Testing it out—you set the thermostat to a temperature, I.e. 74 degrees (Fahrenheit) and insert the temperature probe into the soil or growing medium. If the probe is reading less than the desired temperature it will run the heating pad until the medium is heated to the temperature you want it.
My new replacement unit shows all this in degrees Fahrenheit, and let’s you program the temperature in Fahrenheit. The first “defective” one only showed it in degrees Celsius and could only be set to temperatures in Celsius before displaying the Fahrenheit Temperature.
The new heating pad, like the previous one works, no issues there. Keep I’m mind though it plugs into the thermostat, the thermostat does not set or regulate the temperature of the heating pad. The heating pad will be warmer than the temperature displayed on the thermostat—as the thermostat is only monitoring the temperature of the soil or growing medium. Once it reaches the set temperature it shuts off power to the heating pad.
My older review from earlier this week dealing with the defective thermostat:
I am in the process of returning the combination seedling heating pad and thermostat because the thermostat doesn’t work. The unit I received did not supply power to the heating pad. I had set up everything as per the instructions and kept an eye on it, noticing that the “heating” light never came on with the pad plugged in. So I took a non contact thermometer and checked the pad temperature—it was room temp and nothing more, then plugged in an outlet tester (in the photos) to check the thermostat plug in for the heating pad and there was nothing. I’m assuming it’s not wired correctly and contacted Vivosun’s support via email. I emailed them Sunday and have not heard anything back yet, so I decided to exchange the item through Amazon—which had a very easy and efficient way of handling the exchange—they are sending me a new one which I hope works correctly and I have to drop the defective one off at my nearest Kohl’s store customer service department to be sent back to Amazon.
I’ll have to update this once I get the replacement unit and can better judge the thermostat. The heating pad works very well and I had to manually regulate the temperature to sprout my seeds. It seems very heavy duty for the wattage it works on and should last a few seasons. I know it’s offered separately from the combination set I had ordered.
If it had worked right, the thermostat was easy to set to the temperature on and I like how the probe is designed. The only other complaint I had was that you have to set the temperature in Celsius—but it will display the temperature in Fahrenheit. Some conversion work needs to be done if you want to set it at 80 degrees F for tomatoes.
Had it worked and controlled the heating pad, had Viviosun contacted me back with their advice on what to do (it’s rumored on Facebook they are not responding to emails possibly because of being located in China and not working due to current events), I would have given this a 5 star review and written how well it works. Hopefully I can post that review once I get a properly working replacement.
