VIVOSUN Digital Heat Mat Thermostat Controller, 40–108 ºF 1000W for Reptiles, Seedlings, Germination, Incubation and Fermentation

I am very happy with these thermostats. I am using them to control Vivosun heat mats.. The combination works flawlessly. The temperature control is acceptable and with the controller, very adjustable. They do not heat quickly. For me, that is ideal. They do not draw a lot of power while warming, and seem to not take much electricity to maintain the temperature once it reaches the setpoint. That is excellent. I have used Vivosun heat mats and thermostats in the past and expected them to still be high quality. That is exactly what I found. Very easy to use. I have never had any problems with them and they get water all over the mats almost constantly with timed watering. No issues at all. I keep the thermostats elevated out of the water spray, so the critical connections always stay dry. I am a fan of Vivosun products and will purchase them in the future.

I read some reviews saying the thermostat did not read true. I took a chance and bought one last month for my seedling heat mat then ran a test when I got it. I set it to 80 for my mat with a cup of water on it. Put the thermostat thingy in the water and waited testing every so often. The thermostat read consistently .2 higher than my instant thermometer so good there. It shut off at 80.2 and turned back on at 79.5 - perfect. I was happy so I bought the second one I needed and it tested the same. I am very happy with these

works pretty good , although mine all of a sudden stopped putting out Fahrenheit , it only gives me Celsius . so, I have to do conversions to use.

Using to set temperature on heat mat for raising puzza dough. Works well.

Received mine two days ago and promptly hooked it up only to discover that the LCD readout only functioned partially. As it stands I am unable to see the actual temperature readings or know for sure if I have set the correct temp on the unit as only parts of the number grids will display but not enough to know exactly what number you are setting. Aside from the bad display, the unit seems very basic to operate and the included instructions were sufficient. Like many others, I must have gotten a bad unit. EDIT 01/01/2017 I was contacted by the seller shortly after posting my original review and they offered to replace the defective unit for me. Upon receiving the replacement unit with expedited shipping, I am happy to say that the display is working perfectly and it appears to be maintaining the temperatures much better too. I'm very satisfied with how things were address and resolved.

Compact, rugged box with 6 foot long temperature sensor probe wire and heavy duty power cord. Three button controls make for easy setup and adjustment In most applications a power strip or other power splitter will be needed to service an installation, since the box has a single (heavy duty) power outlet socket. Good quality unit.

Use these in our greenhouse operations for spring planting

I'm using this device for my worms, only word of advice I have is to make sure your probe is in the right position, at one instance I installed the probe in the worm bedding, the probe slide up and of course, the mat under the bin kept hot, good thing I noticed and corrected the probe position to right under the bin where the mat is, not perfect but does the job to keep worms around 70f.

One outlet needs a splitter Easy operation
