3.4 Installation MEIER-BRAKENBERG Touch Controller
Important information!
The MEIER-BRAKENBERG Touch Controller is essential for controlling the Top-
Climate-System. The manufacturer accepts no liability for the installation of a sys-
tem without the Touch Controller.
The MEIER-BRAKENBERG Touch Controller should be installed in a dry, clean and easily ac-
cessible location near the pump unit. For mounting, the cover must be opened and the housing
is fastened with suitable screws through the holes intended for fixation.
DANGER
Warning of electrical hazard!
Touching live parts or parts that have become live due faults, poses a direct risk of death. Dam-
age to the insulation or individual parts can be fatal hazard.

Only electrical specialists are allowed to work on the system
’s electrical equipment.

When working in the electrical equipment always shut off the power and verify safe isolation.

Observe the regulations of VDE (Verband der Elektrotechnik Elektronik Informationstechnik
e.V.) or IEC (International Electronical Commission) and the national accident prevention
regulations for electrical systems and equipment.
The MEIER-BRAKENBERG Touch Controller has a wide voltage input (85-264 V, 50/60 Hz).
The voltage supply is usually made via a multi-core connection cable of the pump unit and must
usually be 220-240 V to supply the valves. Other cables (e.g. from additional modules, pressure
switches, climate computers, etc.) are also inserted into the Touch Controller. Depending on the
pump unit and the additional modules, the appropriate Touch Controller must be selected (for
pump units with frequency inverter, the "LCM vario" version is required).
NOTE
Suitable cable glands must be used to ensure good sealing and strain relief of the cables.
The cables are connected according to the wiring
plans (see chapter 7 "Anschlusspläne/Wiring
plans").
The multi-core cables of the pump unit are labelled
with numbers. In the circuit diagrams, the number-
ing is marked as shown in the adjacent detail. Col-
oured cables are marked accordingly (abbrevia-
tions according to IEC 60757). GNYE
(green/yellow) identifies the protective conductor.
The protective conductors of all components must
be connected to each other!
Important information!
Make sure that the mainboard and the IO-Card are not confused when connecting
the cables. Mainboard and IO-Card are marked in the circuit diagrams. Attention:
Sometimes there is the same name of the terminals on both boards.
