4.11 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. temperature sensor is connected, lines 61 and 62 will show the same
value.
For information about d.h.w. heating with 2 sensors, refer to "input B31" in Index.
4.12 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.
To be used as a flue gas temperature sensor, input B8/B6 must be appropriately
defined (operating line 99).
4.13 Actual value of collector temperature (B6)
Temperature at the collector acquired with sensor B6. This value is used as a criterion
for charging d.h.w. or buffer storage tanks with solar energy.
To be used as a collector temperature sensor, input B8/B6 must be appropriately
defined (line 99).
