Amazing how accurate this device is. Totally satisfied. Great product..

This is one of the simplest pieces of equipment that I’ve had the pleasure of installing in my grow house. I got the pre-wired cooling version and from start to finish it was pretty much a no brainer.

I had a couple of follow-up questions and I found that customer support/tech-support was extraordinarily helpful, knowledgeable, and easy to work with.

In short, in my experience, this is something that I recommend highly.

I ordered a "greenhouse" control from a different co. It was digital with what they didn't mention was 3 settings temp then high low differentials 2 alarms pictures to set it up with Celsius, fahrenheit did pop up but couldn't figure it correctly company asked where i purchased, replied i just need setting instructions It went back! This one is perfect it has a coiled wire on top, no running a wire to snap or hang wrong, twist a simple dial to the fahrenheit setting plugged the heater in plants are warm. I try so hard to by US products this company is my go to from here on!

This thermostat is working well with a fan unit that I purchased from another company. Paid more for the fan unit and wish I had purchased it from ACF too.

This device works as advertised, and maintains accurate temperature control.
