5.9 Automatic operation “HE OFF”
Functional message: “HE OFF”
= appliance switched off via external controller
= appliance must be switched on again manually via I/O key
= functional values can be called u via the “Menu” key
When it displays this message the appliance is responding to an external
controller. The appliance has been switched off via an external controller
and will automatically be switched on again later by the same controller.
Note: If the appliance is now switched off via the I/O
key or through a class 1 error, it can no longer
respond to the external controller and will not start up
automatically again. Instead the display shows “G
OFF” and eventually the “stand-by dot” or, in the
event of an error, the “stand-by dot” flashing
alternately with the error code.
Tip: Do not switch the appliance off via the I/O key when
using an external controller. The I/O key is only intended
for manual operation or as an emergency switch in the
event of errors.
Note:
When the pellet stove is being controlled externally, for ex. via a heating controller, it is
advisable to clean the burner pot and its holes (combustion air holes) at least once a day and at
the same time check that the burner pot is securely seated (see Chapter 0).
5.9.1 Switching the appliance on via an external controller
The appliance starts up as soon as its “ON/OFF” input receives an
“ON” signal from an external controller. After this the display briefly
shows “ON” and then, for a few seconds, the programme version
installed, for ex. “P3 400”. During these seconds the system checks
whether all functions are o.k. In the event of an error the appliance
does not start and instead display the relevant error message (see
Chapter 0 ff.). If everything is in order the appliance then enters
preheating programme “A” and eventually heating programme
“H”.
Thermal
output
can
also
be
adjusted
in
automatic
operating
mode
by simply pressing the “+” and “-” keys.
With a suitable controller you can also modulate thermal output automatically rather than
adjusting it manually (see ### Modulation via external controller).
5.9.2 Switching the appliance off via an external controller
When the appliance is switched off by an external controller after
being in operation this is indicated by the messages “G OFF” and
“HE OFF” flashing alternately until the end of fan after-run time.
After this the display shows “HE OFF” alone.
