Installing optional accessories

3.5.1
Installation of electric backup heater
(EKBUxx)
INFORMATION
If the ceiling height is low, the storage tank must be tilted to
install the backup heater when empty. This must be done
before any further installation steps.
The indoor unit provides the option of installing an electrical auxiliary
heater (backup heater EKBUxx). For example, renewable energy
can be used as an additional heat source.
INFORMATION
A separate manual containing instructions about installa-
tion and operation is included with this component.
3.5.2
Installation of the external heat generator
connection set
The connection set for external heat generators must be installed to
control an electrical backup heater or another external heat gener-
ator.
1
Open the housing by removing the screw.
2
Remove additional components from the housing (strain relief
clip, cable tie, grommet).
3
Attach the connection set to the controller housing of the indoor
unit. To do this, insert the hooks (1) of the connection set into
the slots of the controller housing (2); then press the connection
set downwards.

3.5.4
The optional P connection kit for Biv device types allows better ac-
cess for connecting the inflow and return flow lines of a pressurised
solar system or another external heat generator on the storage tank.
The kit contains two thermally insulated corrugated pipes that are
connected to the connections of the storage tank via a union nut. At
the other end of the corrugated pipes there is an adapter for different
connection sizes of the supply and return pipes.
