Common Thermostat Alerts and What They Mean
May 15th, 2023 by bspalding
Your thermostat is an integral part of your HVAC system. Sometimes, your thermostat will flash a code that indicates that it needs something. It is important to know the meaning of these codes to know how to address the issue.
Common Thermostat Codes
There are several common thermostat codes. These include:
- FILT alert. This code’s meaning is a sign that your filter needs attention. This helps you to have a monthly reminder to change your filter. Most thermostats will allow you to set the reminder to where you need it. For example, if you have a filter that you do not have to change as often, you can set up that filter setting.
- UV alert. This code’s meaning is Ultraviolet and when it flashes, it is time to replace your ultraviolet bulbs. The ultraviolet bulbs in your system help to improve your indoor air quality. This code usually is set for an annual alert. In some cases, you only have to replace the bulb every 2 years depending on what type you have. If you cannot replace the bulb yourself, you will need to contact an HVAC professional to do this for you.
- DELAY alert. This alert code will let you know that the system has short-cycled and will have a five-minute delay. This helps to protect the compressor from failure. This can be due to someone turning the system back off and on or if the electricity blinked off.
Keeping Your Thermostat In Functioning Order
Keeping your thermostat working is vital to the operation of your HVAC system. The best way to do this is to check for codes. Make sure that you replace the batteries when needed if it is battery operated. Also, you will want to ensure that you keep your thermostat clean. With a dust-covered thermostat, it can cause the system to not read the temperature. This can cause the HVAC unit to run less or more than it needs to. You will also want to ensure that you have maintenance appointments twice a year. Once in the spring before you turn on the air conditioner, and once in the fall before you turn on the heat. This will help to ensure that your thermostat and heating and cooling system works well.
