A419 Series Electronic Temperature Controls with NEMA 1 or NEMA 4X
Watertight Enclosures
Description Features
The A419 Series controls are single-stage, • low- and line-voltage models provide
electronic temperature controls with a Single options for almost any refrigeration or
Pole, Double Throw output relay. They feature HVAC control-voltage application

Off) status. The A419 controls are available in glance
24 VAC or 120/240 VAC models. • 30° (F° or C°) temperature differential
The A419 controls have heating and cooling adjustment range allows precise (1F° or C°)
modes, adjustable setpoint and differential, an temperature differential settings that are
adjustable anti-short cycle delay, and a much tighter than electromechanical
temperature offset (setback) function. The controls
setpoint range is -30 to 212°F (-34 to 100°C). • Adjustable Anti-Short Cycle Delay
The controls feature remote sensing capability (0 to 12 Minutes in 1-Minute Increments)
and interchangeable sensors. The A419 ensures that the output relay remains off for
