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
