Switch-on delay DHW (3535)
In addition to parameter 3533, this function can be used to set the delay
for the lag boiler to switch on when DHW charging is active. "DHW switch-
on delay" applies for simultaneous heat and DHW requests.
Auto source seq ch'over (3540)
The sequence of lead boiler and following boiler is defined by the source
sequence changeover and in this way, the utilisation of the boilers in a
cascade is influenced. After the set time has elapsed, the boiler sequence
is changed. The boiler with next higher device address operates as lead
boiler.
The operating hours transferred from the generator to the cascade master
are decisive for calculating the hours run.
The setting "- - -" switches off the source sequence changeover. The lead
boiler can be set under program no. 3544. The remaining boilers are
connected and disconnected in the order of their LPB device addresses
Auto source seq exclusion (3541)
The setting for the generator exclusion is only used in connection with the
activated generator sequence (program no. 3540). The generator
exclusion can be used to exclude the first and/or last boiler from the
automatic changeover.
None: The boiler sequence changes after expiry of the time set in prog.
no. 3540.
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
sequence of the device address.
Return setpoint min (3560)
If the return temperature drops below the return setpoint set here, the
return maintenance becomes active. The return maintenance enables
influences 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
between the cascade flow and return sensor is smaller than the minimum
temperature spread set here, a generator is switched off as early as
possible independently of the set lead strategy. Once the temperature
difference is sufficient again, the system is switched over to the set lead
strategy again.

Solar

Solar
If there is sufficient solar energy, the solar system can heat the swimming
pool, the domestic water storage tank and the buffer storage tank. The
priority for heating the individual storage tanks can be set here. The
system is protected by a frost protection function and an overheating
protection function.
