3.2 Package PL2 for Pellet Boilers with Hot Water Tank and Buffer Storage
This suggestion for a pellet boiler heating system according tosystem–package PL2 shows how to build
an uncomplicated, economical and small pellet heating installation with regulated hot water tank and
buffer storage. With this system, a 4–way mixer as boiler back–end protection is not enough. It should,
therefore, be provided with a Thermomix Valve.
Make sure that the boiler circulation pump (15) and the heating circuit pump (18) match up with each
other correctly. Please also read the section „Fitting the boiler back–end protection“ in our technical
material for this.
We recommend that the Thermomix–Valve and the buffer storage are installed in such a way that they
can be blocked on all sides so that an easier service is possible.
The minimum boiler temperature delimination of the heating electronics must be set to 60o C; the burner–
switch difference to 15oC. Please read the heating electronics instructions to do this.
Before installing the system, please read the operation and assembly instructions of all appliances to
make sure that the boiler control panel sensors do not become mixed up with those of the heating electronics.
The wiring of the system must only be carried out by an electrician; PVC cables must not be
used in the boiler.
The electro–connection is made after the electro–plan to the system package PL2.
