If the boiler does not start up, check that there is a
heating requirement (s
ee page 9
). If there is no heating
requirement but you believe that there should be one,
make sure that the time is set correctly (
page 12
). Next,
check the time programs: the heating circuit, water heating
or the circulation may be outside of the time windows
(
page 16f
). If the circulation is not working, make sure
that the operating mode is set to “Time” (
page 46
).
Finally, have a look at the top line on the display and
make sure that there is a hand symbol under one of
the numbers (
figure on right
). If there is a hand symbol,
the relevant output is set to manual mode and must
be switched to automatic mode (
page 28
).
If the SolvisControl display no longer responds when
you turn the rotary wheel, switch the control off,
wait 20 seconds, and then switch it back on again.
Many problems can be resolved in this way. If there
is a heating requirement but the boiler does not start up,
the boiler may have a malfunction. Check whether it is
switched on and press the unlocking button on the boiler’s
automatic firing system, if necessary. Follow the instruc-
tions in the relevant operating instructions.

the hand symbol disappears.
