Temperature Difference Controller
The "Temperature Difference Controller" regulates the
circulation pump independently of the water tempera-
ture. This ensures the circulation pump only runs when
the water temperature in the oven is higher than in the
buffer tank.
2 Pt1000 temperature sensors are included in delivery.
These sensors are positioned in the sensor pockets of
the oven's water heat exchanger and buffer tank.
The assembly and installation of the "Temperature
Difference Controller" should be completed in accord-
ance with the separate instructions provided with the
device.

Operation
Permissible fuels
The following fuels are approved:
● Natural shopped wood in the form of billet wood
Inlet to the
buffer tank
Billet wood reaches a moisture content of 10 to 15%
after being stored outdoors for 2 to 3 years (only cov-
ered at the top) and is then ideally suited for heating.
Freshly cut wood has a very high moisture content
and so burns badly. Apart from the very low calorif-
ic value it is also harmful for the environment. The in-
creased condensate and tar formation can lead to fire-
place and chimney sooting.
This diagram shows that the consumption rate with
freshlyfelled wood (calorific value 2.3 kWh/kg) is al-
Return
most twice as high as the consumption rate with dry
from the
wood (calorific value 4.3 kWh/kg).

Caloric value [kWh/kg]
You will only achieve optimum combustion and heat
in an environmentally friendly way with these fuels.
Adding the fuel in small quantities avoids unnecessary
emissions. Clean burning can be identified by the fact
that the firebrick becomes a light colour.
According to the German Federal Immission Control
Act, it is forbidden e.g. to burn the following fuels in
stoves:
● Moist wood or wood treated with wood preserv-
● Sawdust, chippings, grinding dust
● Bark and chipboard waste
● Slack coal
● Other wastes
● Paper and cardboard (except for igniting)
● Straw
