2 A/C CONTROLLER is provided with independent power supply for each AC. Controller can work with any one or both power supplies. Under normal working condition at Power, depending on the Room Temperature & Set points IDFAN1 & ODFAN1 will be started after Fan Startup Delays. Compressor will be On after Cp1 Startup Delay & after Startup Delays of IDFAN2 , ODFAN2 .Cp2 will be started if required ( depending on room temperature ).

If a fault occurs then ALARM indication on the front panel will be ON & the fault is displayed in the fault status also fault is stored in the Fault log history.
