Installation
Installation in boiler
For detailed description of boiler components, see boiler
installation instructions.
Wall mounting
The accuracy of the FW100 is dependent upon the
installation location.
Any radiator in the same room as the FW100 should NOT
have a thermostatic radiator valve fitted.
The FW100 should be installed so that the overall
temperature of the property is monitored, for example,
hallways or landings and not be installed in a living room
or room with supplementary heating.
Installation of outside temperature sensor
Control quality depends on location of the outside
temperature sensor. For installation of the outside
temperature sensor please consult product installation
instructions.
Fitting other accessories
Fit accessories, such as ISM1, according to the legal
requirements and the installation instructions supplied
with them.
Electrical connections
Electrical connection in boiler fascia
Installation of the controller automatically produces BUS
connection via the three contacts.
Electrical connection to wall
The FW100 does not require a 230V mains supply, instead
connection is made via a BUS system on the Heatronic 3
circuit board. All BUS connections are polarity free.
To avoid inductive interference, lay all BUS cables separately
to lines of 230V or 400V (minimum spacing 100mm).
In case of external inductive interference, screened cables
should be used. This ensures that the cables are shielded
from external interference (e.g. heavy current cables,
overhead wires, transformer stations, radio and television
sets, amateur radio stations, microwave ovens etc).
Permissible cable lengths and cross sections for use with
the FW100 are shown in the table below:

Disposal
The disposal of packaging and redundant spare
parts should be carried out in an environmentally
responsible manner.
