Click the ECT Zone Hi. Change top line to 210
That will give you 300s of on time at your set speeds at your set temps.
You can fine tune it a lot more for different runtimes for different temps
Open the 'Run Time Zone'
Change the top '300' too '180' and it will only now run for 180s when you cross the corresponding ECT Zones. You have 5 of these you can set.
