Johnson Controls Single Stage Digital Temperature Control
Johnson Controls Single Stage Digital Temperature Control (120/240v SPDT)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.$73.90 -

Johnson Controls Hot Water Cutout Temperature Control
Johnson Controls Hot Water Cutout Temperature Control w/ Manual Reset (100-240F)Johnson Controls A19 Series temperature controls are designed to cover a broad range of uses for heating and general purpose requirements. Controls have SPST contacts which open on temperature increase or they may be supplied in single-pole, double-throw contact action. Various control ranges are available to cover working temperatures from -30 to 550° F (-34 to 288° C). Closed tank fittings and bulb wells are available for immersion applications. These controls are designed for open low and open high applications. Where critical or high value products are to be maintained within a specific temperature differential, a single control should not be applied to function as both an open low and open high control. In these applications, a separate backup control with alarm contacts should be wired to indicate when the back-up control operates.$78.07 -
