However need the blower to kick on when the circulator kicks on. Purchased a Honeywell 522ou, 3 heat 2 cool. but the secondary heat is done in stages cannot control it in the way I think it should be.
Would like to choose the furnace to use, or if one doesn't kick on the backup propane will turn on. Open to suggestions! I really like the choice so if something breaks down there is very little to do to switch between furnaces.
You have exactly what you wanted...wire that stat as a Heat Pump, and make the propane be the "Emergency or Auxiliary Heat"
AA 130 will be your 1st stage compressor and the stat will lock it out as soon as in Emergency Mode.
The Fan will run when required while in Emergency.
You are correct...don't wire anything to the 2nd stage as it just "boosts" to the 1st stage output.
