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.

Backup heater

WARNING

The backup heater MUST have a dedicated power supply
and MUST be protected by the safety devices required by
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.
