Honeywell 30112A Potentiometer 135-Ohm

The Honeywell 30112A is a 135 Ohm, potentiometer, this is a variable resistor that is used to control the amount of current passing through it. It functions by sliding one end of a resistor across a resistive path and varying the connection between the wiper and the terminals. This allows a precise control of voltage or current in various applications as needed. In HVAC systems it is used in control circuits for modulation of the gas valves, fan speeds and position of the dampers. Some benefits of the 30112A include; smooth operation, stability, and durability.
