Description Address Application Description
HTG P GAIN 67 2273, 2274 Proportional gain value for the heating temperature control
loop.
HTG I GAIN 68 2273, 2274 Integral gain value for the heating temperature control loop.
HTG D GAIN 69 2273, 2274 Derivative gain value for the heating temperature control
loop.
HTG BIAS 70 2273, 2274 Biasing of the heating temperature control loop.
See HTG LOOPOUT (Point 80).
MA P GAIN 71 2273, 2274 Proportional gain value for the mixed air control loop.
MA I GAIN 72 2273, 2274 Integral gain value for the mixed air control loop.
MA D GAIN 73 2273, 2274 Derivative gain value for the mixed air control loop.
MA BIAS 74 2273, 2274 Biasing of the mixed air control loop.
CMP TOTL 75 2273 Number of compressors used by the application.
Valid values: 0, 1, 2, 3
HTG CMP TOTL 75 2274 Number of heating compressors used by the application.
Valid values: 0, 1, 2
EHTG STG CNT 76 2273, 2274 Number of electric heating stages used by the application.
Valid values: 0, 1, 2, 3
CLG CMP TOTL 77 2274 Number of cooling compressors used by the application.
Valid values: 0, 1
CTL TEMP 78 2273, 2274 Temperature used as input for the temperature
control loops. This value will be the same as the value in
ROOM TEMP (Point 4) unless it is overridden.
CLG LOOPOUT 79 2273, 2274 Cooling temperature control loop output value in percent.
HTG LOOPOUT 80 2273, 2274 Heating temperature control loop output value in percent.
ELEC HEAT ON 81 2274 Value, in percent, that the heating Ioopout must exceed for
the electric heat to turn ON.
EHEAT 1 ON 81 2273 Value, in percent, that the heating loopout must exceed for
the first stage of electric heat to turn ON.
CMP1 ON 82 2273 Value, in percent, that the active temperature control
loop output must exceed for compressor 1 to turn ON.
Actual turn on is subject to the CMP MlN OFF (Point 87)
time being expired. lt is also the value, in percent, which
HTG LOOPOUT (Point 80) must go below for the electric
heat (ELEC HEAT 1, Point 43) to turn OFF when only one
compressor is used.
HTG CMP1 ON 82 2274 Value, in percent, that the heating temperature control loop
output must exceed for heating compressor 1 to turn ON.
Actual turn on is subject to the HTG1 MlN OFF (Point 87)
time being expired.
