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.

Thermostats have multiple issues when you start checking them against thermometers.

1) the built-in thermometer may not match the set temperature because one or both need calibration. Compare the built-in to an external thermometer and see if there is any adjustment to make them match. Record the setting on the thermostat and the temperature when it starts and stops -- there should be a 1-3 degree range which may be adjustable. The set point should be in the middle of the on-off temperature spread.
2) the thermostat has a heat anticipator setting which may be set poorly -- turning off the heat before it reaches the set point - the fan normally runs for 1-2 minutes after the heat source is off. The anticipator is used to stop heating before reaching the set point as there are still a lot of BTUs coming out during the fan run-down -- usually 1-2 minutes.

Actually the 24 hour time makes it easier to correctly set the thermostat for when you want it to change setting.
