A recent custom control panel installation for a 20,000 sq. ft. office
building retrofit using Johnson Controls. The control system operates a
4 stage DX air conditioning condenser; 2 remote boilers, mixing valves
and pumps located approximately 200 ft. away in adjoining building;
economizer and exhaust dampers; and interfaced with existing Yaskawa
frequency drives for supply and return blowers.
The left picture shows the old panel with pneumatic devices. Right
picture shows new panel with digital controller and 2 pneumatic
transducers to operate existing pneumatic dampers that were still
functional.
