Flue gas thermostat reset button

A malfunction in the flue gas discharge, e.g. a
blockage in the chimney, can lead to the flue gas
thermostat locking out. This state is evident when the
push button on the flue gas thermostat has been
activated (refer to the figure). Once the cause has
been removed, and the sensor has cooled down
sufficiently, press this push button to reset (if the
sensor is not sufficiently cooled down, the flue gas
thermostat will immediately lock out again). The
appliance will then automatically start up again, if
there is demand. If this is not the case, please consult
the error condition summary

Weekly timer circuit

Optionally, you can use the week timer to program
when the appliance must fulfil demand. Set the
ON/OFF switch to the 'II' position to activate the
weekly timer circuit.
Weekly timer
Legend
1 timer
2 weekly disc
3 pointers
4 manual switch
5 tabs
The weekly disk (2) of the timer (1) is divided into
seven one-day segments: 'Monday' through 'Sunday'.
Each day is divided into 12 segments of 2 hours each
by the setting tabs (5).
To set a two-hour period during which the appliance
must respond to demand, press the tab for that period
outwards.
The current time can be read from the (12-hour) clock
hands (3).
Set the day and time as follows: to set roughly, turn the
week disk (2) in the direction of the arrow until the
current day of the week is aligned with the marker
arrow; for fine setting, turn the large hand clockwise
until the current time is set. The manual switch (4)
must always be in the central position (this activates
the timer program).
