MODE
The SETB CTRL MODE item selects the measurement on
which the control function is based during SETBACK
(Unoccupied) Mode.
If this item is set to:
VelSidewall The controller will control face velocity using a
sidewall sensor.
VelSashPos The controller will control face velocity using a
sash sensor and venturi valve with LOM
feedback.
VelSide+Sash The controller will control face velocity using
both the sash sensor with LOM feedback and a
sidewall sensor.
Flow The controller will control flow using the flow
device (see menu item FLOW DEVICE).
FixedPos The controller will hold the damper or venturi
valve at a fixed percentage at all times during
SETBACK Mode, while ignoring the measured
face velocity or flow for control purposes. All
SETBACK-related alarms are still active with
this configuration, unless set to OFF.
NOTE: To shutdown a fume hood with the Model FHC50
controller, set the SETB CTRL MODE item to
FixedPos and the SETBACK POS item to 0%.
