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.MaxClgS

etPt

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
