Argo 6 Zone Relay with Priority ARM6P Boiler

Description

Product Overview

The Argo ARM6P 6‑zone relay is engineered for robust multi‑zone heating applications. Built by Argo Technology, this unit measures 12 x 8 x 4 inches and fits standard 24 Vac transformer terminals. It supports up to 15 zones, offering separate isolated switches (XX) and ZC/ZR relays that protect the boiler aquastat. A built‑in diagnostic light provides real‑time status, while a 5‑second time delay ensures safe boiler shut‑off. Designed for 2 Amp, 1/3 HP operation, the plug‑in, add‑on zone modules (AD1 or AD4) allow flexible expansion.

Usage

Ideal for residential homes, small apartment buildings, and light‑commercial properties, the ARM6P controls multiple heating circuits with precision. Install it in a mechanical room or near the boiler to manage circulator priority, ensuring rapid heat delivery to high‑demand zones. The relay’s isolated switches prevent cross‑talk between zones, making it suitable for complex HVAC layouts where reliability is critical.

FAQ

Can the ARM6P be used with any boiler?

Yes, it is compatible with most standard boilers that operate on a 24 Vac control circuit, provided the boiler’s aquastat rating matches the relay’s specifications.

What is the purpose of the diagnostic light?

The diagnostic light indicates relay status and alerts you to any zone faults, simplifying maintenance and reducing service time.

How does the circulator priority function work?

When multiple zones call for heat, the priority circuit activates the circulator for the most critical zone first, ensuring rapid heat delivery where it’s needed most.

Is installation DIY‑friendly?

While the ARM6P is designed for straightforward wiring, we recommend a qualified HVAC technician for initial setup to ensure optimal performance and safety.

Can additional zones be added later?

Yes, the plug‑in AD1 or AD4 zone modules allow you to expand the system without replacing the main relay unit.
