Can someone please let me know what the function of this unit is?
It is from the power company (WPS) (Wisconsin) and is wired to the A/C unit and it’s exterior electrical disconnect. It has an antenna on the top. The A/C unit was old - 1992 (Bryant)
The label says “Power Systems Energy Management”. It was making a clicking noise about every 5 seconds.
TIA for the Info. Rick
