Cool min
Minimum cooling setpoint limit
Default value =
54 °F ( 12 °C )
Minimum occupied & unoccupied cooling setpoint
adjustment.
Cooling setpoint range is: 54 to 100 °F ( 12.0 to 37.5 °C )
Pband
Proportional band setting
Default = 3
Adjust the proportional band used by the Terminal Equipment
Controller PI control loop.
Note that the default value of 3.0 °F ( 1.2 °C ) gives
satisfactory operation in most normal installation
cases. The use of a proportional band different than the
factory one is normally warranted in applications where the
Terminal Equipment Controller location is problematic and
leads to unwanted cycling of the unit. A typical example is a
wall mounted unit where the Terminal Equipment Controller
is installed between the return and supply air feeds and is
directly influenced by the supply air stream of the unit.
