SpaGuts VS300 Digital Spa Controller Kit 10-175-4855 Single Pump Controller Value Kit with VL200 Topside and Smart Sensor Technology, VS300FC5, 54855-01, 5.5 KW HTR

Works like a charm. If you are replacing one be sure to look at the jumpers on the old unit.

I had a minor issue that I caused myself during the installation. The guy at tech support was professional. Walked me through a couple of things to check and quickly found the issue. Never made me feel like I was wasting his time and was 100% there for customer satisfaction.Customer service still exists at a few companies!The spa pack was a perfect replacement.

Was easy to install. Just make sure you follow and read all the instructions. Once it's all set up it's like a new hot tub.

Worked like a dream for about 3 months then started dropping temperature. Submitted a claim, returned to spaguts on 2/1. I have never been updated about the part, I have attempyed to get an update since March, it's currently 4/10 and not a peep. Buyer Beware unless you love frustration, misery and an empty hot tub.

We don’t dislike the product. We just don’t know how to decrease the temperature

I rebuilt our 3 person hot tub from 240v to 120v with this and a 120v pump. I have 24 250w Trina solar panels powering our farm shop. This runs off a 6000w inverter that powers the shop. I have a jasco zwave 40amp smart outdoor switch to schedule it to turn on when the sun comes up. The 40 amp rating is not the breaker, just the heavy duty rating of the switch. That switch runs to the 120v 20amp outlet the tub uses. I got a levitron inline gfi for the tubs' 6 ft power cord. You can also use the gfi that replaces the end of the power cord, or buy a gfi power cord. Don't listen to spa guts, you do not need a hot tub gfi disconnect box for 120v, only 240v. 120v tubs come with a gfi plugin cord from the factory.The smart switch turns on every hour 5 minutes to circulate the hot water through the pump when the temp is below 34 degrees. It does not run on a cloudy days except for that hourly antifreeze mode if needed. I live in a desert so we always have sun and a 103 degree hot tub. I wish spaguts, or rather balboa, had a mode like this to not use the heater and only minimally use the pump at night. But its not spa guts' fualt bc it's a balboa rebadge at a better price.One good thing is it saves the temp and settings every time it turns off and on so that you don't have to reprogram your favorite temp every time it turns off.The jasco/enbrighten switch is great for pools and hot tubs. Its nice to be able to control my hot tub from my phone. I'm not sure how much scheduling the spa guts wifi board similar to this one gives you but I doubt it will be as precise as the zwave home automation platform. Very few things besides Vera and hub zwave work offline without internet. So my schedules will still work if the wifi is down with Vera.

Equipment seems high quality. If doing the work yourself you might have to install jumper cable and move wires. There is no indication of start up procedure. There is no mention of the error code ec or how to get out of economy mode. So keep your phone handy to do some searching. Not difficult, just annoying. I never called, little help on their website.

I was perfectly fit and very happy with it !
