switch on emergency mode.
In emergency mode, room heating and DHW heating
are provided by another heat source.

access data for the registration and product informa-
tion portal.

Heating system
The heat pump can heat or cool your rooms via the
heating system, and heat your domestic hot water.
Your heating contractor will have installed the system
components required for your building according to
which of these functions you will be using.
Depending on your heat pump type, up to two heating/
cooling circuits may be directly connected to the indoor
unit for room heating and/or room cooling.
If your system has a separate buffer cylinder, your
heating/cooling circuits will be connected to this cylin-
der and will be heated and cooled through it. In such a
system configuration, up to 4 heating/cooling circuits
may be connected.
The heat pump supplies direct heat/cooling only to the
buffer cylinder. Due to the large volume of the buffer
cylinder, your heat pump will run less frequently, but
the runtimes will be longer. This offers greater effi-
ciency and protects your heat pump.
Note
In systems with a separate buffer cylinder, it is not
possible to heat one heating/cooling circuit for room
heating while simultaneously cooling another heating/
cooling circuit for room cooling.
The draw-off points for domestic hot water (DHW) in
the house are supplied via a DHW cylinder. On the
Vitocal 151-A this DHW cylinder is integrated into the
indoor unit. With the Vitocal 150-A, your heating con-
tractor will have installed a separate DHW cylinder.
