5.1 Basic systems and hydraulic variants
System
The controller is preprogrammed for 7 basic systems. The selection depends on
the number of heat sources (collector fields) and heat sinks (stores, pool). Factory
setting is system 1.
A solar system with store charging in layers is implemented as a 2-store
system (store top = store 1; store base = store 2).
The selection of the basic solar system is one of the most important adjustments
and is thus requested already in the commissioning menu.
First, the basic system is adjusted by means of the number of stores and collectors
fields, then the hydraulic variant.
The selected system is visualised by the corresponding number of store and collec-
tor symbols. The figure to the left shows system 6 which consists of 3 stores and 2
collector fields ("east- / west collectors").
Variant
The hydraulic variant refers to the different actuators that are to be controlled.
They are visualised on the display by means of symbols, when the variant is select-
ed. The upper symbol indicates the actuator belonging to the collector fields, the
lower one the actuators belonging to the stores.
The exemplary figure shows the display indicated when system 6, variant 2 has
been selected. In this case, each collector field has a 2-port valve, the stores are
loaded by means of pump logic.
For each variant, the controller allocates the corresponding relays and sensors. The
allocations of all combinations are shown in chap. 5.2.

- 1 store
System 2: east- / west collectors - 1 store
System 3: 1 collector field
- 2 stores
System 4: east- / west collectors - 2 stores
System 5: 1 collector field
- 3 stores
