temperatures):
F t2C
or alternating mode .
-
Controller mode (the switching state input “open” or “closed” can allotted to two different control
temperature sources. E. g. internal

external control):
F Con
or type of control .
The following functions are made available by the outputs:

Signal various fault states:
F diA
or fault diagnosis .
-
Signaling standby:
F Stb
or Standby .
-
Providing status of the window discriminators (inside

outside):
F WXi
or temperature range .
-
Providing the programmer status:
F Pr6
or Programmer .
-
Signaling refill of heat transfer liquid:
F F1L
