The appliance is intended solely for installation and
operation in sealed unvented heating systems that
comply with EN 12828, with due attention paid to
CECS 215-2017 and the associated installation, serv-
ice and operating instructions. It is only designed for
heating up heating water that is of potable water qual-
ity.
Intended use presupposes that a fixed installation in
conjunction with permissible, system-specific compo-
nents has been carried out.
The appliance is intended exclusively for domestic or
semi-domestic use; even users who have not had any
instruction are able to operate the appliance safely.
Commercial or industrial usage for a purpose other
than heating the building or DHW shall be deemed
inappropriate.
Any usage beyond this must be approved by the man-
ufacturer in each individual case.
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 use (e.g. if the
flue gas and ventilation air paths are sealed).
Product information
Vitovalor PT2
The Vitovalor PT2 is a micro combined heat and power
unit comprising a fuel cell module and a gas condens-
ing module. To generate heat and power, the
Vitovalor PT2 is operated with natural gas.
Fuel cell module
Integral components such as the reformer, fuel cells
and inverter generate heat and power from the sup-
plied natural gas. Detailed information on the fuel cell
module can be found in chapter "Terminology" in the
Appendix.
Gas condensing module
The integral gas condensing module provides cover for
peaks in demand for heat generation. If the heat gen-
erated by the fuel cell is insufficient, the gas condens-
ing module starts up to ensure heating comfort.
Hydraulics
The heating water is pumped into the secondary circuit
by the integral high efficiency circulation pump.
Depending on the system configuration, the heating
water can be used for central heating and/or for DHW
heating.
Operation
The control unit is integrated into the heat generator
and controls all functions of your system. The control
unit is operated via a 7 inch touchscreen.
A communications module is integrated in the control
unit. This means the system can also be operated
remotely via the internet with an app.
In weather-compensated operation you can select
some functions via a remote control, in room tempera-
ture-dependent operation the same can be done via a
room temperature controller.
Control unit
The Vitovalor PT2 is suitable for heat biased or power-
optimised operation. By means of the integrated
energy manager, the fuel cell can be operated in a
manner optimised for own consumption.
Permissible ambient conditions in the installation room
!Please note
The appliance may develop faults if it is oper-
ated outside the specified temperature ranges.
Ensure that the specified temperature range is
maintained in the installation room.
To avoid malfunctions, ensure a temperature between
+5 and +40 °C.
