Description Address Application Description
DO 3 43 2290 Digital output 3 controls a 24 Vac load with an ON or OFF
status. lf Motor 2 is enabled, DO 3 is coupled with DO 4 to
control an actuator.
ELEC HEAT 43 2274 This output controls the contact for the first stage of electric
heat and has a status of ON or OFF.
ELEC HEAT 1 43 2273 This output controls the contact for the first stage of electric
heat and has a status of ON or OFF.
DO 4 44 2290 Digital output 4 controls a 24 Vac load with an ON or OFF
status. lf Motor 2 is enabled, DO 4 is coupled with DO 3 to
control an actuator.
HTG CMP 1 44 2274 Digital output used to control the heating compressor 1.
REV VALVE 44 2273 Digital output used to control the reversing valve.
COOL and HEAT status is indicated for the 24 Vac valve or
relay. The default configuration is energized for HEAT. The
configuration may be reversed in DO DIR.REV (Point 59).
DO 5 45 2290 Digital output 5 controls a 24 Vac load with an ON or OFF
status. lf Motor 3 is enabled, DO 5 is coupled with DO 6 to
control an actuator.
COMPRESSOR 1 45 2273 Digital output used to control the compressor. ON or OFF
status is indicated for the 24 Vac relay.
HTG CMP 2 45 2274 Digital output used to control heating compressor 2. ON or
OFF status is indicated for the 24 Vac relay.
CLG CMP 1 46 2274 Digital output used to control cooling compressor 1.
DO 6 46 2290 Digital output 6 controls a 24 Vac load with an ON or OFF
status. lf Motor 3 is enabled, DO 6 is coupled with DO 5 to
control an actuator.
EHEAT3.CMP2 46 2273 Digital output used to control either compressor 2 or the
third stage of electric heat.
CLG CMP 2 47 2274 Digital output used to control cooling compressor 2.
DO 7 47 2290 Digital output 7 controls a 24 Vac load with an ON or OFF
status.
EHEAT2.CMP3 47 2273 Digital output used to control either compressor 3 or 2nd
stage of electric heat.
DMPR COMD 48 2273, 2274 Value to which the damper motor is commanded in percent
of full travel.
MTR1 COMD 48 2290 Value to which the Motor 1 actuator is commanded in
percent of full travel.
DMPR POS 49 2273, 2274 Current position of the damper motor in percent of full travel.
This value is calculated based on motor run time.
MTR1 POS 49 2290 Current position of the damper motor in percent of full travel.
This value is calculated based on motor run time. See
MTR1 TIMING (Point 51).
