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. Key Benefits for Contractors 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. Common Questions & Technical Insights 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.
