Why does my thermostat read a percentage (Regulator Mode)?

The 4iE and 6iE have a Regulator mode that controls the heating in 10-minute cycles.

The regulator setting is only meant for tile floors and regulates the heat of the floor using. This setting uses 10-minute cycles rather than the air/floor sensors. When applied, you will select a percentage and this represents the number of minutes the heat will be on out of every 10-minute cycle. For example, if you select 60%, the heat will be on for 6 minutes, followed by 4 minutes of the system being off. Then, after the 4 minutes, it will activate again for 6 and so on. This will continue until your programmed heating period ends or until you manually turn off the heat.

To access/exit regulator mode:

For the 4iE:

• menu>setting>advanced setting>heater setting>regulator>SWITCH TO OFF by pressing up or down arrow>accept and back out.

For the 6iE:

• menu>settings>advanced settings>sensors and applications>room thermostat>use the scroll wheel to change to the desired setting>accept and back out.
