Air / Control type (Part 2)
With the room control with supply air
limitation the control works with the T/H
sensor in the return air intake and with a
second T/H sensor in the supply air.

Example (temperature):
Example (humidity):
Primarily the control works as for room air control, only if the measured supply
air temperature is lower than the start temperature
➋a the temperature set-
point is shifted. The extent of the setpoint increase is determined by a factor
which you enter, as a gradient
➌, in the menu.
The relationship, according to which this happens, is made clear by the graph
opposite. A steep gradient drastically corrects the failure to meet the supply air
temperature, but has the risk that the control circuit starts to oscillate.
With humidity control (only for rel. humidity) the setpoint shifts to the opposite
direction. If the adjusted starting humidity
➍ is exceeded by the measured sup-
ply air humidity, the setpoint is reduced. You can also enter a gradient factor
➎
for this. The relationship is shown in the graph opposite.
