• Expansion Valve Control: For controlling the Electronic Expansion valve the program uses a brick named Superheat Control,
where the logic work like an EKE controller. For basic superheat control, one Evaporator temperature sensor (TetempeatureValue),
and one pressure sensor (suction pressure) are needed. The actual superheat is calculated based on these two sensor readings,
and the controller will adjust the OD (open Degree) of the valve to bring the superheat to the desired reference. If superheat is too
low the flow in the expansion is decreased and superheat will be higher and vice versa.
