limit

Pband
Proportional band setting
Default is : 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.
