First: The first boiler in the addressing works as the lead boiler; for all
the other boilers the boiler sequence is changed after expiry of the time
set in prog. no. 3540.
Last: The last boiler in the addressing always remains the last boiler; for
all other boilers the boiler sequence is changed after expiry of the time
set in prog. no. 3540.
Leading source (3544)
The setting of the leading generator is only used in combination with the
fixed sequence of the generator sequence (prog. no. 3540). The generator
defined as the leading generator is always put into operation first, and
switched off last. The other generators are switched on and off in the se
quence of the device address.
Return setpoint min (3560)
If the return temperature drops below the return setpoint set here, the re
turn maintenance becomes active. The return maintenance enables influ
ences on the consumers or use of a return controller.
Temp differential min (3590)
This function prevents too high cascade return temperatures and improves
the switch off behaviour of the cascade. If the temperature difference be
tween the flow and return sensor is smaller than the minimal temperature
spread set here, a generator is switched off as early as possible independ
ently of the set lead strategy. Once the temperature difference is sufficient
again, the set lead strategy is switched over again.

The switching-on and switching-off point of the collector pump is set with
these functions. Basis is the temperature difference between collector
temperature and storage temperature.
Charg temp min HW st tank (3812)
In addition to the temperature difference, reaching a certain minimum col
lector temperature is necessary for the storage charging process.
Temp diff on buffer (3813),Temp diff off buffer (3814)
andCharging temp min buffer (3815)
The switching-on and switching-off point of the collector pump is set with
these functions. Basis is the temperature difference between collector
temperature and storage temperature of the buffer storage tank.
In addition to the temperature difference, reaching a certain minimum col
lector temperature is necessary for the buffer storage charging process.
Temp diff on swi pool (3816) andTemp diff off swi pool (3817)
The solar circuit pump starts or stops if the difference between the solar
collector temperature and the swimming pool temperature is exceeded or
undershot.
Charging temp min swi pool (3818)
Temperatures that the collector must have at the least in order to begin
charging a swimming pool.
