Descriptor Address Application Description
MA LOOPOUT 77 2283, 2286 The mixed air control loop output value that is used to
determine OA DMPR POS (Point 62).
OA LOOPOUT 77 2287 The outdoor air damper control loop output valve that is used to
determine OA DMPR POS (Point 62).
CTL TEMP 78 2281, 2283,
2284, 2286,
2287 The 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 2281, 2283,
2284, 2286,
2287 The cooling temperature control loop output value in percent.
HTG LOOPOUT 80 2281, 2283,
2284, 2286,
2287 The heating temperature control loop output value in percent.
AUX P GAIN 81 2281, 2284 The proportional gain value for the auxiliary control loop.
MA P GAIN 81 2283, 2286 The proportional gain value for the mixed air control loop.
OA P GAIN 81 2287 The proportional gain value for the outdoor air damper control
loop.
AUX l GAIN 82 2281, 2284 The integral gain value for the auxiliary control loop.
MA l GAIN 82 2283, 2286 The integral gain value for the mixed air control loop.
OA l GAIN 82 2287 The integral gain value for the outdoor air damper control loop.
AUX D GAIN 83 2281, 2284 The derivative gain value for the auxiliary control loop.
MA D GAIN 83 2283, 2286 The derivative gain value for the mixed air control loop.
OA D GAIN 83 2287 The derivative gain value for the outdoor air damper control
loop.
AUX BIAS 84 2281, 2284 The biasing of the auxiliary loopout point, AUX LOOPOUT
(Point 77).
MA BIAS 84 2283, 2286 The biasing of the mixed air loopout point, MA LOOPOUT
(Point 77).
OA BIAS 84 2287 The biasing of the outdoor air damper loopout point, OA
LOOPOUT (Point 77).
SWITCH LIMIT 85 2281, 2283,
2284, 2286,
2287 The active temperature control loop output must be less than this
value to switch between cooling mode and heating mode. Actual
switchover depends on SWITCH DBAND (Point 90) being
exceeded and is subject to SWITCH TIME (Point 86) being
expired.
Valid input: 0 to 100%
SWITCH TIME 86 2281, 2283,
2284, 2286,
2287 The time, in minutes, that must expire to switch between cooling
mode and heating mode. Actual switchover depends on the
active temperature control loop being below the value of
SWITCH LIMIT (Point 85) and exceeding the value of SWITCH
DBAND (Point 90).
Valid input: 0 to 255 minutes
