The controller offers 32 independent pressure calendars. For each pressure calendar; the starting day,
hour and minute, the duration, Start Pressure, and Stop Pressure can be independently configured. Start
Pressure and Stop Pressure cannot be set higher than 0.2 Bar above
Main Pressure High Alarm Limit .
This allows for the compressor to run in the desired day and hour of the week for the desired amount of
time with the desired Start Pressure and Stop Pressure.
If a Pressure Calendar
’s duration is set to 0, it is disabled.
In order for the compressor to operate according to the Pressure Calendar, the Pressure Calendar
Enabled parameter in the Controller Configuration Group must be set to 1.
If the compressor
’s Start Pressure or Stop Pressure has been changed according to a Pressure Calendar
entry, the string
“
SCHLD
” is displayed between the Start Pressure and Stop Pressure on the main
pressure and temperature screen.
If the compressor
’s Start Pressure and Stop Pressure have been changed according to a Pressure
Calendar entry, instead of PWM Set Pressure, the average of Start Pressure and Stop Pressure set in
the Pressure Calendar is used.
