Siemens RDE100.. Room thermostat with Auto Timer, Option External Input CB1N1422en_10
Building Technologies 2019-02-28
The external floor temperature sensor is connected to input X1, and acquires
the floor temperature. If the floor temperature exceeds the parameterized
temperature limit xx ºC (P14 = 1, P15 = 1, P16 = xx ºC), the heating valve is fully
closed until the floor temperature returns to a level below the parameterized limit.
Typical application is rooms (dry floor).
If the application does not require floor heating temperature limitation but instead
uses the external sensor as a source for both room temperature display and
control, the parameters will have to be set as follows: P14 = 1, P15 = 0. A typical
application is the bathroom (wet floor) where a constant floor temperature is
required.
It is not recommended to have only an internal built-in room sensor for floor
heating since there is a potential risk of overheating.
Typical application: Maximum temperature limitation for under floor heating
systems
