heat pump problems
I bought a home and used my heat pump for the first time yesterday, it heated my place up to 68 degrees the temp I set it for. Then last night it only heated it to 61 and would not go higher, the temp outside last night was roughly 28F and there were frozen patterns around the condenser. This is a day and night heat pump, only 3 or 4 years old. On a side note the thermostat for some reason set itself to 62 I set it back up to 68 but the heat did not come on but the fan was still blowing slightly warmer air than what was in the house, I waited 4 hours and no heat, also the fan on the heat pump was running none stop. Can the heat pump be bad and still heat the house 10 degrees warmer than it is outside? Any help to fix this would be appreciated.

I recommend not using a setback setting on your stat in the heating season.
Most thermostat manuals can be found online.
A heat pump should raise the temp 25 to 30 degrees across the indoor unit without electric heat strips. (your low ambient temperature can affect this)
The heat strips should energize and increase this temperature rise when a demand higher than 2 or 3 degrees is present at the thermostat. (this is a little different with some stats)
Setting the stat for emergency heat with a high demand and measuring the temperature rise across the indoor unit, and reading the KW on your heat strips nomenclature can assist in checking strips.
Calling in a pro to check the high voltage heat strips and refrigerant charge is a good option here.

You have a multistage heat pump and cannot use the posted simple comfort stat.
The heat strips are in your air handler.
An example of the service side...
Heat strips removed from a unit...
High voltage power is always present at the heat strips unless you turn off a breaker, Be Careful.

Sounds like you are describing a split system heat pump.
Heat strips would be in the air handler, in the house if this is the case. Behind four to six 5/16" screws, in the panel that doesn't have copper pipes through it.

I am only out at that house on the weekends due to working in the city, I will have to check this weekend and I will let you know. One other thing, when I was playing around with the stat, I had it set at 68 and switched to the weekend settings and when I switched it back it had set itself back to 62 should it do that when you spin the dial around for different day settings? It makes me think its bad, if not a simpler one would still be better for me.

So last night it was around 55 here outside and my heater pumped out around 96 degrees. So it is definitely hotter than it was last time. My state set itself back down to 62 again last night you recommend a honey well is there a particular model that you could recommend for my system, something very simple to use would be great.

Houston204.,
I figure you don't mind moi step in here real quick.,
Now to OP .,
Take a quick look at the thermosat cable or at the thermosat itself and count how many wires you have in there now due with two stage thermosat may need at least 7 conductors instead of 4 or 5 conductor verison.
Merci.
Marc

Here the photo what he try to upload .,

The number of conductors I counted is 5
I really doubt that will work with aux heat system it have to be 7 so Houdson can you confirm this one to make sure due I am used to 7 or 9 conductor set up.
Merci.

I do not see a common wire, so the multistage heat pump stat will need batteries unless you want to pull wire.
White = heat strips
blue = fan
yellow = compressor
Rh & Rc = 24 volt power
brown = reversing valve for cooling
stage 1 heat = red to blue and yellow
2 stages of heat = red to blue, yellow and white
