2283, 2286 The mixed air control loop output value that is used to
determine OA DMPR POS (Point 62).
2287 The outdoor air damper control loop output valve that is used to
determine OA DMPR POS (Point 62).
2281, 2283, The temperature used as input for the temperature control
2284, 2286, loops. This value will be the same as the value in ROOM TEMP
2287 (Point 4) unless it is overridden.
2281, 2283, The cooling temperature control loop output value in percent.
2284, 2286,
2287
2281, 2283, The heating temperature control loop output value in percent.
2284, 2286,
2287
2281, 2284 The proportional gain value for the auxiliary control loop.
2283, 2286 The proportional gain value for the mixed air control loop.
2287 The proportional gain value for the outdoor air damper control
loop.
2281, 2284 The integral gain value for the auxiliary control loop.
2283, 2286 The integral gain value for the mixed air control loop.
2287 The integral gain value for the outdoor air damper control loop.
2281, 2284 The derivative gain value for the auxiliary control loop.
2283, 2286 The derivative gain value for the mixed air control loop.
2287 The derivative gain value for the outdoor air damper control
loop.
2281, 2284 The biasing of the auxiliary loopout point, AUX LOOPOUT
(Point 77).
2283, 2286 The biasing of the mixed air loopout point, MA LOOPOUT
(Point 77).
2287 The biasing of the outdoor air damper loopout point, OA
LOOPOUT (Point 77).
The active temperature control loop output must be less than this
2281, 2283,
2284, 2286, value to switch between cooling mode and heating mode. Actual
2287 switchover depends on SWITCH DBAND (Point 90) being
exceeded and is subject to SWITCH TIME (Point 86) being
expired.
Valid input: 0 to 100%
2281, 2283, The time, in minutes, that must expire to switch between cooling
2284, 2286, mode and heating mode. Actual switchover depends on the
2287 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
