2.5 Using WindTrim mode

Note: You can only use WindTrim mode if the tiller pilot is connected to a suitable wind sensor/instrument providing wind direction data.

To use WindTrim mode, the tiller pilot must receive wind information from one of the following sources:

•SeaTalk wind instrument

•NMEA wind instrument

•Raymarine pushpit wind vane (part number Z159) connected via supplied SeaTalk interface

In WindTrim mode the tiller pilot maintains a course relative to an apparent wind angle. The pilot uses WindTrim to eliminate the effects of turbulence and short term wind variations. This provides smooth precise performance with minimum power consumption.

WindTrim mode uses the fluxgate compass as the primary heading reference. When changes in the apparent wind angle occur, the tiller pilot adjusts the locked compass heading to maintain the original apparent wind angle.

In WindTrim mode, the tiller pilot ignores short-term changes in wind direction, yet still tracks real wind shifts as subtle as 1°.

Selecting WindTrim mode

From Standby mode or Auto mode, press standby and auto together to select WindTrim. The tiller pilot will then maintain the current apparent wind angle.

Note: The tiller pilot beeps once every 30 seconds in WindTrim mode.
