STA TUS
ECON AVAIL NO YES/NO ECONOMIZING AV AIALBLE
YES = economizing available; the system can use outside air for free
coo ling when required
ECONOMIZING NO YES/NO ECONOMIZING ACTIVE
YES = Outside air being used for 1
st
stag e cooling.
NO = Econom izing not act ive
OCCUPIED NO YES/NO OCCUPIED
YES = OCC si gnal received from space thermostat
or unitary cont ro ller.
YES = 24 Vac on termi nal OCC.
NO = 0 Vac on termi nal OCC.

COOL Y1 ---IN OFF ON/OFF FIRST STAGE COOLING DEMAND (Y1 - --IN)
Y1---I sig na l from sp a c e thermo sta t or unitary cont ro ller for Cooling Stage 1.
ON = 24 Vac on terminal Y1---I
OFF = 0Vac on terminal Y1---I
COOL Y1 ---OUT OFF ON/OFF FIRST STAGE COOLING RELA Y OUTPUT
ON = 24 Vac on terminal Y1---O; Stage 1 mechanical cooling called on
