When Should I Select Air vs. Floor when Programming my 4iE Thermostat?

 

When the 4iE thermostat is installed following our manual it has the capability to function off of the installed floor probe or the thermostats built in air probe. The thermostat will only operate from one probe location and the probe that you choose will significantly impact the way that the products function. No matter what probe you operate off of, the temperature readings gathered at both locations will always be displayed on the thermostats home screen.

When the thermostat is set to “Large Temperature” display, the words to the right of the large center number will tell you what probe your floor is operating off of. This will be “air” or “floor”. In the top right corner, the opposite probe temperature reading can be found.

Choosing the Air Probe

If you installed the Warmup system for primary heat in your home operating off of the air probe is going to give you the results you are looking to achieve. When the 4iE is set to operate off of the air probe, the floor heater will come on and off as needed to heat the entire room to your set temperature at the thermostat level.

Choosing the Floor Probe

In many instances, Warmup is installed to take the uncomfortable chill out of the floor. In these situations, our system is most efficient operating off of the floor probe. By selecting to operate off of the floor probe, the temperature gathered at the installation location will trigger the thermostat to turn the heating system on/off.

How to Switch

If you would like to change the probe that your thermostat is operating off of you will select the lock on your 4iE to reveal the three lines that are your main menu. From here, select: settings, advanced settings, heating preference, control air/floor, move to your desired choice, and select “accept”.

No Floor Probe Installed? No problem

Since the 4iE has a built-in air probe there is always an option for operation if the floor probe is not installed. If you do not have a floor probe you can remove the ER1 message from your screen by selecting from your main menu: settings, advanced settings, probes, move floor to “off”, and press “accept” in the bottom right.

You can opt into using the air probe instead of the floor probe if…

  • You are more concerned about trying to achieve a specific air temperature, usually for primary heat
  • You or your installer did not install the floor probe*
  • The floor probe is placed in the floor incorrectly
  • The floor probe is damaged.

Otherwise, we recommend you stick with the floor temperature reading for more accurate programming. Please refer to the instruction manual related to your specific model to find out how to switch between air and floor mode. Contact the Warmup technical department if you need further assistance.
