Question about Honeywell TH5220D1003 FocusPRO 5000 Digital Non-Programmable Thermostat, Dual S
My system says it's 72 inside. I have the system set to 'Cool' and 68. Only heat comes out, and after 30 mins, the temperature was at 78.
Make sure the thermostat is set to "cool" mode. Make sure the thermostat is wired correctly and has fresh batteries in it. Check both the thermostat end and the air handler end of the wires. If All this checks out, the problem is most likely in the air conditioner, not the thermostat.

Remove the front cover and check your wiring. r-red=power y-yellow=cool w-white=heat g-green=fan.... r-should be hooked up to r-h and a jumper wire-to rc...!

Many t-stats will not let you go within less than 2 degrees of the heat set point....
Lower the heating set point and then you will be able to lower the cooling setpoint..

Is this a new hvac system? A new furnace can work differently than your old one. Does it shut off after a minute or two or continue to run? If it continues to run then call that professional back and let him fix it. If it shuts down after a minute or two then it is a feature of the new thermostat to squeeze all of the cool it can from the a/c coil and ductwork.Some of them have settings that you can adjust for blower delay on and off, read the manual that came with the t-stat and see if it does.

SOURCE: My A/C is operating outside
With such limited information the following is the most likely problem.
1. The fan outside is running but the compressor is not.
2. The inside air handler blower fan is not working.
3. The system is froze up and not allowing any cold air to come out of the vents.
Hope this helps
