SUPPLY AIR SETPO I NT
Setpoi nt determines where the economizer will modulate the OA damper to
maintain the mixed air temperature.
SeeMenuNote2.

COMPRESSOR LOW TEMPERATURE LOCKOUT
Setpoi nt determines outdoor temperature when the mechanic al cooling
canno t be turned on. Comm only referre d to as the Comp ressor locko ut . A t
or below the se t point the Y1---O and Y2---O will not be energized on the
cont ro lle r.

OA DRY BULB TEMPERATURE CHANGEOVER SETPOINT
Setpoi nt determines where the economizer will assume outdoor air
temperature is good for free cooling; e.g.: at 63_F(17_C), unit will
economize at 62_F (16.7_C ) and below and not economize at 64_F
(17.8_C) and above. There is a 2_F(1.1_C)deadband.

se nsor is co nne c ted. Setp o int for Demand Contro l
Ventilation of space. Above the setpoint, the OA dampers will modulate
open to bring in additional OA to maintain a space ppm level below the
setpoint.
MIN POS 2.8 V 2to10Vdc
VENTILATION MINIMUM POSITION
Displays O NLY if a CO
2
se nsor is NOT connected.
Wit h 2 ---sp eed fan units MIN PO S L (low sp eed fan) and MIN POS H (high
speed fan) setti ngs are required. Default for MIN POS L is 3.2V and MIN
POS H is 2.8V.
VENTMAX 2.8 V
2to10Vdc DCV MA XIMUM DAMPER POSITI ON
Displays only if a CO2 sensor is connected. Used for Vbz (ventilation max
cfm) setpoint. VENTMAX is the same setting as MIN POS would be if you
did not have the CO2 se nsor.
100 to 9990 cfm
increment by 10
If OA, MA RA and CO2 sens ors are connected and DCV CAL ENABLE is
set to AUTO mode, the OA dampe rs are controlled by CFM and di s plays
from 100 to 9990 cfm.
2to10Vdc W it h 2 ---speed fan units VENTMA X L (low speed fan) and VENTMAX H
(high speed fan) settings are required. Default for VENTMAX L is 3.2V and
VENTMAX H is 2.8V.
VENTMIN 2.25 V
2to10Vdc DCV MINIMUM DAMPER POSITION
Disp lays only if CO2 sensor is connected . Used for Va (venti lation min cfm)
se t point . This is the vent ilati on req ui re m e nt for less than maxim um
