EEV (Electronical Expansion Valve)
Setting for Carel valve
Here you can adjust the setpoint for the superheating in normal operation ➊
and the setpoint for the superheating in case of dehumidification
➋. Both valu-
es must be entered as differences to the evaporation temperature.
Operate
The suction gas pressure and temperature are measured by a pressure sensor
and a temperature sensor and these values are transmitted via an EEIO board
to the controller. With these parameters the superheat is controlled by the
expansion valve.
➊. By the setting 1 the valve is configured and the failure of the pressure sen-
sor, the temperature sensor and the stepper motor for the valve control are
monitored and displayed by an alarm.
Setting 0 means: the valve is not configured.
➋. By this parameter the valve controller is determined. "ALCO VCM" and
"CAREL EVD" can be selected. Depending on the controller adjusted here dif-
ferent parameters can be adjusted. The parameters on a grey background are
not adjustable for the Carel controller.
➌. Here the valve type is determined.
➍. Setting of the refrigerant in use.
➎. Setting of the pressure sensor in use.
