Function block "Service functions
and general settings"
Function block "Service functions and general settings" is used to combine various
displays and setting functions that are of assistance in connection with commissioning
and service work. In addition, a number of extra functions are performed.
The service functions are independent of the type of plant.

25.2.1 Flow
temperature setpoint
Displayed is the current flow temperature setpoint which is made up of the following
variables:
•
Flow temperature setpoint in function of the composite outside temperature and the
heating curve
•
Position of the knob for room temperature readjustments
•
Parallel displacement (setting on operating line 72)
With demand-compensated control (plant types 4–x, 5–x, and 6–x), the display
shows ---.
