Wired room thermostat
with multi-zoning base unit
▪ Installation manual of the wired room
thermostat (digital or analogue) +
multi-zoning base unit
▪ Addendum
book
for
optional
equipment
▪ In this case:
▪ You need to connect the wired
room
thermostat
(digital
or
analogue) to the multi-zoning base
unit
▪ You need to connect the multi-
zoning base unit to the outdoor unit
▪ For cooling/heating operation, you
also need to implement a relay
(field supply, see addendum book
for optional equipment)

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.
