System Manager Override Search
NOTE: In order for the Override Search to work, a Loop
Search must be performed fi rst. See page 20 for de-
tails.
When a space sensor with override option is used with any VAV/Zone
Controller or Unit Controller, the System Manager can determine
and report any controllers that are currently operating in an override
condition. This function requires that a MiniLink PD is installed on
each loop where the controllers may be located. The MiniLink PD
must be confi gured to allow for “Alarm Polling” for each controller
that Override Polling Enabled is desired for this function to work. See
the MiniLink PD programming section on page 79 of this manual
for setting information.
