Turns on the DCV automatic control of
the dampers. Resets ventilation based
on the RA, OA and MA sensor
conditions. Requires all sensors (RA,
OA, MA and CO

). This operation is not

operable with a 2-speed fan unit.

increments.

5 Minutes

When in economizing mode this is the
delay for the high speed fan to try to
satisfy the call for second stage cooling
before the first stage mechanical
cooling is enabled.
