Use LiteEdit online connected to the controller
to check all setpoints and correct the wrong
ones. You have to change at least one
setpoint. If all setpoints are correct, change one
of them back to the original value to recalculate
the checksum. Then use the
Controller -> Reset from init state.
Replace the battery as described in the
Maintenance chapter. Then proceed with
LiteEdit as described in the previous situation.
An alternative way is checking all setpoints
from the front panel. Change at least one of
them and then switch the controller off and on.
