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.
