Challenges and Successe

  • Issue: Air handler 6.1 is not supplied with a filter status per sheet M5.5 detail 2.

          Resolution: LAUSD has accepted a runtime alarm for the filter.

  • Issue: The split system fan coil units are unable to control all needed sequences from the BAS. Only theschedule is being controlled. The setpoint adjustments are from the Mitsubishi Touch Screen only. Thesetpoints for these units are a single setpoint for heating/cooling. The sequence of operations requires aheating and a cooling setpoint (70-74).

          Resolution: Climatec to work with Mitsubishi directly to resolve. LAUSD M&O has accepted thesingle point set. Climated has added a 2 degree deadband for htg/clg to initiate.
