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 tempera-
ture corresponding to the required evaporating tempera-
ture (push). Set the value in the controller as mentioned
under "Set the valve's basic temperature reference".

All the curves shown are approximate.
Example
CVQ type = 0-6 bar
Refrigerant = R
717
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.

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.

The two curves are shown with the valve's spring setting equal-ling the
factory setting. If the spring setting is changed to a higher pressure, the
curve will be displaced correspondingly to a higher temperature.
