HVAC Signals
Y, Y2, G, W, W2, O/B 24VAC – Industry standard 24VAC signal
outputs directly control up to 2 stages of Heat and 2 stages Cool
for both Conventional and Heat Pump systems. Auxiliary and
Emergency Heat are also supported.
Economizer Signals
ACT 0-10 VDC Actuator Output – This signal modulates the
damper actuator.
POS 0-10 VDC Actuator Position Input – This signal tracks
damper position.
ENA 24 VAC Enable Output – This signal energizes when the
Economizer is active and can be used to control exhaust fans or
auxiliary economizer equipment.
Variable Speed Fan Signals
AUX 0-10 VDC Speed Output – This signal adjusts the speed
of the fan.
G
24 VAC fan start/stop signal.
