Aux Heat not working normally? (only up 4F in 2 hours)

Well friend that is simple diagnosis: you put some water on floor stand on it reach inside of unit and fill for terminals if they are tight you should be able to do that can you ''moron''

Hello,

(I know very little about this subject, though I've tried to learn a lot in the last 2 weeks)

I have a First Co. 30VDX15-HP heatpump unit in my apt with a Lux TX9100E thermostat.

At night my temperature is set to 62F and to 68F in the morning. After 2 hours it's only up by 4 degrees (to 66F), while the heat is running continuously.

Is this normal or a sign my auxiliary heat isn't working?

The thermostat shows Stage1 + Aux (until it reaches the set temp within

I'm in Columbus, Ohio, so it's cold at night (in the low 10s)

So while it does eventually warm up, this just seems to slow, or is this normal?

Is there a way for me to test this? Should I try to run this in \"Emergency\" mode which, if I correctly understand this, would run it only in Aux mode (w/o Stage

Thanks!
