2.7 Actual value 1 of d.h.w. temperature
(TBWx)
The higher d.h.w. temperature acquired with the d.h.w. sensor will automatically be
displayed on this line.
Display Unit
0...140 °C
If only one d.h.w. temperature sensor is connected, lines 61 and 62 will show the same
value.
2.8 Actual value 2 of d.h.w. temperature
The lower d.h.w. temperature acquired with the d.h.w. temperature sensor will
automatically be displayed on this line.
Display Unit
0...140 °C
If only one d.h.w. sensor is connected, lines 61 and 62 will show the same value
For information about d.h.w. heating with 2 temperature sensors, refer to section "Input
B31/H2"
2.9 Display of maximum flue gas temperature
(TGxmax)
This display shows the highest flue gas temperature acquired since the last reset.
Display Unit
0...350 °C
Using the + / - buttons, the display can be reset to the current value. For that purpose,
both buttons must be pressed together for 3 seconds. The value is reset as soon as the
display stops flashing.
In the event of an open-circuit or short-circuit of the sensor, the display maintains the
maximum temperature value last measured. This value can be reset after rectification
of the fault.
