2. PROPORTIONAL CONTROL MODE
If ALGORITHM parameter is selected as HUMIDIFI:
If the humidity is lower than Set humidity(NOTE1) minus HUMIDITY PARAMETERS PAGE HYST control will
be continuously on. If the humidity is higher than the Set humidity(NOTE1) then, control will be continuously
off. If the measured humidity is between Set humidity(NOTE1) and Set humidity(NOTE1) minus
HUMIDITY PARAMETERS PAGE HYST then, control output will be on for a portion of the HUMIDITY
PARAMETERS PAGE PERIOD.
If ALGORITHM parameter is selected as DRIYING
If the humidity is higher than Set humidity(NOTE1) minus HUMIDITY PARAMETERS PAGE HYST control will
be continuously on. If the humidity is lower than the Set humidity(NOTE1) then, control will be continuously
off. If the measured humidity is between Set humidity(NOTE1) and Set humidity(NOTE1) minus
HUMIDITY PARAMETERS PAGE HYST then, control output will be on for a portion of the HUMIDITY
PARAMETERS PAGE PERIOD.
Process Output rises from 0% to 100% in
HUMIDITY PARAMETERS PAGE PROP RAMP period.
This feature is called output Filter.
If HUMIDITY PARAMETERS PAGE PROP RAMP is zero then
output filter is off.
NOTE1:
if curve is enabled;Set humidity = HUMIDITY from curve + HUMIDITY PARAMETERS PAGE OFFSET;
if curve is disabled;Set humidity = SET VALUES PAGE HUMIDITY +
HUMIDITY PARAMETERS PAGE OFFSET;
