STATUS ECON AVAIL NO YES/NO YES = economizing available; the system can use
Outdoor Air for free cooling when required.
ECONOMIZING NO YES/NO YES = Outdoor Air being used for 1st stage
cooling.
OCCUPIED NO YES/NO 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/ac COOL
HEAT
Displays COOL or HEAT when system is set to
heat pump (nonconventional)
COOL Y1-IN OFF ON/OFF Y1-I signal from space thermostat or unitary
controller for cooling stage 1. ON = 24 Vac on
term Y1-I OFF = 0 Vac on term Y1-I
COOL Y1-OUT OFF ON/OFF Cool Stage 1 Relay Output to mechanical cooling
(Y1-OUT terminal).
COOL Y2-IN OFF ON/OFF Y2-I signal from space thermostat or unitary
controller for second stage cooling. ON = 24 Vac
on term Y2-I OFF = 0 Vac on term Y2-I
COOL Y2-OUT OFF ON/OFF Cool Stage 2 Relay Output to mechanical cooling
(Y2-OUT terminal).
MA TEMP _ _._ ºF -40 to 150 ºF Displays value of measured mixed air from MAT
sensor. Displays --.- if not connected, short, or
out-of-range. Always 3F above MA LO Setpoint.
DA TEMP _ _._ ºF -40 to 150 ºF Displays when Discharge Air Sylk Bus sensor is
connected and displays measured discharge air
temperature. Displays --.-°F if sensor sends
invalid value, if not connected, short or out-of-
range.
OA TEMP _ _._ ºF -40 to 140 ºF Displays measured value of outdoor air
temperature. Displays --°F if sensor sends invalid
value, if not connected, short or out-of-range.
OA HUM _ _ % 0 to 100% Displays measured value of outdoor humidity from
QA Sylkbus sensor. Displays --% if not
connected, short, or out- of-range.
RA TEMP _ _._ ºF 0 to 140 ºF Displays measured value of return air temperature
from RAT sensor. Displays --°F if sensor sends
invalid value, if not connected, short or out-of-
range.
RA HUM _ _ % 0 to 100% Displays measured value of return air humidity
from RA Sylkbus sensor. Displays --% if sensor
sends invalid value, if not connected, short or out-
of-range.
