The corresponding commands:
Here you can input a setpoint for the differential pressure ➀ of supply air. If this
value is different from zero, the differential pressure control will begin, see
chapter 6.5.
The parameter "standby delay"
➁ is only relevant in the context of the SAPSM
control, see chapter 6.6.
Here you can input a setpoint for the differential pressure
➂ between room air
and external air to control the exhaust air louver. This is a special function of
DFC² control. See manuals G17A and 18AA.
For the supply air pressure, which is measured by a sensor with the sensor pur-
pose 47 = supply air pressure in cPa, you can set an upper limit value ➎ and a
lower limit value ➊. Attaining these values triggers the alarms "supply air pres-
sure too high" or "supply air pressure too low". Additionally you can set an upper
➎a and a lower ➊a limit value for the prealarm (in the menu named "Warning").
For both alarms you can set the following alarm parameters:
1. alarm delay ➋ ➏ , prealarm delay ➋a ➏a
2. common alarm release ➍ ➑ , common alarm release (prealarm) ➍a ➑a
3. alarm priority/digital output ➌ ➐ , prealarm priority/digital output ➌a ➐a
In contrast to the principle not to modify the same parameter in different
menus, you can set the setpoints for supply air and room air pressure here,
which also can be adjusted in the menu Operate/Values/Air/Pressure.
