5.2 Temperature Setting Knobs (g) and (h)
With these setting knobs, the desired room
temperatures for normal mode (g) or redu-
ced modes (h) are set. The temperature ran-
ge of each is from 6 to 30 °C.
5.3 Timer
With the selection of the appropriate opera-
ting mode, the timer makes possible the au-
tomatic switching between normal and redu-
ced modes. The shortest switching interval
(closest distance between two riders on the
7-day ring ) is two hours. The positioning ac-
curacy (distance between two adjacent posi-
tions on the 7-day ring) is 30 min.
5.3.1 Setting the Time
Turn the Plexiglas disk with the printed minu-
te hand (i) to set the actual time of day. Turn
the disk only in the clockwise direction. The
7-day ring (j) must not be turned. Observe
that the clock runs in 7-day operation. The
time setting (24 hr and weekday) can be
read off of the 7-day ring (j) at the time mar-
ker (m).

5.3.2 Setting the Switching Times

• Red rider
• Blue rider
For correct operation of the timer, the riders
must be positioned alternately in red/blue se-
quence.
Stick the red and blue riders (l) for each day
at the desired position of the 7-day ring (j).
Riders that are not used remain in the stora-
ge position (k).
