Please also note that if you are simply showing a countdown for people to observe, Kratmel's answer is perfect. But if the 130 is actually controlling the fan's run time, the ideal method of doing this is for the timer to be linked to the fan control output with a little ladderwork. Having 2 separate timers running for essentially the same thing will work, but is not ideal in case the fan output is turned off for some reason. In that case the timer will still be implying the fan is running. cheers, Aus -
Hi Jamie, please read the "Getting Started" topic in the Help files, with particular attention to "Ladder Net' which is a sub heading at the bottom of "Ladder Editor". This will better explain what is going on with your exisiting ladder construction, and the entire Topic is worthy of a full read for your learning curve. As are all the Help files. cheers, Aus
