The A419ABC-1C control is a single-stage, electronic temperature control with a Single Pole, Double Throw output relay. Featuring a lockable front-panel touchpad for setup and adjustment, and a Liquid Crystal Display for viewing the temperature and status of other functions. A Light-Emitting Diode indicates the controls’ output relay (On/Off) status. The A419ABC-1C control has heating and cooling modes, adjustable setpoint and differential, an adjustable anti-short cycle delay, and a temperature offset (setback) function. The setpoint range is -30 to 212°F (-34 to 100°C). This control features remote sensing capability and interchangeable sensors.
Features
The A419ABC-1C provides options for almost any refrigeration or HVAC control-voltage application. The easy-to-read LCD displays the sensed temperature and control-function status clearly and custom icons on the display indicate the control and system status at a glance. A 30° (F° or C°) temperature differential adjustment range allows precise (1F° or C°) temperature differential settings that are much tighter than electromechanical controls and the Adjustable Anti-Short Cycle Delay (0 to 12 Minutes in 1-Minute Increments) ensures that the output relay remains off for a user-set time delay, and helps avoid hard starts, nuisance overload outages, and unnecessary equipment wear The Temperature Offset Function shifts the cut-in and cut-in setpoints by an adjustable offset when a user-installed, external switch closes the A419ABC-1C’s binary input circuit. The high-impact thermoplastic type NEMA 1 allows surface or snap-fit DIN rail mount while the lockable front-panel touchpad allows easy set up and adjustment of the control setpoint, differential, and other functions; a concealed jumper locks the touchpad, and deters unauthorized adjustment of the control settings.
Applications
The A419ABC-1C can be used to control a wide variety of single-stage refrigeration or HVAC equipment, including freezer control in convenience stores, reach-in coolers, supermarket display cases for produce or meats, restaurant or convenience store walk-in coolers, boiler control, compressor lockout (disables the compressor when temperature exceeds limits), condensor fan cycling, pump control for cooling towers, space and return air temperature.
