@oldmate32: I will check with Samer about this in the app. I am pretty sure the firmware accepts the range to 600. In the meantime, you can adjust option values on the controller directly using buttons. Specifically, power off the controller, right after powering it back on, press and hold the third pushbutton B3 and continue holding it until the display says ‘Setup Options?’. Click B3 as many times as you need until you see the Master On Delay or Master Off Delay option. Use B1 and B2 to adjust the numbers. When you are all set, press and hold B3 until the controller reboots itself. The values are now saved.
