Operation with wall device RFF
Function:
A wall device RFF can be connected to the controller.
With a wall device, it is possible to detect the room temperature, to remotely adjust
the room setpoint temperature and to change the operating mode for a heating
circuit. The settings only apply for the applicable heating circuit.
The bus address of the wall device is used to specify on which heating circuit the
room sensor and the adjustment of the operating mode are to act.
The connection is carried out via the data bus.
Setting the bus address
The address of the RFF is set by means of the rotating encoding switch on the inside
of the wall device in accordance with the subsequent table:
Detection of the current room temperature (room sensor)
The integrated room sensor measures the current room temperature for all room
temperature specific functions and transfers the measured values to the standard
unit every 20 s.
Operating mode adjustment
The desired operating mode is selected with the key (keep pressed approx. 2 - 3
seconds) and indicated by the corresponding LED. As the key is pressed, the
operating mode is adjusted in the following sequence:
AUTOMATIC MODE - HEATING – SET BACK - AUTOMATIC MODE -
.....
After the operating mode has been adjusted, the new operating mode is transferred
to the standard unit. Only the operating mode of the heating circuit to which the RFF
is assigned is adjusted.
