Prop. band
Default value:
3.0
Proportional Band Setting
Adjusts proportional band used by the Terminal Equipment Controller PI control
loop.
Note: default value of 3.0 gives satisfactory operation in most normal installation
cases. The use of a superior proportional band different than the factory one is
normally warranted in applications where Terminal Equipment Controller location is
problematic and leads to unwanted cycling of the unit. A typical example is a wall
mounted unit where Terminal Equipment Controller is installed between return and
supply air feeds and is directly influenced by the supply air stream of unit.
