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.

love it cycling all night saves electricity

It just works, I got another kind and it was too complicated to figure out. This one just works and works great.

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

I got this because the electric space heater I use in my sunroom just kept cutting on and off and wouldn't keep the room a constant temperature. It is like night and day after I plugged it into this thermostat! Just make sure you turn the high low dial on your heater to the highest setting otherwise it may cut off before it heats to the temperature you set.

It's nice to get something that works like it is supposed to work. We bought the SureStat TS116 Plug In Portable Thermostat Control to control the greenhouse fan. It is well made and the electrical cord, usually a weak point in such items, is heavy and the plugs are good. The thermostat temperature calibration agrees with the hanging thermometer; no adjustment was required. All in all, it is nice, works well, and is a good value.

Reasonable price and great service.
