I’ve replaced the FTSS controller for my 7gal unitank with the spark 3. The stock controller struggled to keep the temp +/- 1 C of the setting but brewblox/spark keeps it within an impressive .1
I’m very happy with the plot from a temp perspective, but looking at the state of the heater and cooler actuators makes me wonder if there’s more tuning to be done. With an ambient temp of roughly 18C and a setpoint curve going from 10C to 12C over 24h, I’m thinking ideally, the cooler shouldn’t have to turn on at all. Am I being too picky, or can this be improved?
