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.
