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.
