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 inuenced by the supply air stream of
unit.
