Setpoint Ramp Values for cooling and heating setpoint ramp rates. The setpoint Ramp value ranges between 0-
36 Deg F/Hour.
Ramp rates are used by adaptive recovery algorithm to recover heating and cooling setpoints
from their unoccupied values.
The Ramp Rate decides the rate at which the setpoint will transition from current state setpoint to
Occupied setpoint.
The following network variables are updated with the setpoint ramp.
nciRecovClg.MaxClRmp
nciRecovClg.MinClRmp
nciRecovHtg.MaxHtRmp
nciRecovHtg.MinHtRmp
OAT Ramp Values of Outdoor Air Temperature at which the minimum and maximum setpoint ramp rates are
to be applied.
The setpoint point ramp rates are automatically calculated to be between the min and max ramp
rates as the OAT varies between min and max OAT.
The value ranges between -30 to 120 Deg F/Hour.
The following network variables are updated with the OAT ramp.
nciRecovClg.OTMxClRmp
nciRecovClg.OTMnClRmp
nciRecovHtg.OTMxHtRmp
nciRecovHtg.OTMnHtRmp
Occupancy Setpoint Limits Values for limiting the occupied heating and cooling setpoints. These are the range stops to limit
the occupied setpoint values.
Note that these range stops are also used by TR71/TR75.
The following network variables are updated with the Occupancy Setpoint Limits.
nciWallModCom.MinHtgS
etPt
nciWallModCom.MaxClgSetPt
Space freeze protection
setpoint
The space heating setpoint is shifted to this value when a window is opened.
The following network variable is updated with the Space freeze protection setpoint.
nciSpSpcFrz.tempP
Use wallmodule setpoint
for occupied mode
This field can be used to configure whether the wallmodule setpoint input needs to be used or
ignored.
Note that the Wall Module setpoint is active only when the effective occupancy is Occupied or
Bypass.
The following network variable is updated with the Use wallmodule setpoint for occupied
mode.
nciWallModCom.UseWmStPt
Space temp alarm limits Configure the high and low limits to be used to report a 'space temperature out-of-range' alarm.
The space temp alarm disable delay is the delay from a change to occupied mode.
The following network variables are updated with the Space temp alarm limits.
nciSpcTempAlm.HiLimit
nciSpcTempAlm.LoLimit
nciSpcTempAlm.Delay
