How do I adjust the temperature on my Honeywell TH5220D thermostat for heating and cooling?

[LaCooper]

Adjusting the temperature on your Honeywell TH5220D non-programmable digital thermostat is straightforward. To set your desired temperature, use the up or down arrow buttons on the thermostat. For heating, set the temperature between 40°F and 90°F (4.5°C to 32°C). For cooling, set the temperature between 50°F and 99°F (10°C to 37°C). It's also important to maintain a temperature difference of at least 3 degrees between your heating and cooling settings if you are using the Auto mode. Finally, make sure the thermostat is set to the correct system mode (Heat, Cool, Auto, etc.) depending on your needs. For detailed information and troubleshooting, consult the user manual that came with your Honeywell TH5220D.
