Notes
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
2
operable with a 2-speed fan unit.
Allows for the operator to adjust for an
out of calibration temperature sensor.
Allows for the operator to adjust for an
out of calibration temperature sensor.
Allows for the operator to adjust for an
out of calibration humidity sensor.
Allows for the operator to adjust for an
out of calibration temperature sensor.
Allows for the operator to adjust for an
out of calibration humidity sensor.
DA T CAL is not available.
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.
Positions damper to VMIN position.
Positions damper to VMAX position.
With 2-speed fan units the damper will
position to VMAX low speed fan.
Positions damper to the full open
position. Exhaust fan contacts enable
during the DAMPER OPEN test. Make
sure you pause in this mode to allow
for exhaust contacts to energize due to
the delay in the system.
Positions damper to the fully closed
position.
Closes the Y1-O relay (Y1-O). See

CONNECT AUX1 O energizes the
AUX1-O output. If AUX1-O setting is:
•
NONE — No action taken
•
ERV — 24 Vac out. Turns on or
signals an ERV that the conditions
are not good for economizing but
are good for ERV operation.
•
SYS — 24 Vax out. Issues a
system alarm.
Closes the power exhaust fan 1 relay
(EXH1).
