Wiring sounds good but make sure furnace uses two transformers one for heat and one for cool if it doesn't then at the tstat put a jumper wire between rh and rc

My fastest century is now 4:47:12. Specialized Tarmac, Bontrager ( I know, Trek but friggin' nice bars!) Blade Race X-Lite, Dura Ace, Kysrium Eilte.

I personally know some pro's, Ironmen and World Cycling Champions. Jordan Rapp (winner Ironman Arizona and course record setter, sponsored by Specialized), Dr. Andrew Coggan, WB (world's cross elitist champion, sponsored my Moots).

Nice having a fellow cyclist around.

Slot or terminal? I think you mean terminal. w1 is where you'd put the heat pump heat or first stage heat (primary) as that is your refrigerant heat from the heat pump. w2 would be where you'd connect electric heat which would be your back up (secondary/auxilary) so second stage heat.

W1 goes to Aux and W2 to E. Your thermostat is not giving you the full comfort your system can provide though. If you provide pictures or the wire color and terminal I can provide you with what you are asking. When you described HP were you meaning air handler instead? I would help if you knew what colors went to each terminal including the HP outside, AH inside. From this I can tell what needs to go where.

Wires coming from the heat pump color and what the book says it's for.

Check the install manual. Should be W1 from heat pump should go to aux. That thermostat isn't able to stage in aux heat, so both W1 and W2 from the heat pump get connected to the aux terminal.

The tstat is for a single stage not 2 stage whet you are describing is your heat pump is a two stage compressor
