Cleaning and care

▶ If required, wipe the enclosure with a damp cloth. Never
use chemically aggressive or acidic cleaning agents.
2.4

Additional accessories

For precise information regarding suitable accessories, refer to
the catalogue.
• For a mixed swimming pool circuit:
– Mixing valve actuator; connection to VC1 (follow the
technical documentation of the installed heat pump for
the correct positioning of the mixer)
– Swimming pool temperature sensor; connection to
TC1.
Installation of additional accessories
▶ Install the additional accessories in accordance with legal
requirements and the instructions supplied.
3 Installation
DANGER: Risk of electric shock!
▶ Before installing this product: completely
disconnect heat appliances and all other
BUS nodes from the mains voltage.
▶ Before commissioning: fit the cover
( Fig. 14, page 55).

3.1 Installation
▶ Install the module on a wall (
on a mounting rail ( Fig. 6, page 53).
▶ When removing the module from the mounting rail, refer to
Fig. 7 on page 53.
▶ Install the swimming pool temperature sensor TC1
( Fig. 1 [3], page 51) in a suitable place (
page 57).
3.2

Electrical connection

▶ Observe current regulations applicable to power
connections, and use at least cable type H05 VV-...
3.2.1 Connecting the BUS connection and temperature
sensor (extra-low voltage side)
▶ If the conductor cross-sections are different, use the
junction box to connect the BUS nodes.
▶ Connect BUS nodes [B] via junction box [A] in star
( Fig. 12, page 55) or via BUS nodes with 2 BUS
connections in series (
If the maximum total length of the BUS
connections between all BUS nodes is
exceeded, or if the BUS system is realised as a
ring structure, the system cannot be
commissioned.
Maximum total length of BUS connections:
2
• 100 m at 0.50 mm conductor cross-section
2
• 300 m at 1.50 mm conductor cross-section
▶ All low voltage leads must be routed separately from cables
carrying mains voltage to avoid inductive interference
(minimum separation 100 mm).
▶ In the case of external inductive interferences (e.g. from PV
systems), use shielded cables (e.g. LIYCY) and earth the
shield on one side. The shield should be connected to the
building's earthing system, e.g. to a free earth conductor
terminal or water pipe, and not to the earth connecting
terminal in the module.
When sensor leads are extended, apply the following lead
cross-sections:
• Up to 20 m with 0.75 mm
section
• 20 m up to 100 m with 1.50 mm
▶ Route cables through the grommets provided and connect
them as shown in the connection diagrams.
