1) No cut/Stop: AHU system / indoor unit is completely switched OFF.
2) No Limit: No restrictions applied by BMS to AHU system / indoor unit performance (equivalent to “full-load operation“ of AHU
system / indoor unit).
Control option 1: PAW-280PAH2L
· The system’s control is simple: control of actual suction temperature vs. set point
· Control works in the same way as that of any indoor unit
· Fan signal issued by the PCB (OFF while defrosting, for instance)
Control option 2: PAW-280PAH2
· System control by probe located at air intake. Sensor works as a 0–10V control thermostat which manages the set
point temperature. Control to prevent cold draughts.
· All signals as per standard
Control option 3: PAW-280PAH2
· System control by external environment probe. Sensor works as a 0–10V control thermostat which manages the
set point temperature. Enhances efficiency by adjusting capacity to the ambient temperature and enhances
comfort as well.
· All signals as per standard
Control option 4: PAW-280PAH2
· System control by a 0–10V control working from an external BMS that manages the set point for the temperature or
the capacity. Enhances efficiency by adjusting capacity and enhances comfort as well.
· All signals as per standard
