Clg Stage Time is an adjustable item used to set a minimum
time period between compressor stage changes .
Clg DB is an adjustable item which sets a dead band around
the discharge cooling set point parameter . For example, if the
discharge cooling set point parameter is set to 55ºF and the
Clg Db parameter is set to 2ºF the dead band around the set
point would be from 56 .0ºF to 54 .0ºF .
Clg Lo OAT Lk is an adjustable item which sets the low
outdoor air temperature mechanical cooling lockout point .
Mechanical cooling operation is disabled when the outdoor air
temperature sensor input falls below this set point .
OATDiff is an adjustable item which sets a differential above
the OAT Clg Lock parameter . Mechanical cooling operation is
re-enabled when the outdoor air temperature sensor input rises
above the OAT Clg Lock value by more than this differential .

Clg Reset is an adjustable item that is used to set the type of
cooling reset to be used .
Min Clg Spt is an adjustable item which sets the minimum
cooling discharge set point for use with a cooling discharge air
temperature set point reset schedule .
Min Clg Spt @ is an adjustable item which sets the value of
the sensor input, selected with the Cooling Reset parameter,
at which the DAT cooling set point parameter is reset to the
minimum DAT cooling set point value .
Max Clg Spt is an adjustable item which sets the maximum
cooling discharge set point for use with a cooling discharge air
temperature set point reset schedule .
Max Clg Spt @ is an adjustable item which sets the value of
the sensor input, selected with the Cooling Reset parameter,
at which the DAT cooling set point parameter is reset to the
maximum DAT cooling set point value .
