Six-Zone Switching Relay, 120 VAC

Argo ARM6P Six Zone Switching Relay – Multi-Zone Control for Hydronic Heating Systems

The Argo ARM6P is a six-zone switching relay panel designed to control multiple heating zones in hydronic systems using a 120VAC power supply. It provides centralized zone control with individual priority settings, electronic circuit protection, and integrated diagnostics, making it suitable for both residential and light commercial applications.

This panel is prewired and factory-tested to streamline field installation. Designed for compatibility with standard 24V thermostats and circulators, the ARM6P reduces wiring time and simplifies service with modular relay components and clearly labeled terminals.

Core Features and Capabilities

• Zones: Controls up to six independent heating zones
• Transformer: Integrated 30 VA transformer
• Load Capacity: 10 A total relay load, supports 1/3 hp motor
• Relay Type: DPDT plug-in relays with ice cube design for ease of replacement
• Protection: Auto-reset electronic fuse safeguards relay circuitry
• Diagnostics: Relay status LEDs visible through panel window for quick assessment
• Priority Timer: Automatic override every 30 minutes to circulate heat in inactive zones and prevent stagnation

Technical Specifications

• Voltage: 120 VAC input / 24 VAC thermostat control
• Frequency: 60 Hz
• Amperage: 7.2 A max draw
• Circuit Board: Double-sided PCB, factory-tested for quality control
• Output: ZC/ZR and dry contacts for external boiler or circulator connection

Installation Considerations

The ARM6P is intended for surface-mount installation in climate-controlled mechanical rooms. Terminals are clearly marked for thermostat, transformer, circulator, and boiler connections. It is recommended that installation and commissioning be performed by licensed HVAC technicians in accordance with local electrical and mechanical codes.

Additional Functions

• Switchable Zone Priority: Allows domestic hot water or key zones to override heating cycles
• Boiler Protection Delay: 5-second shutdown delay helps reduce short cycling
• Expandability: Supports additional relay modules for more than six zones
• Isolated Switching: Dedicated ZC/ZR contacts reduce load on boiler aquastat

Professional Use Case

Engineered for professional installation, the Argo ARM6P relay panel simplifies zone control in multi-loop heating systems. With factory-assembled internal wiring, field-serviceable relays, and integrated protection features, it minimizes jobsite time and supports long-term system stability.
