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
Vitocal 200-A is a monoblock air/water heat pump,
comprising 1 indoor unit and 1 outdoor unit.
Refrigerant circuit
All components of the refrigerant circuit are located in
the outdoor unit, including the refrigerant circuit con-
troller with electronic expansion valve. Subject to oper-
ating conditions, compressor output is matched via
inverter control.
For central cooling, the refrigerant circuit is reversed
(only types with designation "-AC").
Hydraulics
The indoor and outdoor units are connected to each
other hydraulically on the secondary side.
The hydraulic components for the secondary circuit are
located in the indoor unit. The heated heating water is
pumped into the secondary circuit by the integral high
efficiency circulation pump (secondary pump). The
integral 3-way diverter valve for "central heating/DHW
heating" changes over between central heating and
DHW heating.
System without buffer cylinder
■
Room heating
The heat pump heats 1 heating/cooling circuit with-
out mixer.
■
Room cooling
The heat pump cools through 1 heating/cooling cir-
cuit without mixer or through 1 separate cooling cir-
cuit.
System with heating water buffer cylinder
■
Central heating
The heat pump heats up to 3 heating/cooling circuits:
1 heating/cooling circuit without mixer and 2 heating/
cooling circuits with mixer
■
Central cooling
The heat pump can only cool either through one of
the max. 3 heating/cooling circuits or through a sepa-
rate cooling circuit.
The heating water buffer cylinder is bypassed
hydraulically by a bypass circuit.
System with heating water/coolant buffer cylinder
■
Central heating
The heat pump can heat up to 3 heating/cooling cir-
cuits: 1 heating/cooling circuit without mixer and
2 heating/cooling circuits with mixer
■
Central cooling
The heat pump can cool through up to 3 heating/
cooling circuits. Central cooling via a separate cool-
ing circuit is not possible.
Heat pump control unit
The entire heating system is monitored and controlled
by heat pump control unit Vitotronic 200, type WO1C.
The heat pump control unit is integrated into the indoor
unit. The indoor and outdoor units communicate via
Modbus.
