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
Structure
Vitocal 100-S is a split air source heat pump, compris-
ing 1 indoor unit and 1 outdoor unit.
Required accessories
Modbus cable between outdoor and indoor unit, 15 m
or 30 m long
Refrigerant circuit
All components of the refrigerant circuit, including the
refrigerant circuit controller with electronic expansion
valve, are located in the outdoor unit, except for the
condenser. Subject to operating conditions, compres-
sor output is matched via inverter control.
The indoor and outdoor units are connected to each
other hydraulically via the refrigerant lines.
Only types 101.B04 to B08
A connection set is available as an accessory for con-
necting the refrigerant lines to the outdoor unit.
For heat pumps with a cooling function, the cooling cir-
cuit is reversed for room cooling.
Overview of heat pumps with allocation of the refriger-
ant used: See chapter "Type overview".
Hydraulics
The high efficiency circulation pump (secondary pump)
installed in the indoor unit pumps the heating water
into the secondary circuit. 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.
