Auxiliary functions
Weekly pasteurisation
The pasteurisation function via the boiler will be blocked if, by
18.00 h on the day for which pasteurisation has been scheduled,
the cylinder temperature captured by the solar cylinder sensor has
been held above 65 °C for at least one hour.
To prevent the solar circuit pump(s) from seizing because of long
idle periods, it/they will be started daily (at 12.00 h) for approximately
five seconds (after being idle for more than 24 hours). This function
will only become effective, if the max. collector temperature (
SOL05
/
P05
) has been exceeded.
Anti-seizing pump
protection
To return to the standard values, set DIP 4 to "OFF" and back to
"ON". This also resets the hours run and yield values.
Loading the standard
values (reset)
The maximum cylinder and collector temperature achieved during
a day (0.00 h to 24.00 h) are captured. These are saved daily at
24.00 h and can be scanned at the BM or BM-Solar.
Maximum cylinder and
collector temperature
over 24 h
The values for hours run, daily and total yield can be reset via
the BM and BM-Solar by holding down the rotary selector for at
least 10 s.
Resetting
values
The hours run by the solar circuit pump(s) are captured and saved.
They are displayed at the BM and BM-Solar.
Hours run
With system configurations 2, 3, 4, 5, 6, 7, 9, 10 a DHW circulation
pump can be connected to output A3. This function is only available
in conjunction with the BM programming module with address 0.
In that case the DHW circulation pump is switched via the
defaulted switching times of the corresponding time program in
the BM (0).
