4. COMMISSIONING
7a. Scheme (if 6. = Scheme):
Enter the scheme number of the desired system.
7b. Selection of the solar system (if 6. = System):
Adjust the desired solar system (number of collectors and stores, hydraulic variants).
8. Completing the commissioning menu:
After the system has been selected or the scheme number has been entered, a security enquiry
appears. If the security enquiry is confirmed, the adjustments will be saved.
Î In order to confirm the security enquiry, press button ➄.
Î In order to reenter the commissioning menu channels, press button ➆.
If the security enquiry has been confirmed, the controller will be ready for operation.
NOTE:
The adjustments carried out during commissioning can be changed anytime in the cor-
responding adjustment channel. Additional functions and options can also be activated
and adjusted (see page 128).
Set the code to the customer code before handing over the controller to
the customer (see page 173).
4.1

BASIC SYSTEMS

The controller is pre-programmed for different basic systems. The selection depends on the
number of heat sources (collector fields) and heat sinks (stores, pool).
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 number of collector fields and stores will have to be adjusted, then the hydraulic
variant.
NOTE:
A solar system with store loading in layers is implemented as a 2-store system (store top
= store 1; store base = store 2).
The system selected is visualised by the corresponding number of store and collector symbols.
The exemplary figure shows system 2.3.x with 2 collector fields and 2 stores.
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 selected. 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 2.3.2 has been selected.
In this case, each collector field has a 2-port valve, the stores are loaded by means of pump
logic.
The controller allocates corresponding output and sensor settings for each basic system. The
allocations of all combinations are shown in chap. 4.2.
