Leaving the red wire connected to the existing tstat, I plan on tapping off the red wire to provide 12-volts to the new tstat. Then I would disconnect the white wire from the existing tstat and connect it to the new tstat"
Does a voltmeter confirm you got 12v to the new Tstat? ISTR on my furnace- only Tstat, the two wires are "positive" from the furnace and are switched by the Tstat. Not sure where "negative" is.
Note the fan switch position. It is confusing that you have a heat pump, but this is for the furnace.
EDIT--the furnace operates its own fan, so not sure what that is about.
Not clear on whether taking the red and white from old Tstat gets you the wires to put on W and R with the new. Also the new has its own battery, does not use 12v from the RV, not sure where that applies in this case.
Here is how the original one is supposed to work --if the wires from that are in cut -out with the heat pump even with that white one removed, not clear what is going on.
