EXH2 OUT OFF ON/OFF EXH AUST STA G E 2 RELAY OUTPUT
Out p ut of A UX terminal; disp lays only if A UX = EXH2
ON = relay closed
OFF = relay open
ERV OFF ON/OFF ENERGY RECOVERY UNIT RELA Y OUTPUT
Out p ut of A UX terminal; disp lays only if A UX = ERV
ON = relay closed
OFF = relay open
MECH COOL ON 0 0, 1, or 2 Displays st a g e of mechanical co oling that is act i v e .
FAN SPEED n/a LOW or HIGH SUPPLY FAN SPEED
Displays speed setting of fan on a 2 - --speed fan unit.
W(HEATON) n/a ON/OFF HEAT DEMAND STATUS
Displays st a t us of heat dem and on a 2---spe e d fan unit.
SETPOINTS
MAT SET 53_F
(12_C)
38 to 65_F;
(3 to 18_C)
increment by 1
SUPPLY AIR SETPOI N T
Setpoi nt determines where the economizer will modulate the OA damper to
maintain the mixed air temperature.
SeeMenuNote2.
LOW T LOCK 32_F
(0_C)
---45 to 80_F;
(---43 to 27_C)
increment by 1
COMPRESSOR LOW TEMPERATURE LOCKOUT
Setpoi nt determines outdoor temperature when the mechanical cooling
canno t be turned on.
DRYBLB SET 63_F
(17_C)
48 to 80_F
(9 to 27_C)
increment by 1
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 a t 64_F
(17.8_C) and above. There is a 2_F(1.1_C)deadband.
SeeMenuNote3
ENTH CURVE ES3 ES1, ES2, ES3, ES4, or
ES5
ENTHALPY CHANGEOVER CURVE
(Re q uires enthalpy se ns o r opt ion)
Enthalp y boundary “curv e s” for economizing using single entha lp y.
DCV SET 1100ppm 500 to 2000 ppm;
increment by 100
DEMA N D CONTR OL VENTILATIO N SETPOINT
Disp lays only if CO

se nsor is connec t e d . Set p o int for Demand Control
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.
