STATUS
ECONO AVAIL NO YES/NO
FIRST STAGE COOLING DEMAND (Y1–IN)
YES = economizing available; the system can use outside air for free
cooling when required
ECONOMIZING NO YES/NO
FIRST STAGE COOLING RELAY OUTPUT
YES = outside air being used for 1 stage cooling
OCCUPIED NO YES/NO
OCCUPIED
YES = OCC signal received from space thermostat or unitary
controller
YES = 24 Vac on terminal OCC
NO = 0 Vac on terminal OCC
HEAT PUMP N/A
COOL
HEAT
HEAT PUMP MODE
Displays COOL or HEAT when system is set to heat pump
(Non-conventional)
COOL Y1—IN OFF ON/OFF
FIRST STAGE COOLING DEMAND (Y1-IN)
Y1–I signal from space thermostat or unitary controller for cooling
stage 1.
ON = 24 Vac on terminal Y1–I
OFF = 0 Vac on terminal Y1–I
COOL Y1—OUT OFF ON/OFF
FIRST STAGE COOLING RELAY OUTPUT
Cool stage 1 Relay Output to stage 1 mechanical cooling
(Y1–OUT terminal)
COOL Y2—IN OFF ON/OFF
SECOND STAGE COOLING DEMAND (Y2–IN)
Y2–I signal from space thermostat our unitary controller for second
stage cooling.
ON = 24 Vac on terminal Y2–I
OFF = 0 Vac on terminal Y2–I
COOL Y2—OUT OFF ON/OFF
SECOND STAGE COOLING RELAY OUTPUT
Cool Stage 2 Relay Output to mechanical cooling
(Y2–OUT terminal)
