2 or 4 Element Configuration & Modular Boiler Configuration
Designed for maximum versatility, the Argo “AT” Series features a 2 Element boiler available
in four capacities from 6 kw to 12kw and a 4 Element boiler available in four capacities
from 12kw to 24kw. The Argo “AT” Series can also increase its’ capacity to 40kw by
“stacking” two boilers together in a Modular Boiler Configuration |

Microprocessor Based Control Board
The “AT” features an advanced Microprocessor
Control which safely and efficiently controls
the elements. Elements energize individually, with
additional elements energizing as needed depending
on demand. The start-up element
is rotated so run time is balanced across all elements
promoting longevity.
The “AT” Series utilizes a sensor connected
to a probe in an immersion well to determine
demand. This configuration relays water
temperature back to the control board allowing
the unit to efficiently maintain steady, even heat
using only the elements necessary to satisfy
demand. Thus the “AT” Boiler avoids the
constant peaks and valleys experienced by
others relying on a timer system resulting
in short-cycling of the elements that wastes energy
and costs the user more in electricity. |

Installation, Operation and Maintenance
The Argo “AT” Series features - Diagnostic Indicator Lights, a 30 Second Pre-Purge, an Adjustable Temperature Set Point and Differential and a factory installed Circulator Relay plus on board power for an External System Circulator. Optional components such as Low Water Cut Off, Flow Switch, etc. are easily added via connections on the control board. The “AT” is available in one compact cabinet size for ease of installation. Safety features include Operating Limits with Back-Up, Redundant Relays Per Element and Audible Alarms/Fault Codes. |
