Some users experienced 3.40 OTA update leading to the screen going blank; wall control then recovers to v3.00 upon forced reboot. The primary cause has been corrected; but additional analysis is in progress to ensure this will not happen in the future.

Minor updates:

False G-terminal Alerts could be triggered during the learning process check if the system control reads the status inputs from the furnace and fan coil before they have been set properly.
Fix provided in system control, G-terminal status is updated only after reading the control inputs status event from indoor control boards.
Revised the Capacity Limiting logic to allow for duty cycling of the Greenspeed 3 to emulate a capacity lower than the set minimum.
Resolved issue where cooling demand took a long time (~30 minutes) to start.
Improved Fault Code handling for Infinity® 26 Air Conditioner with Greenspeed® Intelligence and Infinity® 24 Heat Pump with Greenspeed® Intelligence o Fault Codes with differing expansion codes are now considered to be different codes and show up as separate entries in the Last 10 Events screen. o Now storing fault description messages in permanent memory to prevent incorrect messages displayed after a wall control reset. o If an active 127-EQUIPMENT UPDATE FAILURE fault occurs, it will be cleared after the next successful firmware update. o Fixes for mismatched fault code and fault description combinations in the Last 10 Events screen. o System control software has been updated to handle empty fault strings on status screens and refrigerant charging screens.
The defrost on Infinity® 24 Heat Pump with Greenspeed® Intelligence can run longer than 15 mins and will not cause a system malfunction so that heat demand could run afterward.
Removed warning for LLV open on Charging screen.
Help text for cycle counters and run times screens are added for both Air Conditioner and Heat Pump
Utility Curtailment feature when active will get recorded in the Last 10 events screen
Refrigerant charging – pump down statuses were incorrectly displayed. Changes in the pump-down state typically take 5 seconds to reflect the actual state from the outdoor unit; in rapid state change from the ODU, It can take 10 seconds to reflect that state change.
Fixes for range and toggle button-related issues for capacity limiting screens have been made in the system control.
Corrections to Capacity Limiting minimum demand calculations; now applies the minimum demand limit as a part of the capacity limiting feature as opposed to the previous behavior where a minimum would not be imposed.

o Known issues: The outside air temperature range setting can only be set to “Limiting Above” the specified temperature; the capacity limiting feature is not working as expected when the MIN capacity is set to 50%,
Additional updates:
Energy Estimate calculation issues, causing. energy estimates appear to be much higher than expected.
o Energy usage was displayed incorrectly, giving a false reading of estimated energy used. This change is a modification of the conversion of watts to kilo watt-hours (KWH). Under energy tracking, in the view energy usage screens, energy used is now displayed in KWH.
The system control could update the outdoor unit to the same software version if the SD card was not removed after a successful update.
o Added a periodic check of the SD card contents to see if the files are still valid for the update.
Service Valve Subcool Value – displayed value accuracy.
o System control code is changed to display accurate Subcool values.
The operating status on the home screen is not aligned with the actual equipment operation.
o Home Screen equipment operation is now aligned to actual operation.
Blower RPM shows as 0 when the IDU blower is operating.
o The Blower RPM value was outputting 0 on the AC/HP checkout screen, so the AC/HP checkout screen has been updated to output the actual Blower RPM value.
During system installation (learning), system control did not correctly discover the 24VNA624 ODU + FE4ANB005 fan coil combination.
o Corrected a logic error in the learning process that prevented this valid combination from being recognized.
During checkout mode, received the message “Info 104 – Low Indoor Temp Zone 2 Aux Heat” on HP’s and AC’s, cooling and heating mode.
