DFT-880 Defrost Module

(1 customer review)

RRP $324.00 Inc. GST

The DFT-880 defrost module is a perfect replacement part for older mechanical defrost controllers


SKU: DFT-880 Category: Tags: ,

The DFT-880 uses a powerful microprocessor to accurately monitor and control all functions of the de-ice process. Further the DFT-880 indicates the current status via 2 clearly marked LEDS. This advanced control logic helps ensure the de-ice process is accurately controlled to ensure best HVAC equipment performance. To offer the most value for your investment the DFT-880 operational parameters can be easily fine tuned to suite the demands of the particular reverse cycle unit the DFT-880 is servicing. Simply by changing some DIP switch settings the de-ice initiation temperature, the de-ice termination temperature as well as the de-ice inhibit time.

    I ordered a DFT-880 after phoning Smart Temp to check that I could use it to replace a 20 year old Temperzone Electronic De-Ice Controller that had failed. The help on the phone was really appreciated, but the next day delivery was truely AMAZING. The DFT-880 and the new temp probe that came with it was an easy install and the module worked exactly as it should. I’m happy to confirm that it does what Smart Temp said it would do and I’m very happy to recommend Smart Temp as a company that produce a quality product and then support it with excellent service.
