The VIVOSUN 1500W Digital Temperature Controller has good specifications and is easy to program. I am using it to control a 1300 watt space heater. It has been running for over a week, turning the space heater on and off several times a day, without any trouble. Of course, the best test will be to see how well it stands up to long term use. But for now I am fully satisfied with this controller and would recommend it without hesitation.

Fairly easy set up and worked perfectly in my greenhouse to turn on the heat when it got cold. However, one day it just did not work any more after about 30 days being installed on a 12 amp heater. I still count myself lucky however because it was discovered on a mild morning where the temp was in the 40's. The week earlier it was in the teens and 20's we would have lost all our plants if it had died then. I would not purchase again based on the chance that we could have lost all our plants in the greenhouse.

A nice heavy duty looking thermostat that I connected to my cabinet sauna to control the heater. The controller also can control cooling systems and fans.I quickly learned that though my sauna can not reach the recommended temperature for therapuetic results.

If you have a greenhouse and you control the temp this is awesome . Easy setup

This controller contains a small fuse that will burn up if you run too close to the rated load for an extended period (like if a heater runs for a while on a cold night). The fuse is not replaceable and can pose a fire hazard when it fails. Such a fuse should not have been used in this product. This is a manufacturing defect. Unfortunately, because it is unable to perform as advertised without possibly catching fire, i cannot recommend anyone buy this product.

I use to control a window portal fan. when the room is too hot, differential kicks in on my AC Infinity Fan Controller, also this turns on fan. Fan runs until space is cooled. If temp drops too low, my AC Infinity fan sensor turns on fan... Imagine 75 degree setting with window built into fan controll of 1.1 degrees. it reads 76 and turns a cold stream into a small area. the AC fan control exhausts to room until room is cool. this inherintly shuts down fan... OMG:)

I like the ease of use and convenience of this thermostat unit. I am however concerned about the quality and safety of the product longterm. Mine lasted about a year and the fuse in it burned up like others. These should probably not be rated for 1500w or even 1200w for that matter. Mine quit a month after upgrading my heater to a radiator style oil filled heater that pulls 1200-1300w. I would keep a spare on hand in case this dies on you and its detrimental to your usage (precise hvac in my case). I am looking for another brand that will last meanwhile. Vivosuns other products like the 9" tent fan that oscillates typically don't last either...

Item works good, instructions are terrible. You will have to try adjusting the cool temperature offset to maximum delta T. And then set it for heating at whatever setting you want. Then it works as it should.
