Features and Benefits

{'Features_and_Benefits_1': 'Includes an A99BB-400C temperature sensor with 13 ft 1-1/5 in. (4.0 m) cable.', 'Features_and_Benefits_2': 'High-impact, thermoplastic Type 1/IP20 or Type 4X (NEMA)/IP66 watertight, corrosion-resistant enclosures increase application options, allowing surface and snap-fit DIN rail mount, or watertight surface mount.', 'Features_and_Benefits_3': 'Easy-to-read, bright, adjustable backlit LCD screen displays the temperature, parameters, and status clearly and allows you to adjust LCD brightness for the ambient light conditions. Custom icons on the display provide visual cues on system and control status.', 'Features_and_Benefits_4': 'Adjustable On and Off temperature setpoints enable easy to set up cooling or heating control applications on the three-button touchpad, eliminating the need to remove the cover and reposition jumpers for reverse or direct control actions.', 'Features_and_Benefits_5': 'Displayed temperature offset allows you to adjust the displayed temperature to the actual sensed temperature in applications where the resistance error in long sensor cable leads cause a deviation in the displayed temperature from the actual sensed temperature.', 'Features_and_Benefits_6': 'Temperature setback/offset control enables the control to shift the On and Off setpoint values by a user-defined offset when an external switch closes the binary input control circuit. Using a switching timer enables you to set up occupied/unoccupied temperature setback schedules for your applications.', 'Features_and_Benefits_7': 'Basic and advanced programming menus allow you to easily set up your control application on the LCD using a simple three-button touchpad interface'}
