Operation
Display
The values will be shown with three digits, and with a setting you can
determine whether they are to be shown in °C or in °F.
LED’s on the front panel
There is one LED on the front panel which will light up when power is sent to
the pilot valve.
There are furthermore three LED s which will flash if there is an error in the
regulation. In this situation, you can show the error code on the display and
cut out the alarm by giving the upper button a brief push.
The controller can give the following messages:
El| Errors in the controller
Ell| Valve’s actuator temperature is outside its range
0.00E+00| Input signal outside its range
The buttons
When you want to change a setting, the two buttons will give you a higher or
lower value depending on the button you are pushing. But before you change the
value, you must have access to the menu. You obtain this by pushing the upper
button for a couple of seconds – you will then enter the column with parameter
codes. Find the parameter code you want to change and push the two buttons
simultaneously.
When you have changed the value, save the new value by once more pushing the
two buttons simultaneously.

Examples of operations
Set the valve’s basic temperature reference
- Push the two buttons simultaneously
- Push one of the buttons and select the new value
- Push both buttons again to conclude the setting
Read the valve’s regulating reference
-
Push the lower button
(After approx. 20 seconds the controller automatically returns to its setting, and it again shows the valve’s actual temperature)
Set one of the other menus -
Push the upper button until a parameter is shown
-
Push one of the buttons and find the parameter you want to change
-
Push both buttons simultaneously until the parameter value is shown
-
Push one of the buttons and select the new value
-
Push both buttons again to conclude the setting

Valve’s working temperature
Without external signal
The working temperature must be set on the basis of one of the following
curves. Find the actuator temperature corresponding to the required
evaporating temperature (push). Set the value in the controller as mentioned
under “Set the valve’s basic temperature reference”.
With external signal
If the valve is to be operated with an external signal, two settings have to
be made. One is as mentioned to the left, and the other determines how much
the signal must be able to raise the temperature in the valve. This value is
also read on one of the following curves.
Set the value in the r06 menu.
If the set value is too low, the valve will not be able to close/open
fully.
Example
CVQ type = 0-6 bar
Refrigerant = R717
A constant evaporating temperature or input pressure to the valve of -9°C (2
bar) is required.
According to the CVQ curve, this will require a temperature in the actuator of
80°C. Set the valve’s basic temperature reference at 80°C.
When the valve has reached its working temperature, it may be necessary to
fine-adjust the setting from the system’s manometer.
