Code No. LIT-1927385 Issued July 1, 2006 A419 Series Electronic Temperature Controls with NEMA 1 or NEMA 4x Watertight Enclosures
Description
The A419 series controls are single-stage, electronic temperature controls with a Single Pole, Double Throw output relay. They feature 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 A419 controls are available in 24 VAC or 120/240 VAC models. The A419 controls have 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). The controls feature remote sensing capability and interchangeable sensors. The A419 controls are available in either NEMA 1, highimpact plastic enclosure suitable for surface or DIN rail mounting or NEMA 4X Watertight surface-mount enclosures. · the 30° (F° or C°) temperature differential adjustment range allows precise (1F° or C°) temperature differential settings that are much tighter than electromechanical controls 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 A419 control's binary input circuit the high-impact thermoplastic type NEMA 1 allows surface or snap-fit DIN rail mount; the Noryl® high-impact thermoplastic type NEMA 4X enclosures allow watertight surface mount lockable front-panel touchpad allows easy set up and adjustment of the A419 control setpoint, differential, and other functions; a · concealed jumper locks the touchpad, and deters unauthorized adjustment of the · control settings · · · · · · A419 Control and Sensor Features
· low- and line-voltage models provides options for almost any refrigeration or HVAC control-voltage application 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 Applications
The A419 can be used to control a wide variety of single-stage refrigeration or HVAC equipment. Typical applications include: · · 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 Selection Chart
