Danfoss EFIT 550 - Sensor Usage for Heating Systems; Choosing Heating and Sensor Types; Mandatory Floor Sensor for Wooden Surfaces

When installing the Thermostat EFIT 540/550 you need to
choose the type of heating and thus which sensors should
be used.
Danfoss recommend always to install the fl oor sensor !
Comfort Heating:
• Constant temperature on the fl oor in e.g. bathrooms and
other rooms that are often used with bare feet.
• Install the Floor sensor and choose only the Floor sensor
in Basic Settings.
Total Room Heating:
• Control of room temperature in living rooms etc.
• Install the Floor sensor and choose both Floor sensor
and Room sensor in Basic Settings.
No Floor Sensor:
• A fl oor sensor is not present, and cannot be installed.
• Choose Room sensor only in Basic Settings.
• Be aware that temperature control is less accurate
without the fl oor sensor. Danfoss recommend that a fl oor
sensor is installed.
Do NOT use Thermostat EFIT 540/550 without fl oor
sensor when the heating element is installed on or
beneath wooden surfaces !
