If the heating/cooling system does not respond to your Honeywell thermostat, there might be a problem with the selected mode. Check to see if the thermostat is on the correct mode - heat or cool. Also, verify if the temperature is set lower or higher than the ambient temperature, depending on summer or winter respectively.
Please respond to my effort to provide you with the best possible solution by using the "Acceptable Solution" and/or the "Helpful" buttons when the answer has proven to be helpful.
