I wanted to use a program to have the fan (on/off switch) run after using the shower. Usually we turn off all the bathroom lights including the fan once showered. I found that moisture was not escaping the room during the period the fan was on during showering. I wanted the fan to run 15 minutes longer after the shower. Thus the need for a timer program. The goal was after showering and leaving the bathroom, I wanted the fan to continue running without the need to revisit the bathroom to turn off the fan. The fan I am using is a in ceiling typical bathroom fan integrated with the rest of the house as an on/off switch.
Using the two stage program has solved the issue. Once the fan is switched off, there is a short delay and then the fan turns back on and runs the program for 15 minutes. I wish there was not a short delay, where the fan would remain on and runs the program. However not a big issue. I did not want a program starts the timer once the fan is turned on. There are several individuals using the bathroom who take different lengths of time showering, I did not what to cut the fan off while someone was in there. Basically I wanted a run time of 15 minutes after you left the bathroom.
Thanks again all.
