Direct mounted CVE (if solenoid
or other additional pilot needed
use Sl and Sll)

Indirect mounted CVE (for remote location). CVH
and CVE installation kit (¼"G adapters for Sl and Sll -
027B0995) to be ordered separately
ICAD EKC 361
If existing temperature control set-up includes EKC 366 interface controller your PLC needs adaptation to send the proper analog signal
directly to ICAD motor. Otherwise it can be replaced with EKC 361 controller and temperature sensor for stand-alone control

CVE replacement for CVQ
BC309632045439en-000101 | 1

CVQ to CVE
027B1139 CVQ (-1 – 5 bar) (-14.5 – 72.5 psi)
is replaced by 027B0980 CVE (-0.66 – 8 bar) (-9.5 – 116 psi)027B1140 CVQ (0 – 6 bar) (0 – 87 psi)
027B1141 CVQ (1.7 – 8 bar) (24.5 – 116 psi)
Note: To operate the CVE pilot an ICAD 1200 motor is needed (ordered separately) and will need powered with 24 V DC, 2 amp.
ICAD configuration
Parameter ;26 Valve type:
Choose 10, CVE pilot with ICAD 1200A (see Quick start guide ICAD)
Note: Parameter ;26 is password protected so a password of 11 will need entered into parameter ;10 to be able to view and make
changes to it.

EKC 361 controller configuration
Parameter n03 Actuator type:
1: CVQ -1 – 5 bar
2: CVQ 0 – 6 bar
3: CVQ 1.7 – 8 bar
4: CVMQ
5: KVQ
6: ICM/CVE
Choose 6(ICM/CVE) instead of 1, 2 or 3:
Parameter n32 Opening degree Max. limitation – ICM/CVE with ICAD
(When ICM/CVE has been selected (n03 = 6) the maximum opening degree % can be entered. The ICAD motor opening degree will
never go above this value). For full working pressure range of the CVE pilot set n32 = 90% OD. To limit the regulating pressure range
so the evaporator will not go below a certain pressure/temperature use the below table to determine what the ICAD opening
degree % is for the min. evaporator pressure you want and enter that opening degree value in parameter n32.
Parameter n33 Opening degree Min. limitation – ICM/CVE with ICAD
(When ICM/CVE has been selected (n03 = 6) the minimum opening degree % can be entered. The ICAD motor opening degree will
never go below this value). For full working pressure range of the CVE pilot set n33 = 23% OD. To limit the regulating pressure range
so the evaporator will not go above a certain pressure/temperature use the below table to determine what the ICAD opening
degree % is for the max. evaporator pressure you want and enter that opening degree value in parameter n33.
Parameter n07 Temperature transient phenomenon:
The EKC 361 controller includes 3 predefined transient
phenomenon's for best adaptation to the actual plant
- Fastest possible cooling Setting = 1
- Cooling with less underswing Setting = 0
- Cooling underswing unwanted Setting = 2
(default value = 2)
