The diagnosis points d.17, d.71 and d.84 are lo-
cated in the 2nd. diagnosis level, see Chapter
9.1.2
7.2.1
Setting the heating partial load
The units are set in the factory to a possible heat load
but not yet to the maximum value. Under diagnosis
point "
d.0
" you can set a value which corresponds to
the required output in the heating system in kW.
7.2.2 Setting the pump overrun time
The pump overrun time for the heating operation is set in
the factory to a value of 5 minutes. It can be set under
diagnosis point "
1
" within the range two minutes to
60 minutes. Under diagnosis point "
d.18
" you can set the
overrun behaviour of the pump to a different mode.
Overrun: After completion of the heat demand the heating
pump continues to run for
the time set under "
d.1
".
Continuous: The internal heating pump is switched
on when the rotary knob for setting the heating feed
temperature is not in the left-hand stop position and the
heat demand is released by an external controller.
Winter: The internal heating pump is switched on when
the rotary knob for setting the heating feed temperature
is not in the left-hand stop position.
7.2.3 Setting the maximum flow temperature
The maximum feed temperature for the heating is set in
the factory to 75 °C. Under diagnosis point "
d.71
" it can
be set to between 40 und 85 °C.
