Number of operating cycles

2 Check the number of operating cycles (heater ON):
the number of operating cycles can be displayed
by pressing and holding the RESET button. The
number of operating cycles is composed as fol-
lows in alternating displays:
The first character (X.) stands for X,000,000 op-
erating cycles, the second character (Y) stands
for Y00,000 operating cycles. For example, the
first character is the number 2.: the unit has ex-
ceeded 2,000,000 operating cycles. The second
character is the number 3: the unit has exceeded
300,000 operating cycles. The total number of
operating cycles is composed of the numbers
2 and 3. This gives a total number of operating
cycles of 2,300,000.
3 Disconnect the system from the electrical power
supply.
▷ The heater may only be disconnected from the
electrical power supply once the device has been
switched off and post-cooling is complete.
4 Shut off the gas supply.
