There is a battery inside the thermostat. No one seems to know about this battery. If the battery is dead thermostat won't work. Pop thermostat apart, test battery and replace.battery. I am not 100% sure this is your problem, for your thermostat, but I have come across this problem before. Good Luck Friend.

What type of system do you have?
If you have a heat pump with a reversing valve you will need to set the thermostat settings for a heat pump. Or it can also be the wiring. Check your setting on the thermostat.

The TH8320U1016 thermostat has 2 terminal pins "S1 and S2" that are the ones that are connected to your outdoor sensor, but the TH9320WF003 it doesn't have the "S1 and S2" terminal pins, so I would recommend you the TH6320WF2003 this thermostat is compatible with all system types and with outdoor sensors terminal pins "S1 and S2".

Did you set the minimum and maximum settings on the thermostat?

On a Honeywell thermostat the flashing means that the system is in a delay to turn on the compressor. This is used to protect the compressor from coming on and off too often. The normal delay is about 5 minutes. After that the system should come on. If not there is s problem.

In order to help us help you we will need a little more information. What happens either at the inside unit or at the outside unit after the thermostat stops flashing "Cool"? Any fans come on? Do you hear a "KLUNK"? Any sparks? Please let us know so we can help.
