The furnace controls the fan because oil and gas heat is not instantaneous. When the minimum fan speed is reached, the ALERT pin changes from a digital HIGH to LOW. A Customer Service representative can help you determine compatible fans. The receptacle is part of the house wiring and the fan assembly plugs into this receptacle. How I plan on wiring the fan it will only use high speed if the AC is on. You can see that in this way, with a SPDT switch, we can control 2 different circuits or devices. Standard AC with Variable Speed Air Handler and Two Stage Heat Control Wiring 7 This diagram is to be used as reference for the low voltage control wiring of your heating and AC system. Control of the speed of a fan for PC 2-wire by the use of a pwm Arduino, going to use a transistor due to a voltage of 12 volts able to operate from a common PC fan, thanks to the vision. I want to read the rpm and control the speed of a 12V - four wire fan through Arduino. The Gray wire from the A/C relay goes to the +12 volt of the A/C compressor clutch wire. Speed control of a DC motor is either done manually by the operator or by means of an automatic control device. Wiring a variable speed motor is the same as wiring a single speed motor, as the speed control function is an integral part of the motor. Put knob on stem. RPM is for Revolutions Per Minute. Now you can change the fan speed and adjust light level with one control - eliminating inconvenient pull chains.
