The range of functions can be extended with additional
components and accessories.
Intended use presupposes that a fixed installation in
conjunction with permissible, system-specific compo-
nents has been carried out.
Commercial or industrial usage for a purpose other
than central heating/cooling or DHW heating shall be
deemed inappropriate.
Incorrect usage or operation of the appliance (e.g. the
appliance being opened by the system user) is prohibi-
ted and will result in an exclusion of liability. Incorrect
usage also occurs if the components in the heating
system are modified from their intended function.
Note
The appliance is intended exclusively for domestic or
semi-domestic use, i.e. even users who have not had
any instruction are able to operate the appliance
safely.
Product information
Layout
The Vitocal 350-A is an air source heat pump with out-
put-dependent control.
Type AWHI 351.A is installed inside the building. Air
drawn in is supplied to the heat pump via an air duct.
Expelled air similarly leaves the building via an air
duct.
Type AWHO 351.A is installed outside the building.
The hydraulic connection lines are routed below
ground and must be frost-proof.
Hydraulics
To supply the secondary circuit, either two circulation
pumps (secondary pump and circulation pump for cyl-
inder heating) or 1 secondary pump and a 3-way
diverter valve are connected.
On type AWHI, the secondary pump can be built into
the heat pump. The remaining components are instal-
led outside the appliance.
On type AWHO, the hydraulic components for supply-
ing the secondary circuit are installed outside the heat
pump.
Central heating
The heat pump is able to supply up to 3 heating cir-
cuits: 1 heating circuit without mixer and 2 heating cir-
cuits with mixer. The mixer extension kit (accessories)
is required to control the mixer for the second heating
circuit with mixer.
Central cooling
Central cooling results either through a heating/cooling
circuit or via a separate cooling circuit. For this, the
refrigerant circuit is reversed and heat is extracted
from the cooling circuit.
Heat pump control unit
The entire heating system is monitored and controlled
by the integral Vitotronic 200, type WO1B heat pump
control unit.
