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. ## Features - Lightweight ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B015F4VFGI | | Brand | VIVOSUN | | Brand Name | VIVOSUN | | Colour | Green | | Country of Origin | USA | | Customer Reviews | 4.5 out of 5 stars 5,433 Reviews | | Display Type | Digital | | Model Number | 330101 | | Part Number | 330101 | | UPC | 742920469641 | | Voltage | 230 Volts | ## Product Details - **Brand:** VIVOSUN - **Colour:** Green - **Display Type:** Digital - **UPC:** 742920469641 - **Voltage:** 230 Volts ## Images ![Digital Seedling Heat Mat Thermostat Controller 68-108 - Image 1](https://m.media-amazon.com/images/I/71iyXKtPjVL.jpg) ![Digital Seedling Heat Mat Thermostat Controller 68-108 - Image 2](https://m.media-amazon.com/images/I/81RvryRADGL.jpg) ![Digital Seedling Heat Mat Thermostat Controller 68-108 - Image 3](https://m.media-amazon.com/images/I/71gOMPXr3jL.jpg) ![Digital Seedling Heat Mat Thermostat Controller 68-108 - Image 4](https://m.media-amazon.com/images/I/71I0A-9jcML.jpg) ![Digital Seedling Heat Mat Thermostat Controller 68-108 - Image 5](https://m.media-amazon.com/images/I/71TatSy6wRL.jpg) ## Questions & Answers **Q: how to switch from °F to °C?** A: Hold down on the up and down buttons at the same time **Q: how many mats can be connected to this?** A: I have used these with a power splitter outlet into 2 mats and they work fine. The controler applies power till the programmed temperature is achieved then shuts off. Unit will cycle to maintain temps. I've heard the mats burn out frequently but with a controller I've never had a problem. I usually set for 54°F and tomatoes, peppers, tobbacco, leeks love it some plants pop up in 24 hrs. usually 2-3 days. A small low velocity fan will prevent damping(mold/mildews). Do not shut off heat and fan or damping will take hold in less than a day. And do not use anything other than sterile medium for seedlings/starts No fertilizers for couple weeks and definately no contaminates azomite will introduce spores/damping. **Q: Is this a thermostat with a mat or does it work with any other mat?** A: It is just a thermostat. It works with anything heat outputting, like a heating lamp. The probe senses the temperature and turns the power on or off to whatever you plug into it. **Q: Is the probe ok with saltwater ??** A: Instructions state "do not immerse temp probe in liquid" so no . ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy use *by P***E on 17 March 2026* One outlet needs a splitter Easy operation ### ⭐⭐⭐⭐⭐ Excellent Thermostat for heat mats. *by N***S on 1 April 2026* I am very happy with these thermostats.
