System and regulations. System
overview.
1 | AHU equipment (field supplied)
2 | AHU system controller (field supplied)
3 | AHU connection kit controller box (with
control PCB)
4 | Thermistor for gas pipe (E2)
5 | Thermistor for liquid pipe (E1)
6 | Thermistor for suction air
7 | Inter-unit wiring
8 | Outdoor unit

Control option 1.
· 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.
· System control by a 0-10 V control
working from an external BMS that
manages the set point for temperature or
capacity. Enhances efficiency by adjusting
capacity and enhances comfort as well
· All signals as standard
