Resideo ARD5TZ Damper

Secure precise airflow control with the Resideo ARD5TZ, an industry-standard 5-inch automatic round damper designed for seamless integration into modern 24Vac zoning systems. This two-position damper is engineered for high-performance residential and light commercial HVAC applications, serving as the direct professional replacement for the legacy CRDS05 model. Built with heavy-duty galvanized steel and a single-blade configuration, the ARD5TZ features a power-closed spring-return open (PC/SRO) actuator, ensuring a fail-safe open position during power loss to maintain critical airflow.

The M847D actuator provides 30-second power cycles and a rapid 10-second spring return, significantly reducing noise during operation. For specialized installs, the reversible actuator can be field-converted to power-open/spring-closed, making it a versatile HVAC zone damper for fresh air intake or combustion air applications. The blade edge is reinforced with a high-density gasket, rated for systems operating up to 1-inch wc to minimize bypass leakage. Contractors will appreciate the two-wire installation featuring push-in terminals, simplified adjustable range stops for balancing, and a clear mechanical position indicator for rapid diagnostic checks on-site.

• Precise Airflow Management: The 5-inch diameter and single-blade design optimize forced air zoning for better temperature consistency.
• Durable Construction: Heavy-gauge galvanized steel casing and reinforced blade assemblies prevent deforming in high-velocity ducts.
• Installation Efficiency: Tool-less push-in terminals and a 2-wire configuration streamline wiring to the TrueZONE or similar 24V panels.
• Fail-Safe Reliability: The spring return open mechanism ensures the zone remains accessible if the actuator loses signal or power.
• Field Versatility: Direct compatibility with rigid or flexible round ductwork via crimped (male) and uncrimped (female) ends.

Is the ARD5TZ compatible with older Honeywell zoning panels?
Yes, as a 24V two-position damper, it integrates with most 24Vac zoning controllers, including the TrueZONE (HZ311, HZ322, HZ432) and older models originally paired with the CRDS05.

How do I change the ARD5TZ to a power-open configuration?
The M847D actuator is reversible. By removing the actuator from the shaft, rotating it, and re-securing it to the damper, you can convert it from power-closed to power-open for fresh air intake applications.

What is the purpose of the M4 terminal on the motor?
The M4 terminal provides an optional signal for LED indication to confirm the damper is in the open position, though only two wires (M1 and M6) are required for basic HVAC damper motor operation.
