Just a question here... My wfco did it too..
I did some work in the camper by removing the top bunk and making shelfs here..
https://forums.goodsamclub.com/index.cfm/fuseaction/thread/tid/29506544.cfmWith that said the PD 4655 is in float mode, and has been since it went into this mode whenever....
I had the heat on during my renovation.( Its 26F here in NJ)
I dont think the voltage drop with 6 led lights on and the furnace went lower then 13.1 -13 volts from my meter reading at the batterys...
It stayed in float mode during my 3 days of putzing around in the camper..
Should it come out easier? Is this normal? My wfco did it too. stayed in float mode..
If I remember correctly the wfco came out of float when I winterized the RV and ran the pump to suck up antifreeze...
Is there an algorithm to this?
Also since I have no way to know what time this goes into equalize mode at the 21 hour mark I have not seen this either..
I don't know how I would know other then being at the right place at the right time...
Thanks all..
