Minimum run time setting
For oil/diesel fuelled boilers/heaters (boats/remote homes) it is important that the boiler runs for at least 30 mins when commanded to avoid the combustion chambers from soothing/clogging up. In a similar mode as your current ‘Output Delay’ it would make your product more useable on a wider range of heater types if you also had a ‘Minimum Run Time’ setting (0-60mins). This would mean that if the roomstat has given a temperature driven ON command a few minutes before a day/time programmed off command, then boiler could run on for the preset time and help service life of the boiler.
