Is the A/C compressor engaging? If you turn the AC off, does the heat stop? Have you checked to see if there is enough refrigerant in the system?
Take a look through this link and let me know if it helps:
Also, let me know if you can control the temperature from hot to cool with the A/C off.
Let me know.
