Honeywell thermostats are designed to control the heating and cooling systems in your home, making it comfortable and energy-efficient.
Honeywell thermostats are equipped with various symbols that help you understand and operate the thermostat. However, understanding these symbols can sometimes be confusing, especially for new users. In this guide, we will discuss the most common Honeywell thermostat symbols and their meanings.
List of Honeywell Thermostat Symbols & Their Meanings
The fan symbol on a Honeywell thermostat represents the fan mode. It indicates whether the fan is set to “auto” or “on” mode.
If the fan symbol is illuminated, it means that the fan is set to the “on” mode and will run continuously, even when the temperature is not being regulated.
If the fan symbol is not illuminated, it means that the fan is set to “auto” mode, and it will only turn on when the temperature needs to be regulated.
The steady flame icon on a Honeywell thermostat indicates that the heating system is active. When the heating system is on, the flame icon will be illuminated, and the temperature on the thermostat will rise until it reaches the desired temperature.
Flashing flame icon
This can also indicate that the thermostat is in heat mode, but the delay mode is active. The delay mode is a feature on some Honeywell thermostats that prevent the heating system from turning on immediately after it has been turned off.
The delay mode helps protect the heating system from damage and extends its lifespan.
During the delay mode, the flame icon will flash to indicate that the heating system is not currently operating.
The delay time can vary depending on the thermostat model and settings, but it typically lasts for a few minutes before the heating system turns on again.
If you see a flashing flame icon on your Honeywell thermostat and suspect that the delay mode is active, wait for a few minutes to see if the heating system turns on.
If it doesn’t, check the thermostat settings and make sure the delay mode is not set for an extended period. If the delay mode is not the issue, refer to the troubleshooting steps mentioned earlier or seek professional help if needed.

Flashing Snowflake Icon
If you see a flashing snowflake icon on your Honeywell thermostat, it can indicate that the thermostat is in cooling mode, but the delay mode is active.
The delay mode is a feature on some Honeywell thermostats that prevent the cooling system from turning on immediately after it has been turned off.
During the delay mode, the snowflake icon will flash to indicate that the cooling system is not currently operating.
The delay time can vary depending on the thermostat model and settings, but it typically lasts for a few minutes before the cooling system turns on again.
However, if the snowflake icon continues to flash for an extended period or is accompanied by an error code, it may indicate a problem with your cooling system.
Some possible reasons for a flashing snowflake icon include a dirty or clogged air filter, a malfunctioning compressor, or an issue with the refrigerant.
If you see a flashing snowflake icon on your Honeywell thermostat and suspect that the delay mode is not the issue, it’s important to address the problem promptly.
Ignoring the problem may cause further damage to your cooling system or even create safety hazards. Here are some steps you can take to troubleshoot the issue:
- Check the air filter and replace it if it’s dirty or clogged.
- Check the compressor and make sure it’s functioning correctly.
- Check the refrigerant level and make sure it’s not too low or leaking.
- Check the thermostat wires and make sure they are properly connected.
If none of these steps resolve the issue, it’s best to seek professional help from an HVAC technician. They can diagnose the problem and make the necessary repairs or replacements to restore your cooling system to working order.
