Use electrical cable of the type NYM with the
following conductor cross section:
Make certain that the cable is voltage-free
and then connect the thermostat with the
three-conductor cable to the gas heater ac-
cording to the connection plan (
to
).

Putting into Operation
After the electrical cable is connected, insert
the top part of the thermostat
(a)
onto the
base

essentials for operation in brief form.
5.1
Mode Switch (f)
The following operating modes are possible:
Automatic switching between normal
and reduced modes at the times set on
the timer.
Normal mode: Continuous regulation
of the room temperature to the value
set with the knob
(g)
.
Reduced mode: Continuous regulation
of the room temperature to the value
set with the knob
(h)
.
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
= Normal mode.
• Blue rider
= Reduced mode.
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
