A while I got myself a qmaster lite to control the temps of my smoker, it works pretty well but it does have one flaw, when I lift the lid to do anything to the meat etc obviously the temperature drops in the cooking chamber. This causes the fan to come on when really it's not needed as the coals are just as they need to be for the temperature I want, this action of the fan coming on causes the coals to get hotter and the temp overshoots.
If I could add in a means of stopping the fan from coming on for 10 minutes or so after I've opened the lid, to give the cooking chamber temp chance to get back to where it was I think it would work a lot better, at present I have to unplug the fan and try to remember to plug it back in which is far from ideal.
In an ideal world what I would like would be something whereby I can press a button and that would activate a timer relay which would break the circuit to the fan for a few minutes.
I'm guessing it might be possible to use something like this: DC 5V 12V 24V Digital LED Cycle Timer Delay Time Relay Switch but How exactly I could get it working is a little beyond my electronics knowledge... Can anyone help me with this perchance?
