After I put it TO the test in my Industrial and Scientific workplace, I was pleasantly surprised by how well this thermostat worked. It was easy to install and calibrate and has been keeping our equipment at a consistent temperature ever since .The low voltage feature also gives me peace of mind when it comes to safety. The only downside I've found is that the instructions could be a bit clearer for those unfamiliar with wiring. Overall, a great investment for anyone in need of a reliable and efficient control option..
