0.30 Released OCTOBER 23, 1998
------------------------------------------------------------
1) FLAME TIME OUT IS NOW 10 SECONDS. THE IGNITOR SHUTS OFF IN ABOUT 7.5 SECONDS.
0.29 Released OCTOBER 22, 1998
------------------------------------------------------------
1) ELIMINATE THE DEISEL OPTION -- FORCE THAT FLAG TO ALWAYS BE RESET. THIS CAUSED A 36 SECOND FLAG
TIME OUT WHICH THE HARDWARE IS NOT SETUP TO ACCEPT. IF DEISEL OPTION IS REQUIRED AT SOME LATER
DATE -- WILL HAVE TO MODIFY SOFTWARE TO REDUCE FLAME TIME OUT BACK TO 12 SECONDS MAX OR
CHANGE THE HARDWARE.
2) DEFAULT FAN DELAY = 0 SECONDS ( FOR SLAVES )
0.28 Released August 24, 1998
------------------------------------------------------------
1) CREATE O / noO FLAG -- FOR EITHER IGNITOR OR HOT SURFACE IGNITION -- WHEN SET THIS IS USED FOR A
HOT SURFACE IGNITION SYSTEM -- SO THAT AT THE END OF THE PURGE DELAY THE IGNITOR COMES ON FOR 5
SECONDS BEFORE THE GAS VALVE TURNS ON. NOTE: I DID NOT USE I / noI BECAUSE IF THIS SOFTWARE WAS PUT
ON AN OLD DRYER -- IT WOULD DEFAULT TO noI -- IF THEY DID NOTHING. SINCE H / noH IS ALREADY BEING
USED FOR HUMIDITY -- I JUST USED O.
2) WHEN THE " O " FLAG IS SET -- AFTER THE 9 SECOND IGNITOR PERIOD THE IGNITOR DOES NOT TURN OFF
3) IN THE " O " MODE A FLAME OUT CAUSE THE GAS VALVES TO GO OFF FOR 5 SECONDS WHILE THE HOT
SUFACE INGITION COMES ON. THE WAY I DID THIS WAS TO RESET THE PURGE TIMER TO 5 SECONDS -- SO ON
THE DISPLAY THE " PURGE " COMES UP -- THIS WAS THE EASIEST WAY TO ACCOMPLISH THIS.
4) CREATE d / nod FLAG -- FOR DIESEL FIRED SYSTEM. THIS SYSTEM HAS NO PURGE DELAY ( ACTUALLY 1
SECOND PURGE ) AND A 36 SECOND FLAME OUT TIME.
?????????????????????????????????????????
SHOULD THERE BE A LITTLE MORE PURGE DELAY --- SAY 5 SECONDS INCASE SOMEONE ACCIDENTLY SET THE
WRONG FLAG.
5) IF THE OPERATOR SET BOT THE " O " AND " d " FLAG THE " d " FLAG WILL NOT SET.

0.26 Released April 29, 1998

C.23 Released OCTOBER 29, 1997
------------------------------------------------------------
1) FIXED PROBLEM WHERE IF BOTH THE MASTER AND SLAVE HAVE THEIR OWN INDEPENDENT ERRORS -- THE
SLAVE DOES NOT FLICKER
BACK AND FORTH BETWEEN IT ERROR AND THE MASTER ERROR -- SLAVES ERROR HAS PRIORITY ON THE
SLAVE UNIT AND THE MASTER HAS PRIORITY ON MASTER UNIT.
2) IF THERE IS AN INCONSISTANCY BETWEEN MASTER AND SLAVE ( ERROR 9, 10 OR 11 ) -- THE MASTER TRIES
RESENDING THE IGNITOR COMMANDS 50 TIMES AND RECHECKING BEFORE ISSUING THE ERROR
