I replaced the batteries in my Honeywell RTH110B thermostat with the air conditioning running contrary to the instructions that I read afterward. I am now getting a blinking snowflake air conditioning symbol but no air. How can I fix this problem? Thanks

Make sure batterys are installed correctly and power turned back on.
Read doc below to see what snowflake means. (time delay for cooling) and set cooling cycles per hour.
