AIR CONDITIONING SYSTEM


  1. CONSTRUCTION


    1. On models with automatic air conditioning system, a pulse pattern type servomoter is used.

    2. In contrast to the previous type that detects the position by way of a potentiometer voltage, the pulse pattern type servomotor detects the relative position by way of 2-bit on/off signals.

    3. The forward and reverse revolutions of this motor are detected by way of 2 phases, A and B, which output 4 types of patterns. The air conditioning amplifier assembly counts the number of pulse patterns in order to determine the stopped position.
