18 ST7002 SmartPilot Controller Operating Guide2.2 Using Wind Vane mode – sail boatsNote:You can only select Wind Vane mode if the SmartPilot is receiving suitable SeaTalkor NMEA wind direction information.What is Wind Vane mode?When the SmartPilot is in Wind Vane mode it uses the fluxgate compass as theprimary heading reference. As changes in the true or apparent wind angle occur,it adjusts the locked heading to maintain the original wind angle.Wind informationTo use Wind Vane mode, the SmartPilot must receive wind information from oneof the following sources:• SeaTalk wind instrument connected to the autopilot via SeaTalk• NMEA wind instrument• Raymarine pushpit wind vane connected via a SeaTalk interfaceTrue and apparent windSmartPilots can maintain a course relative to either an apparent or true windangle in Wind Vane modeThe default setting is apparent wind. If required, you can change this to true windin User Calibration (seepage 24).WindTrimIn Wind Vane mode the SmartPilot uses WindTrim to eliminate the effects ofturbulence and short term wind variations. This provides smooth and preciseperformance with minimal power consumption. You can adjust the windresponse (WindTrim) level in User Calibration (seepage 24) to control how quicklythe SmartPilot responds to changes in the wind direction. Higher wind trimsettings will result in a pilot that is more responsive to wind changes.How do I select Wind Vane mode?You can select Wind Vane mode from either Standby or Auto mode:1. Steady the boat onto the required wind angle.2. Press standby and auto together to select Wind Vane mode and lock thecurrent wind angle:• the display shows the locked heading (e.g. 128°) and the wind angle(e.g. WIND 145P indicates an wind angle of 145° to port)• if the SmartPilot does not enter Wind Vane mode, it is not receiving winddata - check the instrument and connections
