As Boulter suggested, do you have the unit configured for a port side installation
when the actual installation is starboard (or the reverse)?
Do you have the response set to too high a value?
Do you have something ferrous in your pocket when you lean over the unit to push the Stby/Auto button?
Are you using an external compass
rather than the compass in the TP22 itself?
I can reset my units to their original factory state by (1) unplugging to power off, (2) pressing and holding PORT, TACK, STARBOARD, and NAV, then (3) plugging back in to power on. A few flashes and beeps follow that I can't remember right now, and all is well.
We have found the Simrad
Tillerpilots to be good gear
. We own a TP30 that we no longer use and a pair of TP32s that we have been using since the NMEA2000 models came out. We are quite happy with them after changing the original "professional" installation to match Simrad's recommendations. We have been living on our boat
for 5 or 6 months every year for the last 12 years traveling to and from the Bahamas
each year. We seldom steer by hand when traveling any distance at all.
Our only chronic problem is that they overheat in the tropical sun then suffer from heat stroke. Once cool they are OK again. Only someone from Denmark
would think black is a good idea. We throw a wet cloth over them when they are in the sun and have little white jackets tailored to fit them.
In my experience Simrad's tech service
has been quite helpful replacing a "bad out of the box" tillerpilot under warranty and replacing an out of warranty one I fell across and destroyed for a very reasonable price
. The Simrad dealer in Oriental, NC went out of his way to discover a workable method of interfacing the TP32s with my previous Simrad CP32 MkII chartplotter
My TP32s interface with my other Simrad instruments. They operate in NAV mode with my current
and produce all three autopilot
control screens on the IS40 display heads. They steer to wind
when sailing upwind.
Keep at it. You'll figure it out.
