Safety instructions
The following symbols are used in this instruction manual. This
important information concerns personal as well as operational
safety.
"Safety instructions" must be complied with to the letter, to prevent
risks and injuries to individuals and material losses on the appliance.
Danger through 'live' electrical components!
Please note: Turn off the ON/OFF switch before removing the
casing.
Never touch electrical components or contacts when the ON/OFF
switch is in the ON position. This would lead to a risk of electrocution
that may lead to injury or death.
"Note" indicates technical instructions that must be observed to
prevent material losses and equipment malfunctions.
Even when the unit has been shut down, voltage will still be present
at terminals and connections of the EC fans. This means there is
a risk of electric shock that could result in injury or death.
Never touch the EC fans until ve minutes after disconnecting the
power across all poles have elapsed.
Please note
Safety instructions
Service / Repair - Regularly check the perfect function of all electrical equipment.
- Only qualied personnel may remove faults or repair damage.
- Only replace faulty components or equipment with original Wolf
spare parts.
- Observe specied electrical fuse ratings (see specication).
Any damage or loss resulting from technical modications to Wolf
control units is excluded from our warranty.
Please note
Service / Repair
3063527_201308 5
Standards / Regulations
- According to DIN EN 50110-1, only qualied electricians may
carry out the installation and commissioning of the ventilation
control unit and connected accessories.
- Observe all regulations stipulated by your local power supply
utility and all VDE or local regulations.
- DIN VDE 0100 regulations regarding the installation of high
voltage systems up to 1000 V
- DIN VDE 0105-100 Operation of electrical plants
- Use exclusively original Wolf accessories (electric heater coil,
condensate pump, servomotors, etc.), otherwise the Wolf
warranty will be void.
Only use cables that meet local wiring regulations with regard to
voltage, current, insulation material, load etc. Always t an earth
conductor.
Power supply:
An externally accessible, omnipolar isolator must be installed
with the appliance. Power cable, external: 3 x 2.5 mm².
Fuse/MCB protection: 230 V/16 A.
RCD
Only AC/DC-sensitive RCDs of type B with 300 mA rating are
permissible.
Connect the power cable and accessories in accordance with
the wiring diagram provided.
A high leakage current can be expected due to the EC
motors. Ensure that a secure earth connection is in place
before connecting the power supply and commencing
commissioning.
For Austria, the ÖVE regulations and local building regulations
apply.
Installation /
Commissioning
Warnings - Removing, bypassing or disabling of safety and monitoring
equipment is not permissible.
- The system must only be operated if it is in perfect technical
condition. Immediately have any faults and damage that may
impact on safety removed.
The appliance and control unit accessories comply with the
following regulations:
EC Directives
- 2006/95/EC Low Voltage Directive
- 2004/108/EC EMC Directive
EN Standards
- EN 60730-1 Automatic electrical controls for household and
similar use
- EN 60730-2-11 Particular requirements for temperature
sensing controls
- EN 61000-6-2 EMC Immunity for industrial environments
- EN 61000-6-3 EMC Emission standard for residential
environments
Standards / Directives

The control panel is designed for regulating large area ventilation
units with variable speed EC motors.
Other functions
- HR control 0 - 10 V
- CO2-based fan speed matching
- Electric reheater coil: variable control 0 - 10 V
- Room / supply air cascade control or supply air control
- Night ventilation
- Electric preheater coil:
Switching ON/OFF by outside temperature
The control unit can be operated with the programming module
for ventilation units (BML programming module, material number
2744634). The BML programming module can also be used to
program switching times, to modify parameters and to display
fault messages.
The control unit has an eBUS interface and can therefore be fully
integrated into the Wolf control system.
There can only be one BML in any one system (eBUS).
Up to 7 CGL units can be operated with one programming unit.
Please note
Unit description
Unit description
Observe the following information regarding the disposal of faulty
system components or the system at the end of its service life:
Dispose of all components in accordance with applicable
regulations, i.e. separate material groups correctly. The aim should
be the maximum possible amount of basic materials recycled and
the lowest possible environmental impact.
Never dispose of electrical or electronic scrap through household
waste, but recycle it appropriately.
Generally, dispose of materials in the most environmentally
responsible manner according to environmental, recycling and
disposal standards.
Disposal and recycling
The ventilation unit is designed for air intake temperatures between
-20 °C and +40 °C. Only store the ventilation unit in dry conditions
at an ambient temperature between -25 °C and +55 °C.
Wolf CGL ventilation units are designed to heat and lter normal
air. The use of these units in wet rooms or rooms with explosive
atmospheres is not permissible. Handling very dusty or aggressive
media is not permissible.
Any on-site modication or unintended use of the unit is not
permissible and Wolf GmbH accepts no liability for any damage
caused as a result.
Intended use
3063527_201308 7
Zoning
Zoning When more than one CGL is controlled with one programming unit,
the zone for each appliance must be set using the DIP switches
on the control PCB (in the control panel).
If only one zone is to be connected, the following chapter can
be skipped.
Multiple zones in one
system
The three switches on the left hand side of the 4-position DIP switch
can be used to assign the ventilation unit to a zone.
Up to seven zones are possible in one system.
