Adjusts proportional band used by Room Controller PI control loop.
Default value of 3 gives satisfactory operation in most normal installation cases. The use of a superior
proportional band different than the factory value is normally warranted in applications where Room
Controller location is problematic and leads to unwanted cycling of the unit. A typical example is a wall
mounted Room Controller installed between return and supply air feeds and is directly influenced by
the supply air stream of unit.
