I have an air handling unit that has 120 volt motor starter. The customer wants a button to press that will shut the unit off for 20 minutes then turn back on, but also once the button is pressed, the button needs to be deactivate for an hour to stop the air handler from being off for extended periods of time. What is the best way to go about this? A few time delay relays?
