Circulator Valve Controller with Zone Valve Priority.

Argo AZ-6CP 120V 6-Zone Valve Control – Multi-Zone Heating System Interface

The Argo AZ-6CP is a 120V zone valve control panel designed to manage up to six independent hydronic heating zones. This control unit provides centralized switching of 24V zone valves and associated equipment with integrated diagnostic feedback, isolated end switches, and field-selectable operating parameters. Ideal for residential or light commercial systems requiring advanced zoning control.

With a built-in transformer and Class 2-rated terminals, the AZ-6CP ensures compatibility with standard thermostats and zone actuators while providing reliable boiler and system pump interface options. It also supports integration with Argo’s optional outdoor reset module via data port connection.

Functional Overview

• Six-Zone Operation: Controls up to six 24V zone valve circuits with SPST switching relays
• Built-in Transformer: 75 VA transformer provides 24V output for valve and thermostat operation
• LED Indicators: Individual zone call LEDs for clear system diagnostics and troubleshooting
• Pump Priority Control: Dedicated terminals for primary pump operation or priority zone management
• Isolated End Switch: Electrically separates low-voltage control from boiler input circuit
• Data Port: Terminal connection for Argo DPM-2 outdoor reset and setback module
