REMINDER!
To ensure reliable operation of the heater, it is required to start it once in
30 days on max heating power for 30 minutes including the warm seasons of the
year, when heater is out of operation. This action is necessary to remove any
viscous film sediments on moving parts of the fuel pump. Failure to do so may
lead to premature failure of the heater.
That is why AUTOTERM Comfort Control has a built-in reminder to start the
heater for 30 minutes, if it has been out of operation for at least 30 days.
After 30 days of inactivity since the last start red LED indicators blinks
once every 5 seconds and message is displayed. Accept the start by pressing
the knob once. Decline the start by pressing the “Back” button once. In case
of a decline, this message is repeated if the heater hasn’t been launched in
any of the heating modes.
