Manual Operation of Round Thermostats
Manual Honeywell round thermostats are operated using a simple dial. Users rotate the dial to set the desired temperature. These models often have clearly marked temperature scales for easy adjustments.
Adjusting Temperature with the Dial
The hallmark of the manual Honeywell round thermostat is its intuitive dial for temperature adjustment. Users can effortlessly change the temperature by rotating the circular dial to the desired setting. The dial provides a tactile experience, allowing for precise temperature selection. Many models feature raised markings and clicks at every two-degree increment, offering both visual and auditory feedback. This design ensures that users, regardless of their experience, can easily set the thermostat to the desired level. The ease of use and the clear visual representation of the temperature make these thermostats a popular choice for those who prefer a hands-on, straightforward approach to temperature control. This simplicity is a key reason for their enduring popularity over many years, appealing to a broad range of users who value straightforward functionality and ease of operation. The dial makes the process seamless.
Heat and Cool Settings on Manual Models
Manual Honeywell round thermostats typically offer a straightforward selection between heat and cool modes, or heat-only depending on the specific model. These settings are usually controlled by a switch or lever located on the thermostat housing. To activate the heating system, the user would move the switch to the “heat” position. Similarly, to engage the cooling system, the switch would be positioned to “cool”. Some models may also include an “off” position, which completely disables the system. This manual changeover allows for direct control over the heating or cooling function, ensuring the user can effectively manage the system based on their needs. The simplicity of this switch ensures that even those unfamiliar with thermostat operation can quickly and easily adjust the settings. The direct nature of this control is highly valued by those who seek a simple, no-fuss approach to their home’s temperature regulation, and is a key reason for their continued popularity.
Digital Round Thermostats
Digital round thermostats offer non-programmable options with features like a readable display and precise temperature control. Models like the T8775A and T8775C provide single-stage control for 24 Vac systems, with manual changeover.
Features of Digital Round Non-Programmable Models
Digital round non-programmable thermostats, such as the T8775 series, are designed for straightforward temperature management. These models typically feature a clear digital display that shows the current room temperature, alongside the set temperature. They offer precise control, allowing users to adjust settings with ease. The interface is generally simple, with buttons or a dial for temperature adjustments. Many digital models are designed for 24 Vac systems and often include manual heat/cool changeover capabilities. These thermostats are known for their user-friendly design, making them accessible for all users. The non-programmable aspect focuses on immediate temperature control without the need for complex scheduling, ensuring ease of use for those preferring direct adjustment. They are often mercury-free, aligning with modern environmental standards. Some may also include features like fan settings. Their consistent performance and clear display make them a reliable choice for many homes.

Installation of Round Thermostats
Installing a round thermostat involves wiring and mounting the device. Following the instructions in the manual is essential for a correct and safe setup. Proper wire labeling is a must.
Step-by-step Wiring Guide for CT87 Models
The CT87 series, a popular line of Honeywell round thermostats, requires careful wiring. Begin by turning off power at the breaker. Remove the old thermostat, carefully noting the wire positions and labeling each wire using the supplied labels; ignore wire colors and use only letter designations. The CT87 models typically utilize terminals R for power, W for heat, and Y for cooling when applicable. Securely wrap the labels around each wire and pull the wires through the wiring hole on the thermostat’s cover ring. Connect each wire to the corresponding terminal on the new thermostat base. Double-check connections for accuracy. Ensure no stray wire strands are exposed. After wiring, mount the base plate.
Mounting the Thermostat Base and Cover Ring
After completing the wiring process for your Honeywell CT87 round thermostat, the next step involves properly mounting the base and cover ring. First, align the base plate against the wall, ensuring that the arrow located on the cover ring is pointing upwards. Securely attach the base to the wall using the appropriate screws. Once the base is firmly mounted, carefully align the thermostat body with the tabs on the base. Gently push the thermostat until it snaps into place. For models with a cover ring, ensure it is properly aligned with the base. The cover ring is designed to conceal any marks left by the previous thermostat, providing a clean and finished appearance. Finally, restore electrical power to the system.
