Safety1
1.3 Standards, regulations and directives
1.4 Key to symbols
Two levels of danger are identified and signified by the following
terms:
USER NOTE
Observe all regulations and standards applicable to installation
and operation of the system in your country.
USER NOTE
All electrical components must be approved for the USA and
Canada!
This product has been tested and certified and meets
applicable standards for the US and Canadian markets.
WARNING!
RISK OF LIFE
Identifies possible dangers emanating from a product that might
cause serious injury or death if appropriate care is not taken.
CAUTION!
RISK OF INJURY/
SYSTEM DAMAGE
Indicates a potentially dangerous situation that could cause minor
or moderately serious injuries or damage to property.
USER NOTE
Tip for optimum use of equipment and adjustment as well as
useful information.

Safety 1
1.5 Please observe these notes
The FM443 function module has been designed and built in
accordance with currently recognized standards and safety
requirements.
However, damage resulting from improper service work cannot be
completely prevented.
Before starting service work on the FM443 function module read
these service instructions carefully.
WARNING!
RISK OF LIFE
due to electric shock!
zThe installation, electrical wiring, commissioning, electrical
connection, as well as maintenance and repairs must only be
carried out by a trained contractor who adheres to all current
technical regulations and requirements.
zThe local regulations must be observed.
WARNING!
RISK OF LIFE
due to electric shock!
zMake sure that all electrical work is carried out by a trained
contractor.
zBefore opening the control panel: isolate all poles of the power
supply and secure against accidental reconnection.
WARNING!
RISK OF LIFE
due to electric shock!
The risk of voltage transfers between the line voltage (120 V) and
the low voltage wiring through accidental loosening of the wires at
the terminals must be prevented.
zTherefore secure individual cables together in bundles (e.g.
with cable ties) or strip off only a minimum of the outer
insulation.

1.6 Disposal
zElectronic components do not belong in household waste.
Dispose of defunct modules correctly through an authorized
disposal site.
CAUTION!
RISK OF INJURY/
SYSTEM DAMAGE
due to operator error!
Operator errors can cause injury and damage to property.
zEnsure that children never operate the appliance
unsupervised or play with it.
zEnsure that only personnel trained to operate the appliance
correctly have access to it.
CAUTION!
DEVICE DAMAGE
through electrostatic discharge (ESD).
zBefore unpacking the module, touch a radiator or a grounded
metal water pipe to discharge any electrostatic charge in your
body.
USER NOTE
Ensure that a circuit breaker is available to disconnect all poles
from the mains power supply. If there is no circuit breaker, you will
need to install one.
USER NOTE
Only use original Buderus spare parts. Damage caused by the use
of parts not supplied by Buderus is excluded from the Buderus
warranty.

Product description 2
2 Product description
You can install only one of the FM443 function modules into one
control panel of the Logamatic 4000 control system.
The main function of the FM443 function module is to integrate a
solar system with one or two solar consumers (e.g. tanks) into an
existing control panel.
Installing the FM443 function module makes the following
functions or connection options available:
–Change the operating mode.
–Integrate a solar consumer "1" (e.g. storage tank).
–Buffer bypass circuit for central heating.
–Tank series circuit.
–Integrate a solar heat meter (WMZ), available as an accessory
from Buderus.
–Integrate a solar consumer "2" (e.g. swimming pool).
–Thermal disinfection of the pre-heat stage.
USER NOTE
Before installing the FM443 function module, check the software
version of the controller module (CM431) and MEC2 remote
control (version 4.17 or higher).
For more information, contact your Buderus wholesaler.
