7-2. Night Setback Control
The Night Setback Control function (hereafter abbreviated as Setback Control) prevents indoor condensation by performing heating operation automatically when the room temperature goes outside of the specific range during the night. Click [Functions 3] in the menu bar, and then click [Night Setback Control] to access the Night Setback Control settings screen.
Heating operation starts when a given group is stopped and the room temperature drops below the specified minimum temperature.
Note: The Setback Control function also prevents excessive temperature rise by performing cooling operation automatically when the room temperature goes outside of the specific range. Cooling operation starts when a given group is stopped and the room temperature rises above the specified maximum temperature.
Note: If the room temperature is measured by the return air temperature sensor on the air conditioning unit, the measured value may not be an accurate representation of the temperature in the room, especially when the air conditioning unit is stopped and the room air is stagnant. When this is the case, use an external temperature sensor (PAC-SE40TSA) or remote controller sensor to measure the room temperature.
Note: The Night Setback Control may not be accessible if logged in as a building manager.

(1) Select [Use] and set the time period in which Setback Control is performed.
Note: When [00:00 - 00:00] is selected, Setback Control is active for 24 hours.
(2) In the [Temperature range] section, set the maximum and minimum temperatures for each group.
For example, if [Setback Control Period] is set to [01:00 - 05:00] and [Temperature range] is set to [12°C - --°C] ([53.6°F - --°F]), heating operation starts automatically when the room temperature drops below the set temperature 12°C (53°F) between 1:00 and 5:00. When the Setback Control ends at 5:00, the set temperature returns to the original setting, and the operation stops.
Note: The air conditioning units in the heating operation will stop and the set temperature will return to the original setting when the Setback Control period is over or the room temperature rises to the minimum temperature plus 3°C (5.4°F). Likewise, the air conditioning units in the cooling operation will stop and the set temperature will return to the original setting when the Setback Control period is over or the room temperature drops to the maximum temperature minus 3°C (5.4°F).

Up to 150 Interlock Control settings from No.1 through No.150 can be set. The Interlock Control verifies the state changes in an ascending order of No.1 to No.150 every three to five seconds. When the interlocking conditions are met, the interlocking action commands will be issued to the output units.
By making the interlocking condition settings (input category, input states, and input units) and interlocking action settings (output unit type, actions, and output units) for each Interlock Control setting, the operation of the output units can be interlocked with the operation of the input units.
Caution:
Before using the Interlock Control function, you must agree to the following.
1. This function must not be used for disaster prevention or security purposes unless a backup device is provided in case of failure of this function. (This function should never be used in the way that would put people's lives at risk.)
2. The interlocking action settings that are not supported by the interlocked output units must not be made
