Optg mode changeover (1680)
Using external switching above the inputs H1-H5 it is possible to select
which operating mode is to be switched into.
Off: The function is switched off.
9.2.8 Consumer circuits/Swimming pool circuit
Flow temp setp cons request (1859, 1909, 1959)
Setting of the flow setpoint is done with this function, which is effective
during active request of the consumer circuit.
Hot water charging priority (1874, 1924, 1974)
Setting as to whether domestic hot water charging takes priority over the
consumer circuit/swimming pool circuit or not.
Excess heat draw (1875, 1925, 1975)
If an excess temperature discharge is activated, the excess energy can be
discharged heat being drawn by the consumer circuits. This can be set
separately for each consumer circuit.
With prim contr/system pump (1880, 1930, 1980)
No: The consumer circuit is supplied without primary control unit/system
pump
Yes: The consumer circuit is supplied from the primary controller on/by
the system pump.
9.2.9 Swimming pool
Setpoint solar heating (2055)
When solar energy is used, the swimming pool is heated to the setpoint
set here.
Setpoint source heating (2056)
When using the generator heating, the swimming pool is heated to the set­
point set here.
Charging priority solar (2065)
Setting of which priority the swimming pool will be solar heated. The priori­
ty for the DHW and charging buffer is set under Prog. no. 3822.
Priority 1: The swimming pool is heated before the buffer is charged.
Priority 2: The swimming pool is heated while the buffer is charged.
Priority 3: The swimming pool is heated after the buffer is charged.
Swimming pool temp max (2070)
This parameter sets whether the swimming pool heating by solar charging
has priority or not. If the swimming pool temp reaches the heating limit set
here, the collector pump is switched off. It is again released if the swim­
ming pool temp has dropped by 1°C below the maximum heating limit tem­
perature.
With solar integration (2080)
Setting, of whether the swimming pool heating can be done by solar ener­
gy or not.
9.2.10 Primary control/feed pump
Flow temp setpoint min (2110) and Flow temp setpoint max
(2111)
With these boundaries a range for the flow setpoint can be defined.
Syst pump on heat gen lock (2121)
This parameter can set whether the system pump is also locked or not
when the generator lock is active.
