How To Wire An Electric Fan With An Ac Trinary Switch Update Youtube Note: this video has been edited and re uploaded due to what was a mislabeled component in the video. thanks to all that made us aware of the error in the co. A trinary switch will allow your electric fan to turn on and off based on either engine temperature or ac system demand. keep your engine and yourself cool b.
How To Wire A Trinary A C Switch The ac trinary switch is an important component in an automotive air conditioning system. it serves as a sensor that monitors the pressure and temperature of the air conditioning system and helps to control the operation of the compressor. the trinary switch has three functions: it detects the system pressure, the temperature of the refrigerant. The benefits of using the trinary switch to control the fan rather than having the fan come on only when the a c clutch is engaged is as follows: 1. if the natural air flow from driving down the road is sufficient to cool the condenser, the radiator fan will not run (unless engine temp dictates it), which saves wear and tear on the radiator fan. Dual electric fan activation with ac trinary switch separate fans. if you have multiple engine fans, and would like to have the option of turning them on separately with a temp sender switch for fan 1 and a manual override switch for fan 2, use this setup. fan 1 is activated by the temp switch or the a c trinary switch. Step 5: test the ac system. once the wiring is complete, it is important to test the ac system to ensure that the trinary switch is functioning correctly. reconnect the negative battery cable and start the engine. turn on the ac system and check for proper operation of the compressor and condenser fans.
Trinary Switch Wiring With Dual Fans Dual electric fan activation with ac trinary switch separate fans. if you have multiple engine fans, and would like to have the option of turning them on separately with a temp sender switch for fan 1 and a manual override switch for fan 2, use this setup. fan 1 is activated by the temp switch or the a c trinary switch. Step 5: test the ac system. once the wiring is complete, it is important to test the ac system to ensure that the trinary switch is functioning correctly. reconnect the negative battery cable and start the engine. turn on the ac system and check for proper operation of the compressor and condenser fans. The trinary switch is designed to close circuit to fan, when pressure gets to a certain level. that way fan comes on, and cools the condenser, bringing the operating pressure down. if the pressure in system gets too high, or too low, then the binary part of that trinary switch, will cut out the compressor, for safety reasons. Rex explains how to wire a trinary switch for your vintage air system. this switch turns on an electric radiator fan to help regulate the pressure in your ai.
