Chapter 2: Using the Tiller Pilot 232.5 Using WindTrim modeNote: You can only use WindTrim mode if the tiller pilot is connectedto a suitable wind sensor/instrument providing wind direction data.To use WindTrim mode, the tiller pilot must receive wind informationfrom one of the following sources:• SeaTalk wind instrument• NMEA wind instrument• Raymarine pushpit wind vane (part number Z159) connected viasupplied SeaTalk interfaceIn WindTrim mode the tiller pilot maintains a course relative to anapparent wind angle. The pilot uses WindTrim to eliminate the effectsof turbulence and short term wind variations. This provides smoothprecise performance with minimum power consumption.WindTrim mode uses the fluxgate compass as the primary headingreference. When changes in the apparent wind angle occur, the tillerpilot adjusts the locked compass heading to maintain the originalapparent wind angle.In WindTrim mode, the tiller pilot ignores short-term changes in winddirection, yet still tracks real wind shifts as subtle as 1°.Selecting WindTrim modeFrom Standby mode or Auto mode, press standby and autotogether to select WindTrim. The tiller pilot will then maintain thecurrent apparent wind angle.Note: The tiller pilot beeps once every 30 seconds in WindTrim mode.2 Using the Tiller PilotD5558-1
