The way it works is that you select it to ON
and then if you want to AUTO, most of the installs will probably be only manual
control, on the current turbo prop aircraft using our system
you manually select mode Lo or mode Hi, mode Lo
is 45 seconds on element A , 45 sec on B and 90 sec OFF, then on
mode Hi is 90 sec on A and 90 sec on B no OFF period.
( hi is for icing below - 16 Deg C.) this is for a
four blade prop on a high performance single turboprop . ( current draw is
25 Amp initially and goes down to about 23-24 depending on the heat cycle.The
annunciator light will confirm a switch over from element A to B and Hi or Lo
cycle.
By connecting your laptop via serial connection you
can program the settings and also do a system diagnostic check etc.

Subject: LML prop heat
Maurits,
You may want to rethink the auto function.
Turning the unit on referencing only temp. will cause the prop heat to
actuated when icing condition do not exist (most of the time). This will
cause a premature failure of the heating elements. For the system to be
effective it must first detect ice or high relative humidly.
