6.3 Setpoint offset
The current setpoint can be offset via object 25 "
Manual adjustment
" by up to +/- 5 K
manually.
With every alteration, the adjusted setpoint is transmitted by the
Current setpoint
object
(object 27).
The limits of the offset are set on the
Operating mode and operation parameter page
with the
Limitation of manual offset
parameter.
On this parameter page one can also define in which operating mode a setpoint offset should be
possible, see parameter
Manual offset is valid
.
6.4 Setpoint adjustment
The setpoint adjustment allows a dynamic adjustment of the setpoint to the outdoor temperature
when cooling.
If the outdoor temperature exceeds a set threshold, adjustment is activated and a corresponding
increase of the setpoint is calculated.
6.4.1 Use with internal controller
The setpoint adjustment can also be applied to the internal controller, if the
Use setpoint
adjustment for control
parameter is set to
yes
.
In this case, the setpoint of the internal controller (
Base setpoint after reset
) is always adjusted
relatively, i.e. increased or decreased by the calculated correction value
(see figure 2 below).
Moreover, an independent setpoint can be generated, which makes the adjustment for further
controllers in the building available (see below: Format of the setpoint correction: Absolute).
6.4.2 Use with external controller
There are 2 types of setpoint correction available for external controllers, the relative and
absolute type.
