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 details.
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 condi-
tion. This function requires that a MiniLink PD is installed on each
loop where the controllers may be located. The MiniLink PD must be
con
fi
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 76
of this manual for setting information.
