Hand Remote HR20
The HR20 is designed to allow remote opera-
tion of the TP20, TP30 and WP30 Cockpit
Autopilots from elsewhere on the vessel.
To engage the Autopilot, steer the desired
course and then press the STBY/AUTO but-
ton (Fig 2). The LED will light indicating that
the Autopilot is activated. To disengage the
Autopilot, simply press STBY/AUTO again.
While in Standby Mode, the arrowed Port
and Starboard buttons can be used to “power
steer” the vessel using the Autopilot (Fig 3).
In Auto Mode, pressing the Port and
Starboard buttons once will alter course by 1º
in the desired direction (Fig 4). Pressing and
holding the buttons will alter course in 10º
increments.
The Autotack facility allows the Autopilot to
automatically tack the vessel through a preset
angle. Press and hold the TACK button, and
while keeping it held, press the Port or
Starboard button (Fig 5), depending on
which direction the vessel is tacking.
NOTE - If in Sail To Wind Mode, the vessel
will tack onto the same apparent wind bear-
ing, but on the opposite tack. In this mode,
the Autopilot will only allow a tack in the cor-
rect direction, and the facility is disabled if
sailing downwind.
