Installation Guide
This section provides a comprehensive guide to installing the Honeywell RTH221B1039 thermostat. Follow these instructions carefully for a smooth and successful installation process. Ensure safety precautions are taken.
Battery Installation
Proper battery installation is crucial for the Honeywell RTH221B1039 thermostat to function correctly. Before you begin, ensure you have two new AA alkaline batteries. Open the battery compartment, usually located at the top or front of the thermostat, by gently pressing and sliding the cover. Remove any old batteries, noting their polarity (+ and -) as indicated inside the compartment. Install the new batteries, matching the + and ─ signs to the markings in the compartment to ensure correct polarity. Incorrect battery placement can damage the thermostat. After inserting the batteries, securely close the battery compartment cover until it clicks into place. The thermostat display should power on, indicating successful battery installation. If the display does not turn on, double-check the battery polarity and ensure the batteries are fresh. In some cases, a reset might be necessary after battery replacement; refer to the troubleshooting section for instructions. It is recommended to replace batteries annually to prevent leakage and maintain optimal thermostat performance. Battery leakage can damage the thermostat’s internal components. Always dispose of used batteries responsibly, following local regulations for battery disposal. Consider using rechargeable batteries for environmental friendliness and cost savings, but ensure they meet the thermostat’s voltage requirements. Regularly check the battery level indicator on the thermostat display. A low battery warning indicates that the batteries need replacement soon. Ignoring this warning can lead to unexpected thermostat shutdown and loss of temperature control. By following these steps, you can ensure proper battery installation and maintain the reliable operation of your Honeywell RTH221B1039 thermostat.

Setting the Temperature
To manually adjust the temperature on your Honeywell RTH221B1039 thermostat, simply use the Up and Down arrow buttons located on the front of the device. Pressing the Up arrow will increase the set temperature, while pressing the Down arrow will decrease it. The current set temperature will be displayed on the thermostat’s screen. If you are in a programmed mode, this manual adjustment will override the programmed setting until the next scheduled time period.
To view the currently set temperature without making changes, press either the Up or Down arrow button once. The setpoint temperature will be displayed for a few seconds before reverting to the actual (measured) room temperature. This allows you to quickly check your settings without accidentally altering them.
The Honeywell RTH221B1039 also has a feature to prevent damage to your air conditioning compressor. This feature may delay the activation of the compressor for a few minutes after you set a cooling temperature. This delay is normal and protects your system from potential damage due to rapid cycling.
Remember that the temperature you set should be comfortable for you while also being energy-efficient. Consider using the programmable features of the thermostat to automatically adjust the temperature based on your daily schedule, which can help save energy and reduce your heating and cooling costs.
