Modular Service Tool Override Search
When a space sensor with override option is used with any VAV/Zone
Controller or SA Controller, the Modular Service Tool can determine
and report any controllers that are currently operating in an override
condition on the local loop whose ID (Address) has been entered before
running the search. This function requires that a MiniLink Polling Device
is installed on each loop where the controllers may be located.
To access the Overrides Screen, press < Overrides> from the Modular
Service Tool’s keypad. A screen will appear asking you to enter a unit
ID. Enter an ID for any active controller on the local loop you wish to
search and press
<Enter> . Unlike the System Manager, only the over-
rides on this loop will be searched, not the entire system. The following
screen will appear:

SEARCHING!
After the Service Tool completes its search, it will list the fi rst unit on
the selected local loop that is currently in the override mode. Press the
previous or next button to scroll through all units on the local loop you
have selected that are in the Override Mode.
