TopDryL16_R3_0_P - Fan/Heaters individually selectable, Customer Data Access routine added, Plenum Temp logged in Dump history, acknowledge "Stop" command from HMI,  freeze warning, return to grain sensor offsets, F/C switching, Grain Temp setpoint visible only in Time & Temp mode (main page), fan aux contact failed to close lengthened to 4s to prevent nuisance alarms, allow manual dumping of grain during high plenum alarm ONLY after acknowledgement. Bug Fix: PLC Date reverts to 1998 if powered off for prolonged period, which causes the HMI to show blank alarms and lock up after v11 firmware release. Added logic to change year to 2022 if it reverts to pre-2000. NOTE: Must be used with HMI version TopDry16_P7S_R3_0 or TopDry16_R3_0_C or newer. 

TopDryL16_R3_1_P - Bug fix that prevented the dump history from logging information. NOTE: Must be used with HMI version TopDry16_P7S_R3_0 or TopDry16_R3_0_C or newer.

TopDryL16_R3_2_P - Minor update to extend the allowable time for the air switches to close before triggering the Airflow Not Detected alarm. This change is helpful if the fans are slow to come up to speed. Example - Quiet TopDry with a VFD for the blower motor. 

TopDryL16_R3_3_P - Updated to accomodate Series C controller. Firmwware v35 is compatible with Ser A, B, and C controllers.
