(11b): Underfloor Heating Control
1
Applicable Systems: Radiant Underfloor heating.
Use this parameter to select the type of control for radiant underfloor heating systems. Radiant underfloor heating systems can
be controlled in three ways:
1. Based on indoor air temperature – This type of control is used to control the temperature depending on the room air
temperature.
2. Based on floor temperature sensor – This type of control is used to control the temperature depending on the temperature
measured by the floor temperature sensor.
3. Based on indoor air and floor limiting – This control type is similar to option ‘01: Indoor air temperature’. The air temperature is
controlled with the added feature to always maintain the temperature of the floor between the Slab Minimum and Slab Maximum
temperatures. This parameter will be skipped if you select any option other than ‘04: Radiant Underfloor Heating’ for the previous
parameter (01b). The different options available for this parameter are listed in the table below:
Table 14: Values for Underfloor Control
Underfloor Heating Control (11b) Default Value
01: Indoor air temperature
02: Indoor air and floor limiting
03: Floor temperature sensor only
01: Indoor air
temperature
Note: Refer to the installation manual of the underfloor heating equipment to install the floor sensor if the control type selected is
‘02: Indoor Air and Floor Limiting’ or ‘03: Floor Temperature Sensor’ only.
