4.8. Compressor time settings
The following is a list of all the time parameters used for compressor management.
Time between stop requests with HP prevent active
Parameter C06 sets a stop delay between one compressor and the next, if the high pressure prevention (prevent) function is active.
This applies both in the dead band and in the proportional band.
Minimum compressor ON time
Sets the minimum time the compressors stay on, that is, once activated, must remain on for the time set by this parameter (parameter C01).
Minimum compressor OFF time
Sets the minimum time the compressors stay off. The devices are not started again if the minimum time selected (parameter C02) has not elapsed since the last stop.
Minimum time between starts of different compressors (proportional band)
This represents the minimum time that must elapse between the start of one device and the next. This parameter allows simultaneous starts to be avoided
(parameter C03).
Minimum time between starts of the same compressor
Sets the minimum time that must elapse between two starts of the same compressor.
This parameter limits the number of starts per hour. If, for example, the maximum allowable number of starts per hour is 10, to guarantee this limit simply set a
value of 360 (parameter C05).
