To modify the temperature settings on your CT2800 Programmable Thermostat, follow these straightforward steps. Firstly, increase the temperature by pressing the "Temp Warmer" button, or decrease it by pressing the "Temp Cooler" button. Secondly, use the up and down arrows located on the thermostat's display to pinpoint your desired temperature. Finally, your Honeywell CT2800 will show the updated temperature setting, and your heating or cooling system will automatically adjust. Should you face any difficulties or find the display unresponsive while changing the temperature, consult the troubleshooting section within the CT2800's installation manual for detailed guidance.
