It is absolutely possible. I've been fiddling with these, trying to come up with a good trade off. I've put them where 'good' settings are in the lower half for my test setup, which admittedly will probably not reflect a 'real' setup in the slightest (a peltier plate, with pretty fast heating and pretty slow cooling). But it is better to err on the safe side.
By my calculations, if you use 999 / 99, the control should be pretty fast for the intent, but I'd more than willing to change this if empirical data shows otherwise
The 'weight' will in this case need to be a multiple of 2, so I'd need to halve it. That is no problem, to do though. I'll try to do that as soon as I can (tonight if at all possible). I'll let you know. If at all possible I'd like the full range to be usable (i.e. be able to cover as many possible setups as possible). It is better to err on the safe side though (even if your system won't react as fast as it could be).
Have you have done actual testing? That is used the hardware to control actual mash temp? In that case I'd be very interested to hear all and any experiences! Does it work for you otherwise? I'd love to see a picture of or just a description of the setup you use. All feedback could be helpful in making this firmware better
You say 3-4 L flow, that is per minute I assume? I does seem like a little much to me (but I really don't know), if your setup permits it (i.e. it does not compact the bed), then that might be fine.
Thank you for your interest and feedback!!!
