Smart Equipment (SE) Control v4.4.0.31 Firmware Update Release

Date Issue: 10/5/23

Ducted Systems is pleased to announce the release of v4.4.0.31 firmware update for Smart Equipment (SE) control boards. This update features new firmware upgrade improvements, several fixes, and modifications to current control applications. For full details on changes included in this firmware update, please refer to the Offerings Catalog under Packaged & Split DX Systems | Light Commercial Controls | Smart Equipment Controls.

Norman production lines will begin phasing in this new firmware patch in early 2024. In the interim, implementation of v4.4.0.31 requires either an in-person manual update or an over-the-air remote update using a Verasys SBH300. The installed firmware version on a Smart Equipment Control Board can be confirmed via the LCD Display manual navigation or through the MAP Gateway user interface using a smart device.

Customers with existing units running older firmware versions who wish to upgrade to v4.4.0.31 may do so. Instructions and files for upgrading units are available on Solution Navigator under Resources > Product Tools > Ducted Systems > UPG Tech Service Software, including the firmware package 4.4.0.31.secusb.pkg.

Following the release of v4.0 in January 2020, which introduced additional features, menu structures, and supported applications, it is still recommended that customers update their Mobile Access Portal (MAP) Gateway tools to ensure visibility of Smart Equipment v4.0+ additions.

The MAP Gateway must be on firmware version 5.1.0.355 to view the latest features. Instructions for upgrading the MAP Gateway can be found on Solution Navigator under Products > Commercial Ducted Systems / Light Commercial Controls > Light Commercial Controls > Light Commercial Controls > Smart Equipment Controls.

All 4.4.0.31 Smart Equipment Units manually updated will remain compatible with Verasys and require BACnet communication cards for integration. More information on Verasys is available at www.verasyscontrols.com.

Change-Log Summary

Firmware Updates

• SSE-1347: Increased stack size of the provisioning validation task in factory test to avoid a memory leak.
• SSE-1632: Fixed memory leak in flash statistics server that could cause a boot failure after board restarts.
• SSE-1658: Updated zlib from 1.2.7 to 1.2.13 to address security vulnerabilities.
• SSE-1667: Changed the naming scheme for OTA (remote) packages used on the SBH to the format: [version]_SE-SPU1002-0_remote_ota_update.zip.
• SSE-1731: Added NSW8000 support and resolved an issue where Net Sensor setpoints lost their values after a Unit system change (Imperial to SI or vice-versa).

Application Versions:

• UCB: 13
• Economizer: 4.0.0.937
• 4 Stage: 7
• FDD: 4.0.0.210

Enhancements

• SSE-983: Added functionality to support modulating neutral air HGR. New points Neutral Air ModHGR Enable / NeuAirModHGR-En (default: Disable) and Neutral Air ModHGR Offset / NeuAirModHGR-Off (default: 0°F) have been added to Details > Hot Gas Reheat > Setup, and to BACnet/Modbus/N2. These points are visible only if Neutral Air ModHGR Enable is first enabled via the restore process.
• SSE-1483: Added functionality to support dual fuel heat pumps. New point Dual Fuel HP Enable / DualFuelHP-En (default: Disable) is added to Details > Heat Pump. This point is visible only if Dual Fuel HP Enable is first enabled via the restore process. New point Dual Fuel OAT HP Cutout / DualFuelOATHPCutout (default: 40°F) is added to Details > Heat Pump, and to BACnet/Modbus/N2. This point is visible only if Dual Fuel HP Enable = Enable. New point Reversing Valve Delay / RevVlvDelay (default: 0 seconds) is added to Details > Heat Pump. This point is visible only if Dual Fuel HP Enable = Enable.
• SSE-1252: Updated supply fan tuning parameters for SZ VAV cooling to improve supply fan response time.

Bug Fixes

• SSE-761: Added logic to hide the HeatCool Setpoint Mode when the controller is in VAV mode (FanCtl-Type = Variable Speed and SZVAVEn = Off).
