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.
