Note If no wind information is present, the Tillerpilot will not enter

Steer To Wind mode.

To select Steer To Wind mode, the unit must be in Auto mode

(press STBY/AUTO). Press and hold the Port ( ) and Star-

board ( ) keys together until a double beep is heard (Fig 3.2).

Both the Port and Starboard LEDs will flash simultaneously

while the pilot is in Steer To Wind mode. To switch back to

Compass mode, simply press and hold the and keys togeth-

er again until a double beep is heard.

While in Steer To Wind mode, the Tillerpilot will lock onto the

current apparent wind angle being sailed. Any course adjust-

ments made will be relative to the apparent wind angle, rather

than the compass heading as when in Compass mode.

Initiating an autotack will turn the boat onto the same apparent

wind angle on the opposite tack. As a safety feature, autotack is

disabled when sailing downwind.

Note Nav mode cannot be selected while in Steer To Wind mode – to

activate, return to Compass mode first.

3.3 Using an external compass

The TP22 and TP32 Tillerpilots will preferentially steer to

external compass heading whenever such information is inter-

faced via the SimNet bus.

The use of an external compass is particularly important on a

ferrous-hulled boat (i.e. steel, ferro cement, etc.), as the hull will

affect the bearing read by the internal fluxgate compass.

On a steel- or ferro-hulled boat, the correct location for the ex-

ternal compass would be on the mast, between 1 and 2 meters

above the deck (Fig 3.3). On a non-ferrous-hulled boat, the

compass should be situated low down, as near the center point

of the boat as possible, but away from any sources of magnetic

interference such as speakers, etc.
