Low- and line-voltage models provide 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.
30 (F or C ) temperature differential adjustment range allows precise (1F or C ) temperature differential settings that are much tighter than electromechanical controls.
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.
Temperature Offset Function shifts the cutin and cut-out setpoints by an adjustable offset when a user-installed, external switch closes the A419 control s binary input circuit.
High-impact thermoplastic type NEMA 1 allows surface or snap-fit DIN rail mount; LEXAN 950 high-impact thermoplastic type NEMA 4X enclosures allow watertight surface mount.
Lockable front-panel touchpad allows easy setup and adjustment of the A419 control setpoint, differential, and other functions; a concealed jumper locks the touchpad to deter unauthorized adjustment of the control settings.
