29 large packaged AC units are controlled by Johnson FX-05 controllers that were originally managed by a Johnson NAE and Metasys ADS. We replaced the NAE with a Tridium JACE which now manages the field controllers for AC and lighting. The JACE serves graphics for the site.
6 outlying switchboards for carpark and external lighting are integrated into the Tridium system via Bacnet by extending a Can2go zigbee wireless network accross the carpark. 7 wireles mesh controllers carry local schedules and IO points to control the lighting systems where formerly staff had to manually reprogram dozens of timeclocks each daylight savings change.
Can2go was the perfect solution. No wires, embedded timeclocks, BacnetIP and completely ‘open’.
