    Honeywell Fan And Limit Controllers Are Used For Control Of High Limit And Fan Motors In All Types Of Forced Air Heating Systems.

    Controllers have two switches, one which opens the limit circuit if the plenum temperature exceeds the preset safety limit and then resets automatically. The other switch turns the fan on and off. Controllers may be used as limit controllers by wiring only the limit side. Limit contacts are suitable for line voltage or low voltage. Controls adapt to many competitive mounting holes in replacement applications.

    Electronic Fan Speed Controls Provide An Alternative To Fan Cycling Control For Small And Medium Size Refrigeration And Heating, Ventilating, And Air Conditioning (HVAC) Applications.

    Electronic Fan Speed Controls are refrigerant pressure actuated, electronic motor-speed controllers. Use with manufacturer approved single-phase permanent split-capacitor motors. Controls sense condenser refrigerant pressure and automatically adjust fan motor speed according to sensed pressure to provide condenser pressure control. The soft start capability provides a smooth fan startup, which reduces motor-starting noise and abrupt changes in motor speed and the motor control provides a wide range of condenser fan motor applications. Enclosures allow indoor and panel mounting or outdoor mounting. Built-in voltage surge protection. Available in a variety of operating ranges.

    Warm Air Limit Controls With Manual Reset Are Used For High Temperature Cut-Out Applications.

    Warm Air Limit Controls lock out on a temperature increase to the control set point. Manual reset is required before the electrical contacts can be reclosed, so the trip-free reset lever does not permit restarting until the reset lever is manually released. The A25 is normally located in a return air duct and is wired to shut down air conditioning or ventilating fans when the temperature of the air becomes excessively hot. Rod and tube type sensing element provides positive control action. Range adjusters operate with either a knob or a screwdriver slot, and are available with SPST or SPDT switch action.
