General
Introduction
The TP10, TP22, and TP32 Tillerpilots from Simrad are suitable for a
wide variety of tiller-steered sailing yachts up to 12 m (39 ft) overall
length.
Combining highly sophisticated electronics with advanced software
and a powerful mechanical drive, they are capable of providing
reliable and accurate steering performance under a variety of
different conditions with minimal current consumption.
The Tillerpilots have been designed so that, while they represent the
state-of-the-art in marine autopilots with many advanced features,
they remain very simple to operate, using only five keys to access all
functions.
Sophisticated functions of the TP22 and TP32 include Steer To Wind
mode and Nav mode (Steer To GPS) using external equipment
linked directly to the Tillerpilots via the SimNet high-speed bus, or
through the built-in NMEA 0183 interface. There is also the option
to operate the Tillerpilots remotely using a remote controller.
To ensure the best results from your Tillerpilot, it is essential that the
unit is installed correctly. Please read this manual thoroughly before
installation.

The SimNet network system
The SimNet system is built around a high-speed bus networking
system, that allows the TP22 and TP32 to be easily interconnected to
Simrad instruments and navigation equipment.
Units are interconnected and powered using a standard single
cable.
Typical SimNet system
The Tillerpilot can receive navigational information from the
chartplotter for Steer To GPS (Nav mode).
It will also accept wind angle data from the wind transducer for
Steer To Wind mode, boat speed data from the Speed instrument,
and heading data from the compass transducer.
Additionally, heading data from the Tillerpilot’s built-in fluxgate
compass can be displayed on any instrument displays capable of
showing compass information.
¼Note: Heading data from the Tillerpilot will only be shown on
instrument displays if there is no external compass transducer
present on the network. Priority is always given to external compass
transducers for heading data.

Operation
General
The Tillerpilots have no power key, and will be ON as long as power
is connected.
The unit powers up in Standby mode indicated by a flashing LED
next to the STBY/AUTO key. The two direction LEDs above the port
() and starboard ( ) keys are always dimly lit, which provides night
illumination for the keypad. All functions are confirmed audibly by a
“beep” and visually by the LEDs, so the status of the unit can always
be confirmed at a glance.
¼Note: The NAV key on the TP22 and TP32 is labeled CAL on the
TP10. Both keys are referenced where applicable.
Standby mode
While in Standby mode, the pushrod can be manually driven in and
out by pressing the arrowed port ( ) and starboard ( ) keys, which
allows “power steering”of the vessel.
Autopilot mode
¼Note: The rudder zero position is captured at first time initiation of
Autopilot mode. This information is however lost if the unit is turned
OFF. Before initiating the Autopilot mode after a power down, you
should ensure that the rudder is centered!
To engage Autopilot mode, press the STBY/AUTO key and the
Tillerpilot will lock onto the current course. The LED next to this key
will stop flashing and remain permanently lit as long as the pilot is
in Autopilot mode.
To lock the pilot onto the desired course, either steer the correct
course and then engage the autopilot, or engage the autopilot and
then adjust the heading until the correct course is being sailed (see
“Adjusting course” on page 6).
If the STBY/AUTO key is pressed and held, the pilot will beep a
second time and lock onto the previously used heading (this feature
will not be available if the unit has just been switched on).

Adjusting course
In Autopilot mode, precise course adjustments can be easily made:
- Press the port ( ) or starboard ( ) key once and a 1º course
adjustment will be made in the specified direction. This is
confirmed by a single beep and the port or starboard LED will
flash once.
- Press and hold either key and a 10º course adjustment will be
made, confirmed by a double beep and a double flash of the
port or starboard LED.
Auto Tacking and Gybing
The Tillerpilot has a built-in auto tack and auto gybe facility, allowing
easy tacking and gybing of the vessel when single- or short-handed.
The Tillerpilot will automatically select tack or gybe depending on
true wind direction:
- tacking if less than 90°
- gybing if larger than 120°
An auto tack/gybe is only possible in Autopilot mode.
To initiate autotack/gybe, press and hold the TACK key until both
LEDS illuminate and you hear a short beep. To confirm the tack/
gybe press the port ( ) or starboard ( ) keys key depending on
which direction you wish to tack/gybe. The Tillerpilot will then beep
3 times with 1 second intervals, followed by a long beep when the
tack/gybe starts.
The operation of the Tillerpilot will differ during an autotack/gybe,
depending on whether the pilot is in Steer To Compass or Steer To
Wind mode.
Autotacking/gybing in Compass mode
If in Compass mode (default), the Tillerpilot will tack/gybe the vessel
in the selected direction through an angle of 100º.
Autotacking/gybing in Wind mode
The Tillerpilot will tack/gybe the vessel through to the same true
wind angle, but on the opposite tack.
¼Note: The Tillerpilot automatically prevents tacking/gybing in the
wrong direction – if on port tack/gybe, only an autotack/gybe onto
starboard will be possible.

Autotacking/gybing in Nav mode
As the Tillerpilot will be steering directly to a waypoint, the
autotack/gybe facility is disabled while in Nav mode.
If it is necessary to perform an autotack/gybe, disengage Nav mode
by pressing the NAV key then perform the autotack/gybe.
Warning: Ensure that the boat is on the correct tack before
re-engaging Nav mode.

Advanced Features
The TP22 and TP32 Tillerpilots contain many advanced features,
including the ability to accept course data from a variety of sources
other than the internal fluxgate compass. Such sources include
SimNet- and NMEA-compatible navigational receivers (GPS/
chartplotters, etc.), wind vanes, and compass heading transducers.
Nav mode
The TP22 and TP32 Tillerpilots can interface directly with compatible
Simrad chartplotters via the SimNet high-speed data bus. They also
have an inbuilt NMEA interface, which allows connection to NMEA
0183-compatible GPS and chartplotters.
Once interfaced with a GPS or chartplotter, the Tillerpilot can steer
using data from this source in addition to the internal compass,
allowing it to steer to a waypoint with great accuracy.
To activate Nav mode, the unit must be in Auto mode (press STBY/
AUTO). Simply activate a waypoint or route programmed into the
GPS/chartplotter and press the NAV key. The LED next to the NAV
key will light and the Tillerpilot will steer to the first waypoint using
Cross Track Error and Bearing To Waypoint information from the
navigational receiver to maintain an accurate course.
On arrival at the target waypoint an intermittent alarm will sound.
As a safety feature, to avoid an unexpected course change, the next
waypoint will not be automatically loaded until the NAV key is
pressed. When the vessel reaches the final waypoint, the Tillerpilot
will continue its current course under Compass (Auto) mode.
¼Note : Some of the standard key stroke functions may have a
different effect in Nav mode than in Compass mode (see “Adjusting
course” on page 6 and “Autotacking/gybing in Nav mode”on
page 7).
Steer To Wind
The TP22 and TP32 Tillerpilots can sail to the apparent wind angle
rather than a compass course using wind data via NMEA interfaces
or SimNet. Due to the faster data rate, the use of a SimNet windvane
is recommended – priority will be given to SimNet Wind data over
NMEA Wind data received by the Tillerpilot.
¼Note: 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 starboard ( ) keys
together until a double beep is heard.
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 together again until a
second beep is heard.
While in Steer To Wind mode, the Tillerpilot will lock onto the current
apparent wind angle being sailed. Any course adjustments 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.
¼Note: Nav mode cannot be selected while in Steer To Wind mode –
to activate, return to Compass mode first.
Using an external compass
The TP22 and TP32 Tillerpilots will preferentially steer to external
compass heading whenever such information is interfaced 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
external compass would be
on the mast, between 1 and 2
meters above the deck. 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.
