The set flow temperature is compared with the tempera-
ture at one or two store (buffer) reference sensors (diffe-
rential control). If this temperature differential is to small
(DTHon), afterheating will be activated. It will be switched
off, if the differential (DTHoff) between store and set flow
temperature is large enough.

selection: “None“, “Therm.“, “Store“
factory setting: “None“
Select the after-heating type via the parameter “Aft.-Heat.“
(“None“, “Therm.“, or “Store“).
If “None“ is selected, no afterheating will be carried out.
If “Therm.“ is selected, the set flow temperature is compared
with a store reference sensor.
If “Store“ is selected, the comparison is made with 2 refe-
rence sensors. The switching conditions to both reference
sensors have to be fulfilled.
With this parameter, the 1
st
reference sensor for heating
circuit afterheating can be selected.

With the parameter “HC Relay var.“ it is possible to choose
different relay allocations for the heating circuit pump and
heating circuit afterheating. Factory setting “1“ is the standard
relay allocation (see 3.5).
If “2“ is selected, the relays of the heating circuit pump and
HC-afterheating are interchanged.
If “3“ is selected, HC-afterheating is allocated to relay 9
and the heating circuit pump to relay 5 (for systems 1 - 4
only).
As soon as in the basic systems 1 - 5 an option referring
to relay 6 is activated (or relay 3 in basic systems 6 and 7
respectively), the parameter “HC Relay Var.“ will be blocked.
Therefore, the following steps have to be carried out in the
correct order (see also 3.4):
1. Select basic solar system and hydraulic variant
2. Activate heating circuit and select relay allocation.
3. Activate options (e.g. store loading).
