This product is designed to control two Air Conditioners(A.C. or AC) simultaneously. The industry standard AVR Micro-Controller is the heart of this system. Control over the ACs are performed according to some parameters like temperature, phase voltage, phase current, swapping time etc. User can set or view various parameters like current temperature, phase current, phase voltage, temperature set-point, high room temperature, swapping time, AC trip current, A.C. last trip reason etc. through a 16 x 2 character LCD panel and a status indication panel will help user quickly monitor the status of the ACs. An alarm system generates respective alarm for FMC if any error occurs in the operation. This system keeps the information of last AC trip reason and the overload current at which the Air Conditioner (A.C.) was last tripped in a nonvolatile memory for up to 100 years or the next trip occurs. This devise is fully compatible with VOLTAS SENSICOOL Air Conditioners (ACs) used in the shelter of a mobile tower.
