AT Series C 4-Element Electric Boiler

Key Features
• An Advanced Microprocessor Control—Elements energize individually, with additional elements energizing as needed to meet demand, thus reducing electrical costs. The start-up element is rotated (similar to your car’s spark plugs) so run time is balanced across all elements for longevity.
• No Short-Cycling—The Argo “AT” Series C utilizes a sensor connected to a probe in an immersion well to determine demand. This configuration transmits water temperature back to the control board allowing the unit to ef ficiently maintain steady, even heat using only the elements needed to meet demand. This eliminates the cost and inconvenience of short cycling.
• An Advanced Load Managing Controller—Gives you the option to allow your utility or electric co-op to remotely control the boiler, reducing peak demands.
