Unit should reset with circuit breaker off/wait/on. Codes are near the end of this manual.

My panel cannot be read.

Hi, you should have a error chart on one of the panels of the unit that will tell you what the 5 blinks mean. It will be pasted on the unit inside some where. Let me know what you find and we will go from there. Merry Christmas,
