INFORMATION
In case of preferential kWh rate power supply, connect
X11Y to X11YB. The necessity of separate normal kWh
rate power supply to indoor unit (b) X2M/5+6 depends on
the type of preferential kWh rate power supply.
Separate connection to the indoor unit is required:
▪ if preferential kWh rate power supply is interrupted
when active, OR
▪ if no power consumption of the indoor unit is allowed at
the preferential kWh rate power supply when active.
INFORMATION
The preferential kWh rate power supply contact is
connected to the same terminals (X5M/9+10) as the safety
thermostat. It is only possible for the system to have
EITHER preferential kWh rate power supply OR a safety
thermostat.
4.4.4 To connect the backup heater power
supply
CAUTION
If the indoor unit has a tank with a built‑in electrical booster
heater, use a dedicated power circuit for the backup heater
and booster heater. NEVER use a power circuit shared by
another appliance. This power circuit must be protected
with the required safety devices according to the applicable
legislation.
CAUTION
To guarantee the unit is completely earthed, always
connect the backup heater power supply and the earth
cable.
The backup heater capacity can vary, depending on the indoor unit
model. Make sure that the power supply is in accordance with the
backup heater capacity, as listed in the table below.

(a) Equipment complying with EN/IEC 61000-3-12 (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.).
(b) 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
sys
is
less than or equal to Z
max
at the 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
sys
less than or equal to
Z
max
.
