This review is on the new IPB-16S pre-wired Digital Home Brewing controller.I’ve looked at a number of drawings on doing a DIY for a PID controller but stayed away from the project because of not feeling comfortable in following the schematic drawings. So, when I saw the IPB-16S controller it appeared to be the solution to my need.Received the unit two days after ordering and was able to brew with it a couple of days later. What’s cool about the controller, it is definitely plug and play, the only modification I had to make was installing mounting screws and setting the mash temperature. The unit worked great maintaining the set temperature for my HERMS for home brewing. I have a small pump to recirculate the hot water in the HERMS and it was nice to have the pump control alongside the heat temperature control, very convenient.Would like if the input supported 20A @ 120V, with the higher amp rating I could also use to control one of my brew kettle DIY 2000-watt heat sticks. Once I set the mash temperature it maintained that set temperature for the hour log mash schedule, no hiccups and no chasing a temperature.The units fit and finish looks and feels great with a heavy-duty quality metal case, switch, two receptacles, electrical cord and temperature probe input. Overall the look and feel of the product is high-quality. The cord is very heavy duty measuring 42 inches.The unit is grounded, but I would like to see ground fault protection, if that’s possible, rather than have to plug it into a GFCI outlet for protection. The short cord or GFCI protection was not an issue for me because my 120v GFCI source is only a couple of feet away.I’m not sure if the probe is water proof, read somewhere that said that it is, and, in another post, it said it was not. During my BrewDay I did not have any issues with the probe submerged in water. If and when the included probe fails, I will purchase a probe that clearly states it’s water proof, but on the positive side the cord is 6 feet long.A great purchase and well recommended, saved me time and maybe money, if I were to build my own PID controller. Lastly, I own a couple other types of Inkbird controllers that I have purchased over the last few years and all are great quality and are all still working.
