Application manual
It is possible to set the type of regulation of the mixing valve between “Minimum ON” and “enabling step” using the parameters:
-
PE10 for the evaporator
-
PC10 for the capacitor.
To use these adjustments, the minimum opening percentage of the mixing valve must be set using the parameters:
-
PE05 for the evaporator
-
PC05 for the capacitor.
If you have chosen the type of control Minimum ON (PE10 / PC10 = 0) the valve will always remain open by a minimum percentage
regardless of the request. If the request exceeds the minimum opening value, the valve will assume the request value.
If you have chosen the type of enabling step regulation (PE10 / PC10 = 1), the output will remain at 0% in increase until the request becomes
greater than the minimum value, then it will be kept at a minimum until the request is it will not go to 0%.
For both the valve analogue outputs, it is possible to set 0-10 V or 10-0 V polarity using the following parameters:
–
PE07
for the evaporator
–
PC07
for the condenser
