New ECat Update Version 6.0.366/5.0.366 Now Available

| May 2026

What's Changing:

  1. The 6% surcharge has been absorbed into standard ECat pricing for RNA, RQA, RZA, H3, V3, CFA, SA, SB, and M2.
    • You will no longer need to input a surcharge percentage in the pricing tab of Edit Order dialog box.
    • Rerun any units and verify that the surcharge percentage is 0% beneath the subtotal on the worksheet report.

  2. For RQA, RNA, and RZA a new price has been added to the SERIES feature to reflect the base cost of a unit.
    • This price has been offset in features A2 and A3 to create a neutral price adjustment.
    • Non-compressorized DX air handlers (A2-P) and Chilled Water units (A3-EF) will need to be re-ran to reflect pricing changes due to market dynamics.

  3. Digital Compressor Pricing in some RNA-B and C cabinets have been adjusted to include the price of the standard lag 2-step compressor in feature A1.
    • This will allow users to better identify the cost of each lead compressor technology option.
    • Feature A5-A for two circuit units will now be $0 and Feature A5-B dual digital compressor option has been adjusted. This is a price neutral pricing change.

  4. RQA Feature 11A-EQ for Modulating Hot Gas Reheat has been updated to reflect market dynamics.
    • Please re-run any RQA units with Modulating Hot Gas Reheat.

  5. Updates and bug fixes to controls related features and items.
    • This may affect the price of your unit.
