Do you want to enter your own heating
periods?
The switching dial is equipped with tappets that can
be tilted. The heating periods are entered by tilting
the tappets within the required period of time:
–
Tappets tilted outward :
Normal temperatur
Tappets tilted inward:
–
Economy temperatur
The factory settings are as follows:
6:00 to 22:00
22:00 to 6:00
To set the heating periods accrding to your needs,
proceed as follows:
⇒ The 24-hour time switch AUZ3.1 has a 24-hour
switching dial. It carries 96 tappets, which
means four tappets per hour, giving a
resolution of 15 minutes. The shortest possible
heating period also is 15 minutes.
CE1B2224E / 02.02.1999
⇒ The weekly time switch AUZ3.7 has a 7-day
switching dial. It carries 84 pairs of tappets,
which means 12 pairs of tappets or 24
individual tappets per day. The resolution is
thus one hour. However, since - for mechanical
reasons - at least two tappets need to be tilted
together to set one heating period, the shortest
) can be
possible heating period is two hours.
Do you want to set the clock?
The switching dial can only be turned in clockwise
direction.
1. First, make a coarse setting:
Turn the switching dial slowly in clockwise
direction until the current time of day reaches
the time indicator (with the weekly dial, also
observe the weekday).
2. Now make the correct setting:
Turn the large hand until the time of day is
correct.

Subject to alteration
The change from wintertime to summertime, and
vice versa, must be made manually.
Does the LED light up?
If the LED lights up, you need to replace the
batteries within the next three months.
Do you want to change the batteries?
Get two new alcaline batteries type AA, 1.5 V.
Remove the battery holder, then the batteries,
insert the new batteries and replace the battery
holder. Caution: the setting data are maintained
for a maximum of one minute only!
Make certain the old batteries are disposed of
properly, in compliance with environmental
requirements.
Energy saving tips without sacrificing
comfort
Never allow room temperatures to exceed 21 °C.
Air out the rooms for short periods of time only, but
properly, with the windows wide open.
