Intermatic DTAV40 Defrost Timer

The Intermatic DTAV40 Defrost Timer is a heavy-duty, 40-amp electromechanical control engineered for reliable commercial refrigeration defrost cycles. Designed as a versatile universal defrost timer, it features auto-voltage technology that automatically adjusts between 120V and 240V AC, eliminating the need for manual jumpers or voltage-specific stock. This unit serves as an exact refrigeration timer replacement for discontinued models, including the Paragon 8047-00 and Precision 6041-0, ensuring a seamless retrofit without bracket modifications if using the recommended non-metallic base. Equipped with captive trippers, the Intermatic DTAV40 allows for precise defrost schedule programming in 15-minute increments. The NEMA 3R outdoor enclosure and conformal-coated circuit board provide superior protection against moisture and high-humidity environments typical of walk-in coolers and freezers. With a robust 40A resistive rating and 2HP motor capacity, this 24-hour timer supports time-initiated defrosting with termination options via time, temperature, or pressure switches. Integrated LED indicators provide immediate visual confirmation of the refrigeration and defrost cycles during diagnostic checks.

• Universal Compatibility: Replaces over 40 competitive models, including Paragon 8040, 8140, and 8240 series, reducing the need for multiple truck stock items.
• Rugged Reliability: Features a moisture-resistant conformal-coated board and a heavy-duty 40A relay designed for high-cycle industrial use.
• Simplified Installation: The auto-voltage input sensing detects 120V or 240V automatically, preventing wiring errors on-site.
• Tactile Programming: Captive trippers cannot be lost and allow for 48 daily operations with a minimum 15-minute duration.
• Environmental Protection: Enclosed in a standard NEMA 3R plastic case suitable for both indoor and outdoor refrigeration applications.

How do I wire the DTAV40 to replace a Paragon 8145?
The DTAV40 terminal identification is identical to the 8145, with the additional "F" terminal. Use the provided terminal block labels to match original wiring for a direct swap.

Can this timer handle both electric heat and hot gas defrost?
Yes. The 1 SPDT and 1 NC SPST switch configuration is suitable for compressor shutdown, electric heat, and hot gas defrost systems.

What wire size is required for maximum load?
For full 40-amp loads, you must use #8 AWG copper wire rated for a minimum of 90?C to comply with electrical codes.
