Parameter setup
A
.
Setting controller in Superheat control mode.
Make sure that r12 = 0 (OFF) and change the settings
The setting will depends on the system requirement.
Select Refrigerant
o30 = 1-42 (default non selected)
Select valve type
n03 = 0 - 9 (default is "non" i.e non valve selected).
On using EKA 164A display, check the valve
overview chart.
Define pressure sensor range in gauge bar
o20 = Min. Transducer pressure
o21 = Max. Transducer pressure
Set the application mode
For MSS control n21 = 1 (default)
For Load define control n21 = 2
Define min/max superheat
n10 = min. superheat reference
n09 = max. superheat reference
For fixed superheat define n09 = n10
Define MOP (optional)
n11 = maximum operating pressure
(default is 20 bar, max. 200 = MOP off)
Set force opening of the valve ( optional)
Start OD% (n17)
StartUp time (n15)
To start the supeheat control
Set r12= ON

Define the require current in mA RMS.
B
.
Setting controller in valve driver mode
using analog signal
Make sure that r12 = 0 (OFF) and change the
settings so they fit to their application:
Select Appication mode
o61 = 1 (remote/AI control)
Select Analog signal type
o10 = 2 (4-20mA)
(for other analog signal check the parameter list)
Select valve type
n03 = 17 (valve type, ETS C = 17)
for other valve types refer to valve overview table.
To start the controller in Valve driver mode
Set r12 = ON
B. Valve driver
Using analog signal.
Value
0 - 20 mA / 4 - 20 mA / 0 - 10 V / 1 - 5 V
No override
