The LogoMatic heat interface station is not suitable for installation in adjacent recreation rooms
orbedrooms.
An avoidance of sound transmission in and to adjacent walls or rooms must be observed!
Caution:
Do not make any changes to the electrical components, the design of the system orthe
hydraulic components! This would adversely impact on the safe function ofthesystem.
Instructions concerning the place of use:
Before our products are used, they must be checked for suitability for the planned application
inquestion.
In particular for heating systems, please take into account the properties of the heating water
inaccordance with VDI 2035 to protect the heating system and, for domestic water applications,
thewater quality at the place of use.
In the case of critical water qualities, please take suitable measures where necessary (e.g. water
treatment) to prevent functional impairment and/or damage, e.g. corrosion damage.
In particular, please check the permissible limit values, e.g. electrical conductivity, the pH value,
theGerman hardness level and the ammonium concentration.
Furthermore, in Germany all applicable norms, regulations and guidelines specific to the federal
states must be taken into consideration, alongside the instructions in the applicable installation
andoperating manuals.
Further information can be found in the download section of www.flamcogroup.com.

1.3 Information on hazards
The safety and warning information draws attention to residual hazards that cannot be avoided
due to the design and construction of the device. Please always observe the measures shown
foravoiding these hazards.
Never alter or modify the station by yourself. Such work may only be carried out by qualified
specialist personnel. This also applies to the electrical installation.
When the system is in operation, water-carrying components will be hot. Touching
these system components can lead to scalding. The interface station and its heat-
carrying components are mostly equipped with permanent insulation. This insulation
not only prevents unnecessary thermal losses but also protects against accidental
contact and burns. The insulation must therefore only be removed for maintenance
orrepair purposes and replaced correctly on completion of such work.
Warning: For some components and station variants, no insulation is fitted at the factory. You must
therefore take extra care to avoid accidental contact.
The system is operated using hot, high-pressure water, which can cause scalding on contact.
Youshould therefore open the bleed or drain valves carefully and not work on pressurised parts.
The control components (controller, pumps, etc.) are powered by mains voltage.
Therefore, always ensure the station is disconnected from the mains supply
when carrying out any maintenance orrepair work. Secure the system against
unauthorised operation.
Life-threatening electric shocks can be caused by spray or splashing water. Escaping water can also
render the safety devices inactive.
Any changes made to the station that have not been authorised by the manufacturer will invalidate
any warranty claims.
Residual hazards:
The equipment has been built according to the state of the art and in accordance with recognised
safety regulations. The following residual hazards may arise during installation, commissioning,
maintenance and disassembly:
Warning: Risk of scalding from high media temperature
• Work particularly carefully.
• Use safety clothing (e.g. heat-resistant protective gloves).
• If necessary, surfaces must be thermally cleared before commencing work.
• Use stipulated tools.
Hazard: Risk of injury from electrical voltage
• Only instructed, qualified electricians are permitted to work on electrical equipment.
• Electrical installation spaces must always be kept locked.

Manual LogoMatic G2

1.4 What to do in the event of breakdown or leaks
• Close media lines using the appropriate valve.
• Contact a suitably trained expert or customer service of the manufacturer.
The device will only be cleared for operation again when the trained engineer has remedied the
fault and restored the device to its intended condition.
1.5 Spare and wear parts
All spare and wear parts used must correspond to the technical requirements defined by Meibes
System-Technik GmbH. This is guaranteed only with genuine spare parts. The manufacturer is not
liable for damage caused by the use of unapproved spare and wear parts or ancillary materials.
Appropriate spare and wear parts can be found in the other applicable documents.
1.6 Requirements on trained engineers
A trained expert must have undergone advanced technical training and have suicient experience
to independently perform complicated tasks or work associated with residual hazards. Such
experience will in each instance refer to a specialism, e.g. maintenance, working on electrical
systems, systems mechanic for sanitary, heating and air conditioning technology. In preparation
forimpending work, a trained expert must be able to correctly estimate the feasibility, risks and
hazards as well as the equipment required. A trained expert is expected to be able to understand
complex and minimally detailed plans and descriptions and to use appropriate means to obtain
anymissing and essential detailed information. The trained expert must be able to restore and
check the intended condition of a system. A worker can be a trained expert in several fields.
For work on the electrical equipment, only trained electricians according to DGUV regulation 3 may
be used.
1.7 Liability
We reserve all copyrights to this document. Misuse thereof, in particular reproduction or disclosure
to third parties, is prohibited. These installation and operating instructions must be given to the
customer. The technician carrying out and/or authorising the work (e.g. installer) must explain the
functioning and operation of the system to the customer in a readily comprehensible way.

We reserve the right to change designs and technical specifications of our products.

2. Functional description
The electronically controlled LogoMatic G2 heat interface stations provide a residential station
with domestic hot water and heating. The domestic water is heated via a stainless-steel plate
heatexchanger and electronic control valves based on the continuous flow principle. The station
must simply be connected to the flow and return lines and the cold water line.
The integrated controller is operated at 230 V / 50 Hz. The mains fuse is 10 A.
Fig.: Example

LogoMatic G2 MC-UC-
DHWC station with
mixed HC and optional
STM and ETS
Note concerning LM G2 Weather-driven heating circuit control via optional external temperature
sensor (ETS). STM with electrothermal actuator can be ordered as an optional extra. (see chap. 4.3.1)
A dierential pressure regulator in the station allows for hydraulic balancing of the heating circuits.
The zone valve integrated in each device also permits adjustment of the dwelling heating circuit.
Installing a living space or reference room controller (option) allows the independent operation
ofthe dwelling heating circuit.
Adaptors for water meter and heat flow meter (L = 110 mm, 2 x 3/4" MT) are included in the scope
ofsupply of each station.
Note: Additional accessories or options can be found in the current price list (ETS, STM etc.)
Description of the hot water preparation process:
Heating takes place at a preset control value (50 °C; with circulation 60 °C). The control value can
beadjusted as required by the factory customer service team.
If the flow meter identifies a draw-o, the hot water preparation is adjusted to the preset setpoint
value via the control valves.

4.1 Optional heat meter installation
The heat meter may only be installed once the entire heating system has been flushed through.
LogoMatic G2 stations are fitted with an adaptor (L = 110 mm, 2 x 3/4") for a heat meter which must
be removed before the heat meter is installed.
The corresponding instructions for the HFM must be followed.
Procedure:
1. Close all shut-o valves "A" in the station (if present).
2. Lower the system pressure by opening bleeding device "B". WARNING: Water may leak from
thesystem.
3. Release the screw fittings on adaptor "C". WARNING: Water may leak from the system. (The
station can be drained using bleeding device "B" below or the BFD ball valves, where installed.)
4. Remove the adaptor and insert the heat meter and screw in place. NOTE: Observe the direction
of flow, use seals.
5. Remove the M10x1 plug at "D" and screw in and seal the heat meter supply sensor.
6. Once the work is complete, re-open the shut-o valves and use the bleeding devices to bleed
the station. Perform a leak-tightness check.
