Volume flow coll. pump 1 at 100% set
value
1÷50 2
l/min
The volume flow at 100% set value of the pump collector 1 and aligned hydraulic. To calculate the volume flow
in your system, you can take 1 l/min per collector. In manual operating mode set Adjuster 8-85 to 100%. Read
the through-flow at the floating body volume flow meter.
08-50 all Strategy solar charging 0÷4 3 -
A basic strategy can be selected for solar charging:
Note: In the charging strategy it is attempted to charge the tank to the required set or maximum value with as few
charging cycles as possible. Based on the available solar energy, the controller attempts to maintain an even increa
-
se at the collector sensor throughout the whole charging time.
This optimised increase has a lower limit (Adjuster 8-64).
In the strategies 3 + 4 this calculation is only used with high solar energy levels.
0 = Parallel charging Charging in an alternating operation, the lowest tank is charged first.
The set value for the speed control is determined from the
temperature at the tank sensor + increase (Adjuster 8-64)
1 = Set charging Charging is carried out to the set value according to priority of the tank
(Adjuster 8-56). The tank with priority 1 is charged first to the set value
(Adjuster 8-62). The set value for the speed control is determined from
the temperature at the tank sensor + optimised increase.
2 = Maximum charging Charging is carried out to the maximum value according to priority of
the tank (Adjuster 8-56). The tank with priority 1 is charged first up to
the maximum value (Adjuster 8-59). The set value for the speed con
-
trol is determined by the maximum value + optimised increase
(Adjuster 8-64)
3 = Set charging dependent on energy Charging is carried out to the set value according to energy available
(Adjuster 8-51) parallel in alternating operation or according to priority
of the tank (Adjuster 8-56). The set value for the speed control is de
-
termined according to the active strategy.
4 = Maximum charging dependent on
energy
Charging is carried out to the maximum value according to the energy
available (Adjuster 8-51) parallel in alternating operation or according
to priority of the tank (Adjuster 8-56). The set value for the speed con
-
trol is determined according to the active strategy.

Change-over solar charging
(high energy levels)
30÷100 50 %
If the comparison of actual solar energy with the nominal performance gives a factor which lies above the setting
value, a change-over from parallel operation (alternating) to set value or maximum charging takes place.
The basic settings for the nominal solar performance (E8-30) are directly linked and must be correctly set.
