FBR 1, FBR 2 · Edition 07.10 7
4 Project planning information
4.1 Electrical connection
Terminal for triple-core connecting lead on FBR base, see page
6 (Electrical connection diagrams).
FBR 2
A three-pole Rast 5 plug with screw terminals for connection to
an E8 heating controller or Lago E8 is included with the FBR 2.
Connecting lead
The ohmic resistance of the connecting lead affects the desired
value adjustment and the room temperature measurement.
Example FBR 1: A connecting lead with ∅0.25mm2(telephone
line) and a length of 10 m causes the desired room temperature
to increase by 0.2 °C and the room temperature measurement
to increase by 0.5 °C.
Example FBR 2: A connecting lead with ∅0.25mm
2
(telephone
line) and a length of 10 m causes the desired room temperature
to increase by 0.02 °C and the room temperature measure-
ment to decrease by 0.01 °C.
4.2 Installation
The remote control unit should be fitted in the reference / main
living room of the respective heating circuit for best heating
performance.
With activated room sensor influence on the heating controller,
the radiators and any other devices that give off heat should
be as far removed from the FBR as possible. The FBR should
be fitted to an interior wall in an area not affected by draught
or direct sunlight.
