Swimming pool heating
Note
■
Swimming pool heating is controlled via EA1 exten-
sion with KM-BUS.
■
Make connections to EA1 extension
only
in accord-
■
A filter circuit pump
cannot
be controlled via the heat
pump control unit.

Power supply
Isolators for non-earthed conductors
■
Install an isolator in the power cable to provide
omnipolar separation from the mains for all active
conductors, corresponding to overvoltage category
III (3 mm) for full isolation. This isolator must be fitted
in the permanent electrical installation in line with
installation requirements, e.g. mains isolator or
upstream circuit breaker.
■
We additionally recommend installing an AC/DC-
sensitive RCD (RCD class B
) for DC (fault)
currents that can occur with energy efficient equip-
ment.
■
Select and size residual current devices to
DIN VDE 0100-530.
Danger
Incorrect electrical installations can lead to seri-
ous injury from electrical current and result in
appliance damage.
Connect the power supply and implement all
safety measures (e.g. RCD circuit) in accord-
ance with the following regulations:
■
IEC 60364-4-41
■
VDE regulations
■
TAR medium voltage VDE-AR-N-4110
