Significance and adjustments
Prop. band
Default is : 3
Proportional band setting. Adjusts the proportional band used by the
Terminal Equipment Controller PI control loop.
Warning: Note that the 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
the Terminal Equipment Controller location is problematic and leads to
unwanted cycling of the unit. A typical example is a wall mounted unit
where the Terminal Equipment Controller is installed between the return
and supply air feeds and is directly influenced by the supply air stream of
the unit.

Pulsed heating
Default Value = Off VDC output configuration. VC3000 series model dependent.
Off = Regular On-Off control for VC350xE models only.
Can be used with 2 & 4 pipes applications.
On = VDC SSR electric heat 10 second pulsed time base modulation for
SC340xE models only.
Can only be used with 2 pipes system only.
Occ Out = VDC Occupancy output follows local device occupancy for
SC3514E model only.
Occupied & Temporary Occupied = Contact closed
Stand-By & Unoccupied = Contact opened
