F15 FUNCTION (sensor function F15)
00 = Room sensor for heating circuit 2. If a further sensor
at the pulse input [IMP] is detected at this position an FBR
is evaluated.
01 = 0 - 10 V input => For Preset Collector set tempera-
ture. On evaluation see parameter V-CURVE in the ex-
pert/installation level.
02 = light sensor (for plausibility testing with solar – no
function in version V1).
03 = 0 - 10 V input preset for modulation. On evaluation
see parameter V-CURVE in the expert/installation level.
!
The internal determination of the burner requirement
is deactivated when this function is used.
!
It is exclusively the target set via the 0 - 10 V output
that applies. Any changes, such as those relating to
external heating circuits, hot water preparation or
the frost protection function are ignored. The
operating mode switch also has no effect on the
burner requirement, only on the internal and external
determination of requirement and distribution.

BUS ID (heating circuit number):
The heating circuits are sequentially numbered starting
with "01". heating circuit numbers must not be assigned
twice. Please only use "00" for replacement controllers
(see page 18).

(code no. required for input)
00 = 5 kOhm NTC sensor
01 = 1 kOhm PTC sensor
Here the type of connected sensor can be set (does not
apply to FBR, room sensor and solar sensor PT 1000
[connector VIII]).
