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.
