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)
