    Heat Pump w/ Aux Heat - Help replacing Thermostat

    i have an american standard AUY08oR9V3W6 furnace with a 2A6H4030B1000AA heat pump. I currently have a Honeywell VisionPRO TH8000 connected that has recently failed. I decided to install a TH8320ZW as I wanted to play around with z-wave. My problem is that the 8000 controlled the auxiliary heat while the 8320 does not have this option. Is there an easy way to make the furnace control the aux-heat? Thanks in advance for your help and/or comments

    Most likely will not get the specific answer to your question as DIY info is NOT allowed here.

    Meant as sarcasm;

    Why not have the installing company come out and explain it?

    Meanwhile, the National Park Service, administered by the U.S. Department of the Interior, asks us to "Please Do Not Feed the Animals". Their stated reason for this policy "... the animals become dependent on handouts and will not learn to take care of themselves."
