> Status: Critical
> Building: E17
> Date: 7/23/2003
> Day: Wednesday
> Time: 7 AM - 12 Noon
> System: Air Handler 3, HW Converter #2 and Exhaust Fans 1 through 8
> Duration: 5 hours
> Reason:
> Control conversions - upgrade.
>
> Effect:
> If it is a mild weather day, the cross connect duct from Air Handler 6
> will be used to supply air to Air Handler 3 while the controls are being
> upgraded. If it is decided the cross connect from AH6 cannot be used then
> a temporary controller will be used to temporary control necessary points
> in order to maintain unit operation. If the temporary controller is used
> there will be only a half hour or less period of no automatic control as
> point wires are transferred from controller to controller. There would be
> the same half hour or less down period when the wires are transferred to
> the new controller.
>
> The temporary controller will be used to operate hot water converter 6
> during the conversion with the same amount of down time as mentioned
> above.
>
> Exhaust fans 1 thru 8 will be put in the Hand position at the motor
> starter.
