(European/International Technical Standard setting the limits for
harmonic currents produced by equipment connected to public
low-voltage systems with input current >16 A and ≤75 A per
phase).
(c)
This equipment complies with EN/IEC 61000‑3‑11 (European/
International Technical Standard setting the limits for voltage
changes, voltage fluctuations and flicker in public low-voltage
supply systems for equipment with rated current ≤75 A) provided
that the system impedance Z
interface point between the user's supply and the public system. It
is the responsibility of the installer or user of the equipment to
ensure, by consultation with the distribution network operator if
necessary, that the equipment is connected only to a supply with
a system impedance Z less than or equal to Z

To connect the shut-off valve

INFORMATION
Shut-off valve usage example. In case of one LWT zone,
and a combination of underfloor heating and heat pump
convectors, install a shut-off valve before the underfloor
heating to prevent condensation on the floor during cooling
operation. For more information, see the installer reference
guide.
