Fan Speed Control - System Operation
System Operation
The auto amp. determines the proper value of base current according to air mix door opening angle. This is computed by air mix door control
system, which then sends this current to fan control amp. The fan control amp. amplifies its base current and makes the blower motor run. In this
way blower speed is adjusted from LO to HI. "LO" air flow volume at "FOOT" or "Bi-level" mode is different from that at "VENT" or "DEF".

Fan Speed When Starting or Stopping

seconds.
