sel in the selected direction The Tillerpilot has a factory preset
autotack angle of 100
242 Autotacking in Wind mode
The Tillerpilot will tack the vessel through to the same appar
ent wind angle but on the opposite tack
NOTE As a safety feature the Tillerpilot will only allow an autotack if
the apparent wind is less than 90 ie autotack is disabled
when sailing In this mode the Tillerpilot automatically prevents tacking in
the wrong direction if on Port tack only an autotack onto
Starboard tack will be E04586

TP22TP32 ADVANCED FEATURES
The TP22 and TP32 Tillerpilots contain many advanced fea
tures one of which is the ability to accept course data from a
variety of sources apart from the internal fluxgate compass
including SimNet and navigational
receivers etc and windvanes An external
SimNet compass can also be used
31 Nav mode
The Tillerpilot can interface directly with compatible Simrad
Chartplotters via the SimNet highspeed data bus It also has
an inbuilt NMEA interface which allows connection to
GPS and 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
STBYAUTO Simply activate a waypoint or route pro
grammed into the and press the NAV key

32 Steer To Wind
The Tillerpilot can sail to the apparent wind angle rather than
a compass course using wind data via the SimNet or NMEA
interfaces Due to the faster data rate the use of a SimNet
windvane such as the Simrad IS12 Wind is recommended
priority will be given to SimNet wind data over NMEA wind

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 Auto mode
Initiating an autotack will turn the boat onto the same appar
ent wind angle on the opposite tack As a safety feature auto
tack is disabled when sailing Nav mode cannot be selected while in Steer To Wind mode

TP22TP32 Using an external compass
Normally the accurate operation of a autopilot
is very difficult on a ferrous hulled boat steel ferro cement
etc as the hull will affect the bearing read by the internal flux
gate compass
Although the Tillerpilot operates using its inbuilt fluxgate com
pass it will give priority to an external SimNet Compass if
detected on the network bus
On a steel or ferro hulled boat the correct location for the
external compass would be on the mast between 1 and 2
metres above the deck Fig 33 On a nonferrous hulled boat
the compass should be situated low down as near the centre
point of the boat as possible but away from any sources of
magnetic interference such as speakers etc

43 Adjusting Gain
The Tillerpilot will apply adjustments to the tiller in order to
compensate for heading variations the amount of movement
being proportional to the heading error detected by the com
pass unit The amount of movement is set by the Gain some
times referred to as the rudder ratio
The Gain setting can be likened to driving a motor vehicle at
high speeds very little wheel movement is necessary to steer
the vehicle LOW gain When driving at slow speeds more
wheel movement is necessary HIGH gain
Fig 44 shows the effect of setting the Gain too low A the
vessel takes a long time to return to the correct heading
B shows the ideal setting where errors are quickly corrected
C illustrates the effects of setting the Gain too high which
causes the vessel to oscillate around the correct heading
A B C D Excessive Gain D creates a tendency to instability of course
leading to increasing error

In heavy seas more variations in heading will be detected and
if the Tillerpilot tried to respond to all of these errors it would
be overworked causing unnecessary strain to the unit and
excessive drain on the batteries Instead it continuously moni
tors the corrections applied over the course of a voyage and
allows a dead band within which the boat can go off course
without constant corrections being made Fig 46 The size of
the dead band is normally automatically adjusted by the Tiller
pilot to give the best compromise between course holding and
battery consumption but it can be set manually if desired
In Calibration mode press TACK to toggle between Gain
and Seastate adjustment indicated by the Port LED illumi
nated The Seastate level is indicated by the number of
audible beeps and flashes of the Nav LED No beeps or

TP22TP32 45 Autotrim
Under differing conditions a tiller bias sometimes known as
standing helm or rudder trim is applied in order to steer a
straight course An example is when sailing close hauled where
the vessel will normally pull into the wind and the helmsman
Ideal course
Wind applies a standing helm to leeward in order to maintain course
Tide The amount of this standing helm varies according to factors
ou ut
such as strength of wind boat speed sail trim and amount of
rs otr
sail set If no account of these were taken then the vessel would
wi im
tend to veer off course or pull around headtowind when sail
ing close hauled
The Tillerpilot continuously monitors the average course error
and applies a bias to the tiller to compensate until the optimum
condition is reached Fig 47 This bias or standing helm is
applied gradually so as not to upset the normal performance
of the Tillerpilot Thus it may take up to a minute or so to fully
compensate after changing tack Once optimum trim is reached
Fig 47 Effects of autotrim the pilot will still monitor for changes in the prevailing condi
tions and update the trim NOTE Autotrim is applied automatically and cannot be manually

5 Fitting the Tillerpilot
The Tillerpilot is a very sophisticated piece of equipment and
therefore in order for it to function to its full capabilities it is
essential that it is installed correctly Please read this section
thoroughly before attempting installation and use
The Tillerpilot should be horizontally level when fitted to the
tiller Fig 51

Fig 52 Installation plan view
NOTE The pilot is factory preset to be mounted on the Starboard side
as shown but this can be reconfigured for Portside mounting
see section 41
The dimensions given in Figures 51 and 52 should be adhered
to as closely as possible especially Fig 51 Some tolerance on
the distance from tiller stock Fig 52 is permissible but the
Tillerpilot may require a Gain adjustment to 19
TP22TP32 If the dimensions given are not practical for the vessel to which
the Tillerpilot is to be fitted a range of fitting accessories are
available to facilitate correct installation Please refer to section
64 for more The Tillerpilot houses an internal fluxgate compass and should
therefore be mounted away from sources of magnetic interfer
ence such as the vessels steering compass The minimum safe
distance is 1m 3ft 3in
The Tillerpilot is mounted using a supplied tiller pin and
mounting cup which allows the unit to be fitted and stowed
easily
To fit the tillerpin drill a 63mm 025in hole in the tiller
ensure that this is on the centreline of the tiller and is vertical

52 Electrical installation
The Tillerpilot operates from a 12v DC supply The waterproof
plug fitted to the Tillerpilot is used to supply the power SimNet
and NMEA data
The bulkhead socket should be mounted in a convenient posi
tion close to where the Tillerpilot is to be fitted and wired as

IMPORTANT If the vessel has more than one separate battery bank when
connecting the Tillerpilot to the power supply always ensure
that the pilot and all interfaced equipment whether SimNet
or NMEA are connected to the same battery bank even if
they each have independent connections to the switch panel
This is to avoid a possible voltage drop between the interfaced
equipment which would render the equipment Mount the bulkhead socket on a vertical surface to prevent

equipment to its own breaker in the switch panel
Ensure all wire ends are tinned and any connections are well made Poor
contact will result in loss of thrust from the Tillerpilot and slower speed

TP22TP32 Interfacing via SimNet
The Tillerpilot is linked to other equipment
via the integral SimNet cable and plug in the bulkhead socket
All SimNet units Instruments Radars Auto
pilots etc use the same single cable highspeed network bus to
share data
The system is no setup is required simply plug
the Tillerpilot into the nearest spare SimNet port and it will
automatically detect any data on the network that it can use If
there are no spare SimNet ports convenient a threeway cable
joiner can be used to create an additional port Fig 57

NOTE Some third party equipment does not have a dedicated
COMMON connection In this case the DATA connection will
usually be labelled NMEA OUT and the NMEA Common wire
from the Tillerpilot should be connected directly to 0v termi
nal 2 If in any doubt refer to the manufacturer or Simrads
Product Support department for Due to the limitations of NMEA0183 it is recommended that
only one talker is transmitting to the Tillerpilot at any one time
ie instruments or not both If more than one unit needs to be interfaced to the Tillerpilot
these should be connected to the NMEA cable via a changeover
switch
Because of the vast number of different manufacturers and
models of navigational equipment Simrad cannot guarantee
correct operation and installation of this equipment Therefore
before connecting any equipment to the Tillerpilot it is impor
tant that the units manual is referred to with regard to inter
facing via NMEA
55 Electronic interference suppression
The Tillerpilot has been designed to minimise the effects of
interference generated by the engine alternator However pre
cautions should still be taken by routing the cables away from
the engine compartment Do not run the cables down trunking
carrying high current or radio antenna cables
Engines with spark ignition also some refrigerators should be
fitted with suppressors Your local agent should be able to
advise on this and supply suppression kits where 23
TP22TP32 Auto compass calibration
Once the Tillerpilot is installed it is necessary to calibrate the
internal compass to compensate for deviation caused by any
metallic or magnetic objects surrounding it on the vessel
With the vessel motoring slowly 23 knots in calm conditions
and the Tillerpilot in Standby mode press the Starboard
key a number of times to induce a slow clockwise rotation of
the vessel Then press and hold the TACK key followed by the
Port and Starboard keys Fig 59

Fig 59 Auto compass calibration
The Port and Starboard LEDs will both light Allow the vessel
to turn through a minimum of 11 4 turns 450 in approximate
ly 2 minutes during which time the fluxgate compass will
automatically calibrate itself
If the rate of turn or boat speed is too fast the Port LED will
flash Fig 510 Either slow the boat or reduce the angle of turn
TACK
Fig 510 Rate of turn too fast
If the rate of turn or boat speed is too slow the Starboard LED
will flash either increase the boat speed or increase the angle
of turn A short beep will indicate that the calibration has been
successful and the Tillerpilot will return to Standby mode If
the calibration has been unsuccessful after a period of four min
utes a long beep will sound
NOTE If the calibration routine keeps failing after repeated attempts
this indicates that the Tillerpilot is experiencing excessive mag
netic deviation that it cannot compensate for Check the area
within 1m 3ft of the Tillerpilot for likely sources such as cock
pit speakers or large metallic objects if these cannot be relo
cated it may be necessary to fit an external compass

57 Configuring the Tillerpilot on the SimNet bus
Normally the Tillerpilot can be connected to the SimNet bus
and it will automatically detect the nav and instrument data
sources with no user intervention necessary
If the SimNet bus includes more than one data source the
Tillerpilot will use the first source it detects Fig 511

NMEA GPS AP25 IS12 Mega
CP44 RFC35R Compass
Fig 511 Example of multiple data sources
In the example above there are two nav data sources the CP44
Chartplotter and the NMEA GPS via the IS12 Mega instrument
and two external heading sources the IS12 Compass and the
RFC35R Rate Compass via the AP25 Autopilot The Tillerpilot
could be used as a backup pilot while still using the RFC35R
as the heading data source However the Tillerpilot may auto
matically select the IS12 Compass as the heading data source
and it may select the Mega instrument as the nav data source
instead of the CP44
If these are not the desired sources they can be manually con

61 Advice on operation
When used correctly your Tillerpilot can maintain as good a
course on most points of sail as a skilled helmsman with the
advantage that it never gets distracted whereas a human can
start showing lapses of concentration after as little as 10 mins
However there are certain circumstances where a human has
the advantage in being able to anticipate events which no
autopilot can sense typically in a heavy following sea The
following advice should improve efficiency when sailing using
your 1 When sailing close to the wind it is easy to forget to trim
the mainsail allowing excessive weather helm to build up
Where a human helmsman would quickly complain the auto
pilot will struggle on and the boat will be sailed less efficiently
Whereas a human normally likes to feel some weather helm
this is not necessary for the functioning of the Tillerpilot
Power consumption wear and drag will be greatly reduced if
the mainsail is freed or reefed a little sooner than normal when
sailing manually
2 It is also advisable when sailing close hauled to set a
course a few degrees free of that normally sailed under manual
control to avoid luffing into the wind
3 When running dead downwind a human pilot can see
visual signs warning him if the boat is about to gybe which
the Tillerpilot cannot sense it is advisable not to sail as close
to the gybe as you may do when sailing manually
4 When broad reaching or running fast particularly with
quartering waves a helmsman will naturally apply periodic
larger angles of helm than when beating or sailing slowly This
is the equivalent of increasing rudder Gain and it may be a
good idea to adjust the Gain on the Tillerpilot Many people
prefer to find a compromise setting which is used for all sail
ing but with practice it can be optimised for different condi
tions eg low for motoring in a calm sea or high for running
fast If the Gain is set too low the boat will go off course
because insufficient rudder is applied in time if the Gain is too
high the boat will overcorrect increasing power 5 The Tillerpilot is a highly advanced piece of equipment
However it would be a mistake to become complacent As
with all electronic navigational equipment it is an aid to navi
