1. AC power supply must be activated. The controller passes
an initialisation phase in which the operating control lamp
flashes red and green. At this point the controller is in au-
tomatic operation with factory settings.
Arr 1. Controller is ready for operation o the user may
activate the 2nd relay:
2. - Arr 2: Extended Solar System (with second relay)
-locate Arr by holding down forward key for 2 seconds
-press center key to begin set
-increase to Arr 2 using forward key
-press center key to save adjustment
Now the controller is ready for operation.
4. Controller parameter and indication channels
4.1 Channel-overview
Legend:
x
Corresponding channel is available.
x*
Corresponding channel is available if the appropriate option
is activated.

Corresponding channel is only available if the option heat
quantity measurement is activated (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.

Corresponding channel is only available if the option heat
quantity measurement is deactivated (OWMZ).
Please note:
S3 and S4 are only indicated if sensors are connected.
