On the Automatic Transfer Switch, there are two blue buttons. One is a manual test switch. The other has a clock on it and this second one is the exercise set button. Holding it down for 3 seconds will program the unit to exercise without a load for 20 minutes at the same time every week.
I prefer to exercise the test every two weeks and for less than 20 minutes. QUESTION: If I test it manually, will this override the automatic testing that is currently programmed in? Hopefully, yes. Thanks in advance.
