Program setup - back end protection
Back end protection
Press anywhere on the controller and then open the HEA-
TING SYSTEM menu.
Depending on what sensors has been connected to the
boiler and what program options the system has been
set up with the HEATING SYSTEM menu will appear dif-
ferently. The one illustrated is displayed if one sensor G7
is attached and the programmer is set to a constant flow
temperature.
In the shunt control menu scroll down to BACKEND PROT
and press OK. In the BACKEND PROT menu make sure
that the function is set to YES.
Recommended settings:
Temp G1 min:
60°C
Max flow temp: 20°C
Description of function:
The first parameter (Temp G1 min) is the temperature
within the boiler where the Backend protection function
will be enabled. In the above example the function will be
activated when the temperature drops below
function will then restrict the flow temperature down to
the Max Flow temp which in the above example is set to
20°C. Since the draw of hot water is limited to a minimum
while the backen protection function is active the boiler
temperature (G1) will then rise and when the boiler tem-
peratures reaches 61°C the shunt motor will slowly start
to open again.
Boiler warranty is void if the backend protection function isn´t activated when heating
circuits are connected to the back connections of the boiler.
