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.
