Normally the holidays will operate in an unoccupied mode or a reduced
schedule mode. There are two start/stop events available on holidays to
match the standard schedule number of events.
Schedule Override
Schedule Override
Enter Override : x
[0=Auto 1=ON 2=OFF]
If you want to force the unit to operate in a continuous Occupied or
Unoccupied mode, select this menu item to activate the desired method.
If a Schedule Override is active, all other methods of schedule control
are ignored. (Push-Button, Internal or Remote)
As you can see on the last line of the display you enter a ‘1’ to run
continuously in the Occupied Mode or a ‘2’ to run continuously in the
Unoccupied Mode.
To restore normal schedule operations, make sure a ‘0’ is entered here.
This override remains in effect until canceled by the user and does not
time-out like the Output Overrides do after 10 minutes of no communi-
cations.
Note: Do not use the Force OFF mode in place of setting all
the week schedules to ZERO if you are using a Remote
Signal for your scheduling since the Override has pri-
ority over the Remote Signal.
Setting Time & Date
Both the Modular Service Tool and Modular System Manager are
equipped with a real time clock chip allowing it to maintain the cor-
rect time. Once the correct time and date are entered, the information
is broadcast globally to all controllers on the entire system. The Sys-
tem Manager will also broadcast this information once every day at
midnight to synchronize all the controllers on the system.
From the main System Manager screen press “Enter” and the follow-
ing screen will appear.
1) Set Time & Date
2) Communications
->) Next Menu
ESC) Exit Menu
Press 1 to enter the Set Time and Date Menu.
For the Service Tool, from the main screen press “Enter” and the fol-
lowing screen will appear.
1) Set Time & Date
2) Communications
3) Energy Saving
ESC) Exit Menu
Press 1 to enter the Set Time and Date Menu.
Programming Times
Although the times are displayed on the Main Screen in a standard 12-
hour format, they are programmed using the 24-hour military format. If
the VAV/CAV controller was configured to use its own Internal Sched-
ules, the Occupied/Unoccupied modes are calculated on the basis of the
current real time clock reading.

Space Sensor Overrides
When a space sensor with override option is used the System Manager
or Modular Service Tool can determine and report any units which are
currently operating in an override condition. This function requires that
a polling device is installed on the loop where the controllers are lo-
cated.
To access the Space Sensor Overrides screen, press the “Override” but-
ton located on the System Manager or Modular Service Tool. A screen
will appear asking you to enter a unit ID. Enter an ID for any active
