i have a problem with using timers in unity pro. the scenario is as follows, tank fills to 240 inches then fill stops, starts agitating for 2 minutes at 20 hz, when that times out it waits one minute then agitates reverse for 5 minutes, then stops and waits for temp to reach 150, as soon as temp reaches 150 process vavle opens and drive agitates at 10 hz till tank level reaches 50 inches. then it waits one minute and restarts the process over again. i cannot for the life of me get these timers working right, i've tried "tof" and "ton" everything i try stops and doesnt restart or wont start at all.... anything you could offer me would be greatly appreciated
