Description Address Application Description
SWITCH DBAND 90 2583, 2584 Temperature range in degrees that is compared to the
difference between CTL TEMP and CTL STPT. The
difference must exceed this value for temperature control
mode to change over. Changeover is also subject to the
active temperature control loop output being below SWITCH
LIMIT and SWITCH TIME being expired.
NGT MA CTL {91} 2583, 2584 YES indicates that mixed air control should occur during
night mode. NO indicates that mixed air control will not
occur during night mode.
Valid input: YES or NO.
CTL STPT {92} 2583, 2584 Actual setpoint value being used as input for the active
temperature control loop.
MA STPT {93} 2583, 2584 Setpoint of the mixed air control loop.
EHEAT 2 ON 94 2583 Value, in percent, that the heating loopout must exceed for
the second stage of electric heat to turn ON.
EHEAT 3 ON 95 2583 Value, in percent, that the heating loopout must exceed for
the third stage of electric heat to turn ON.
CAL TIMER 96 2583, 2584, 2590 Time interval, in hours, between the calibration sequence.
AOV 3 {97} 2583, 2584, 2590 Analog output 3 controls a 0 to 10V signal.
LOOP TIME 98 2583, 2584 Time, in seconds, between control loop calculations.
ERROR STATUS {99} 2583, 2584, 2590 Status code indicating any errors detected during controller
power up. A status of 0 indicates there are no problems.
CLG D GAIN 102 2583, 2584 Derivative gain value for the cooling temperature control
loop.
CLG BIAS 103 2583, 2584 Biasing of the cooling temperature control loop.
See CLG LOOPOUT.
HTG D GAIN 104 2583, 2584 Derivative gain value for the heating temperature control
loop.
HTG BIAS 105 2583, 2584 Biasing of the heating temperature control loop.
See HTG LOOPOUT.
