Yes the 312 has one for a chiller. The 306 are both controlled at the same time on the same temps. At least I don’t see anything in the booklet stating otherwise.
So far after the first night no issues with the 306 so hopefully it was just a faulty INKBIRD. I did order a compact 100 watt heater to put in the tank. I just hate putting more in the tank. It’s already crowded in there but it’s better than killing everything. I don’t have room for a sump so EVERYTHING is in the tank or hanging on the back.
