6 This setup turns the fan on as soon as the A/C switch is turned on. RELAY power ahead of the A/C thermo switchdoes not cycle the fan on and off as the compressor cycles due to the thermo switch setting. The optional ground switch from RELAY 1 willdisable this function if set to ground. The fan would then operate only when activated by the fan temp switch, the trinary switch, or theoptional manual override switch from RELAY : Typical ground trigger trinary switch connection AN ELECTRIC FAN WHEN A/C IS TURNED ONto 12V ignitionElectricfan3087868586873085AC thermo switchElectricFan RELAY "A/C on"additional fanactivation RELAY Trinary SwitchHigh pressure compressor cutoffLow pressure compressor cutoffPreset pressure for fan RELAY groundpage 3from A/Charness"on"switchManual"A/Cr on - fan on"override switchManual "fan on"override switch12V ignitionpinkredorangeblackblackredorange pinkBlack/greenorred/whiteBlue/whiteBlac k/greenorblack/whiteFan temp switchsending

10 Momentarily grounding the S terminal switches the RELAY permanently to either 56a or 56b . The path is altered every time the S terminal is grounded. Because it is a mechanical device, the selected path is maintained until the S terminal sets another ground.
