Details
The A419 series controls are single-stage, electronic temperature controls with a Single-Pole, Double-Throw (SPDT) output relay. They feature a lockable front-panel touchpad for setup and adjustment, and a Liquid Crystal Display (LCD) for viewing the temperature and status of other functions. A Light-Emitting Diode (LED) indicates the controls? output relay On/Off status. The A419 controls are available in 24 VAC or 120/240 VAC powered models. The A419 controls have heating and cooling modes, adjustable setpoint and differential, an adjustable anti-short cycle delay, and a temperature offset 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, high-impact plastic enclosure suitable for surface or DIN rail mounting or NEMA 4X watertight, corrosion-resistant surface-mount enclosures.
Features:
- Wide Setpoint range: -30 to 212° F (-34 to 100° C)
- Adjustable differential from 1 to 30° F (1 to 30° C)
- Adjustable anti-short cycle delay from 0 to 12 Minutes.
- Switch-Activated temperature offset function that allows the users to shift the setpoint based on an external switch such as a time clock.
- User selectable sensor failure mode. Allows the user to determine how the controller will operate when the sensor or sensor wire fails.
- Operates in either heating or cooling mode.
- Remote sensor. The sensor can be located up to 500 feet from the control so long as a large enough wire gate is used.
- Easily replaceable sensor. No cutting of wires or soldering is required.
