I first noticed this back in December when we had some unusually cold weather, in the teens, which is not normal for South Mississippi.* I realize the heat pump switches to auxillary in these conditions but then I started noticing when the heater first comes on the display says HEAT.* After about a minute it switches to AUXILLARY HEAT.* It stays that way about 2 minutes then goes back to HEAT.* This may be normal and I just never noticed it before but what do y'all think.
