A419 gbf-1C series: electronic temperature control
THIS ITEM IS NEW HAS PROBE AND PAPERS
The Temperature Offset Function 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 set point and differential, an adjustable anti-short cycle delay, and a temperature offset (setback) function. The set point range is -30 to 212 F (-34 to 100 C). The controls feature remote sensing capability and interchangeable sensors..
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.
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.
shifts the cut-in and cut-in set points 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.
Lockable front-panel touchpad allows easy set up and adjustment of the A419 control set point, differential, and other functions; a concealed jumper locks the touchpad, and deters unauthorized adjustment of the control settings.
Low and line-voltage models provide options for almost any refrigeration or HVAC control-voltage application.
