Installing a new Thermostat


I had a Honeywell non-adjustable thermostat in my brand new home. I've installed a new adjustable thermo and want to make sure I've connected everything correctly. Everything seems to be working well, but I'm not sure how this whole heat pump/aux thing works. When the heat kicks in, the air seems to be only luke warm if that, but if I crank the heat up 5 degrees or so the outside unit turns off and a few minutes later turns back on and then I get some nice hot air flowing through the vents. Is this normal? Please advise. Thanks!
Bob

That "nice hot air" you are getting is the result of the aux. heaters kicking in. Most heat pump thermostats have 2-stage capability, and when the set point is more than a few degrees different from the room temp, it will cause the aux heat to come on to make up for that difference.

Bottom line is you don't want that to happen unless you are prepared to pay a much higher electric bill.

Something isn't right somewhere.
The HP shouldn't shut off because you turned up the temp.

If you gently turn up your tstat 1 degree increments over a long time does the HP stay on? It could be turning up your tstat 5 degrees is forcing the aux heat on, and once at set-point the HP takes over.

Cranking it up more than 2 deg. will activate the aux. heat, however, when doing so the outside unit should remain running.
