Argo Hydronic Heating Controls & Switching Relays

Argo Industries specializes in the controls that keep hydronic heating systems running smoothly. At 24hr Supply, the Argo range includes switching relays, zone valve controls, and related accessories that coordinate multiple heating zones, circulators, and boilers into one reliable, responsive system for residential and commercial buildings.

Multi-zone comfort depends on controls that fire the right pump or valve at the right time. Argo relays handle priority domestic hot water, manage circulator staging, and protect equipment from short-cycling. Built for straightforward wiring and long-term durability, they help heating contractors deliver even, efficient comfort throughout every room of a property.

From single-zone relays to multi-zone control panels, Argo offers the building blocks of a well-designed hydronic layout. Explore our selection of Argo switching relays and complete your boiler installation with controls that installers trust.
