I recently swapped out the cheap Hygger heater controller for an Ink Bird unit and I noticed that the temperature range in my tank increased almost 3x. With the cheap Hygger controller I had a temperature range of ±0.4deg from the set point and now its closer to ±1deg from the set point.
Does anyone know if this is something I can adjust? If not then this controller will be relegated to backup and I'll be sticking with the Hygger unit. In the graph below, you can see exactly where I swapped the units at about 09:30 last night.
