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.
