6.2.- Neutral zone mode
WITHOUT FREQUENCY CONVERTER
In this mode, a neutral zone is defined, whose lower limit is the Set Point minus the bandwidth, and whose upper
limit is the Set Point plus the bandwidth. While the reading of probe 1 remains in that zone, no stages or
compressors are connected or disconnected.
If the upper limit is exceeded, the controller activates the different stages/compressors separated by the interval
defined in parameter
t03
(red line) until returning to the neutral zone.
If the lower limit is exceeded, the controller deactivates the different stages/compressors separated by the interval
defined in parameter
t04
(green line) until returning to the neutral zone.
In order to deactivate a stage/compressor, the interval
t01
must have passed, and interval
t02
defines the
minimum interval between starts of the same stage/compressor.
