The Round was introduced to the public in 1953, when Minneapolis-Honeywell was seeking a new product to increase sales. The T-86 Honeywell Round thermostat—known simply as The Round—was easy to make, easy to use, and easy to identify. Sales to both contractors and homeowners soared.
For most thermostats, the CRC and MAC ID are located on the back of the detachable face plate. For RedLINK products, they are located on the RedLINK Internet Gateway. DATE CODE – This describes the date the thermostat was built.
Many of the traditional round Honeywell thermostats have a CR2450 battery that may need to be replaced. If your thermostat is of this type and needs a new battery, the video should give you an insight into how this is done.
Most household thermostats will last about ten years. As they get older, they start to malfunction and become unreliable.
Batteries are typically used as a backup to retain settings during a power outage. Without batteries, the thermostat can maintain the temperature but might lose customized settings if the power fails.
Quick answer: The ideal house temperature is room temperature, which ranges from 68 to 78 degrees F, though this may vary from season to season. In winter, the average room temperature is generally 62 to 68 degrees, whereas in the summer, the average temperature is 72 to 78 degrees.
Keeping your home at a constant temperature generally means that your HVAC system will run constantly to meet it. This means that your furnace or air conditioner may run when you're asleep, at work, or out of the house. This wastes more energy than the minimal amount that you might save by having it constantly run.
68 to 72 degrees is a temperature range that is not too warm or cool, and is sufficient enough to warm up the home just enough so that everyone is comfortable regardless of the type of clothing they have on.

To further help, many Honeywell Home T-Series thermostats are mounted on a Universal Wall Plate that allows you to change models by simply 'popping' one in place of the other.
Adjust Temperature Setting
To lower the temperature setting, turn the dial counterclockwise. To raise the temperature setting, turn the dial clockwise.
The average lifespan of a Honeywell thermostat is typically around 10-20 years, depending on various factors such as usage, maintenance, and environmental conditions. With proper care and regular servicing, a Honeywell thermostat can last even longer.
If the temperature is set to 74°F but the thermometer shows 78°F, you will have to recalibrate the thermostat to account for this 4-degree deviation. Even with older AC units or furnaces, you might have to recalibrate your thermostat from time to time.
Don't set your thermostat too low
“You have to keep it really low to really get into a health concern," he said. "What you want to do is keep it at a reasonable temperature that's not chilly.” The World Health Organization recommends keeping indoor temperatures between 64 and 75 degrees for healthy people.
The U.S. government Department of Energy (DOE) states that people should set their thermostats to 68 degrees F. This is the optimal temperature for keeping a home comfortable.
Many seniors find 78 degrees to be the most comfortable indoor temperature. Anywhere from 65 to 78 degrees is considered safe.
“Anything under 68 degrees overall is ideal for sleep. If you get too hot in the middle of the night, reduce layers of clothing or sheets, turn on fans, or drink a little cold water.”
According to the Department of Energy1, 78° Fahrenheit is the sweet spot for air conditioners to balance energy savings and comfort when people are at home and need cooling.
Most Honeywell thermostats have a low battery indicator light or display a “Low Batt” message, giving you about 60 days to replace the batteries. Ignoring these signs can lead to more than just an uncomfortable home temperature.
The system has a backup battery to sustain power in case of a power outage. If a separate Cellular communicator is installed, that will be used as a backup to the IP communicator.
If you own a Honeywell thermostat, the blank screen could be an indication of a furnace door that wasn't completely closed. These thermostats are programmed to shut off entirely if a furnace door is open. To rule this out, double-check to make sure your furnace door is fully closed.
