EXH1 OUT OFF ON/OFF EXHAUST ST A G E 1 RELAY OUTPUT
Output of EXH1 terminal:
ON = relay closed
OFF = relay open
EXH2 OUT OFF ON/OFF EXHAUST ST A G E 2 RELAY OUTPUT
Out p ut of A UX term i na l; di s plays only if AUX = EXH2
ON = relay closed
OFF = relay open
MECH COOL ON 0 0, 1, or 2 Displays s t a g e of mec hanical cooling that is active.
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 s tatus of heat dema nd on a 2 ---sp e e d fan unit .
SETPOINTS MAT SET 53_F

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

increment by 1
COMPRESSOR LOW TEMPERA TURE LOCKOUT
Setpoi nt determines outdoor temperature when the mechanical cooling
canno t b e turned on.
DRYBLB SET 63_F

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 at 64_F
(17.8_C) and above. There is a 2_F(1.1_C)deadband.
