Description Address Application Description
DO 8 50 2290 Digital output 8 controls a 24 Vac load with an ON or OFF
status.
FAN 50 2273, 2274 Digital output used to control the fan. ON indicates the DO is
energized; OFF indicates the DO is de-energized.
MTR TIMING 51 2273, 2274 Time required for the damper actuator to travel from full
closed to the full open position.
MTR1 TIMING 51 2290 Time required for the Motor 1 actuator to travel from full
closed to the full open position.
MTR2 COMD 52 2290 Value to which the Motor 2 actuator is commanded in
percent of full travel (for use as an auxiliary slave point).
MTR2 POS 53 2290 Current position of the Motor 2 actuator in percent of full
travel (for use as an auxiliary slave point). This value is
calculated based on motor run time. See MTR2 TIMING
(Point 55).
MTR2 TIMING 55 2290 Time required for the Motor 2 actuator to travel from full
closed to the full open position.
DMPR ROT ANG 56 2273, 2274 Number of degrees the damper is free to travel.
DPR1 ROT ANG 56 2290 Number of degrees the damper is free to travel.
DPR2 ROT ANG 57 2290 Number of degrees the damper is free to travel.
MTR SETUP 58 2273, 2274, 2290 Configuration setup code for Motors 1 and 2. This enables
the motors individually and sets each motor to be either
direct or reverse acting.
NOTE: When a motor is enabled, its associated DOs are
enabled.
DO DIR.REV 59 2273, 2274, 2290 Configuration setup code for DOs. Allows the DOs to be
direct or reverse acting (enabled equals energized or
enabled equals de-energized).
CYCLE FAN 60 2273, 2274 YES indicates that the fan should cycle ON and OFF with
the compressor during day mode. NO indicates that the fan
should remain ON constantly in day mode.
Valid input: YES or NO
NOTE: In either case, the fan will cycle during night mode.
FREE CLG ON 61 2273, 2274 Value, in percent, that the cooling loopout must exceed for
free cooling to turn ON.
FREE CLG OFF 62 2273, 2274 Value, in percent, that the cooling loopout must exceed for
free cooling to turn OFF.
CLG P GAIN 63 2273, 2274 Proportional gain value for the cooling temperature control
loop.
CLG I GAIN 64 2273, 2274 Integral gain value for the cooling temperature control loop.
CLG D GAIN 65 2273, 2274 Derivative gain value for the cooling temperature control
loop.
CLG BIAS 66 2273, 2274 Biasing of the cooling temperature control loop.
See CLG LOOPOUT (Point 79).
