Economizer Controller
ACC-SVN203C-EN 17
ADVANCED
SETUP
SD DMPR POS CLO
CLO
OPN
CLO
Indicates shutdown signal from space thermostat or
unitary controller. When controller receives 24 Vac
input on the SD terminal in conventional mode, the
OA damper will open if programmed for OPN and OA
damper will close if programmed for CLO. All other
controls, e.g., Y1-O, EXH1, etc. will shut
off
DCVCAL ENA MAN
MAN (manual)
AUTO
MAN
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
2
). This operation is not operable with a 2-
speed fan unit
MAT T CAL (c) 0.0 F° (+/-2.5°F) 0.0 F°
Allows for the operator to adjust for an out of
calibration temperature sensor
OA T CAL (c) 0.0 F° (+/-2.5°F) 0.0 F°
Allows for the operator to adjust for an out of
calibration temperature sensor
OA H CAL (c) 0% RH (+/-10% RH) 0% RH
Allows for the operator to adjust for an out of
calibration humidity sensor
RA T CAL (c) 0.0 F° (+/-2.5°F) 0.0 F°
Allows for the operator to adjust for an out of
calibration temperature sensor
RA H CAL (c) 0% RH (+/-10% RH) 0% RH
Allows for the operator to adjust for an out of
calibration humidity sensor
DA T CAL (c) 0.0 F° (+/-2.5°F) 0.0 F° DA T CAL is not available
2SP FAN DELAY (c) 5 Minutes
0 to 20 minutes
in 1 minute
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
CHECKOUT
DAMPER VMIN-HS N/A N/A N/A Positions damper to VMIN position
DAMPER VMAX-HS
(LS) (c)
N/A N/A N/A
Positions damper to VMAX position. With 2-speed
fan units the damper will position to VMAX low
speed fan
DAMPER OPEN (c) N/A N/A N/A
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
DAMPER CLOSE (c) N/A N/A N/A Positions damper to the fully closed position
CONNECT Y1-O (c) N/A N/A N/A
Closes the Y1-O relay (Y1-O)
See “Equipment Damage!,” p. 20
CONNECT Y2-O (c) N/A N/A N/A N/A
CONNECT AUX1-O (c) N/A N/A N/A
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
CONNECT EXH1 (c) N/A N/A N/A Closes the power exhaust fan 1 relay (EXH1)
