The Argo Z213 Arm-3P is a 3 zone relay designed for managing hot water heating systems. It operates on a 120VAC input and is perfect for hydronic systems. This unit supports circulator management and boiler control for up to three zones, with the possibility to expand to fifteen zones using add-on modules.
This relay is suitable for both residential and light commercial settings requiring discrete zone control with priority functions and diagnostics. Preconfigured settings along with diagnostic indicators facilitate quick setup and minimize service callbacks.
We pulled together the parts most installs need for this unit, plus a few add-ons worth a look. Check what you need — nothing here blocks checkout.
