8.10 Processing an external demand in control circuit RK1
The controller can process binary or analog requests for an externally required signal by a
more complex secondary system. A binary request can only be processed when the inputs
SF2 or RF2 are not assigned to a sensor.
NOTICE
Overheating may occur in the heating circuits of the primary controller without con-
trol valve.
Excessive charging temperatures in DHW circuits without control valve controlled by the pri-
mary controller are excluded when the default settings of the controller are used: while stor-
age tank charging is active, no ow temperature higher than the charging temperature is
used by the primary controller. Nevertheless, if the Priority for external demand function is
activated, the external demand is also processed during storage tank charging.

Priority for external demand 0 CO4 > F16 - 1
Binary demand processing
Regardless of the operating mode set for control circuit RK1, except for manual mode, the
controller regulates the ow temperature when either the binary input (terminals 03/12) is a
make contact ('Active when BI' = OFF) or a break contact ('Active when BI' = ON) in control
circuit RK1 to at least the adjusted ow temperature adjusted in PA1 > P10 ('Minimum ow
temperature set point HC for binary demand processing').
