.

3. Installation notes 4

Assembly/installation should only be carried out by
qualified person exercising due care.
Switch off the heating system before assembly.
Check and make sure that the connection wires
are not live.

Assembly note:

– only use PVC-sheathed cables (solid wire)

during installation

– may only be attached to a non-conducting,

level and stable surface

– only suitable for ambient conditions where

normal quantities of dirt occur

– if installed properly in accordance with

VDE 0100, Part 40, the components where
contact remains possible may be regarded
as doubly insulated (Class of protection II)

Operating note:

This unit’s electronic unit has been protected
from external interference. However – depending
on the type of assembly – remember that the
mains voltage may be overlaid with extremely
high interference voltage peaks. Also, when
switching coils, e. g. solenoid valves, contactors,
interference occurs that may affect an electronic
unit in spite of all internal protective measures.
To guarantee the greatest operating safety, the
following details must be observed when
connecting:
– where larger plants are concerned, it will

be necessary to shield coils, e. g. solenoid
valves, contactors, that are switched directly
by the unit with a suitable varistor or
RC element

– if inductive DC voltage consumers are

switched, a free-wheeling diode must be
added

– inductive and capacitive loads especially

exert a lot of stress on the output contacts.
In individual cases check, whether the installation
requires
– an isolation relay or contactor or
– an interference suppression filter, e. g. Type
