1. Ac power supply must be activated. The controller passes
an initialisation phase in which the operating control lamp
flashes red and green. After having finished the initialisation,
the controller is in automatic operation with factory set-
tings. The preadjusted system scheme is Arr 1.
2. - select Arr
- change into
-mode (see 2.1)
- select the system scheme by Arr-characteristics
- adjustment is saved by pressing button
Now the controller is ready for operation and should enable
an optimum operation of the solar system by the factory
settings made.
System survey:
Arr 1 : standard solar system
Arr 2 : solar system with after-heating
Corresponding channel is only available if the option heat
quantity measurement is deactivated (OWMZ).
MEDT
The channel antifreeze content (MED%) is only shown if a
medium other than water or Tyfocor LS / G-LS (MEDT
0 or 3) is used. The adjustment is only appropriate when
using other types of antifreeze.
