When the thermostat is on, the digital display shows the temperature. The display can easily be adjusted to the user’s preference.

Electronic Temperature ControlModel DSD601AD has a temperature range of -30°F – 220°F. The model has an adjustable differential of 1°F to 30°F. By comparison, this is a much larger range than our line voltage thermostats. Line voltage thermostats have a temperature range of -30°F to 110°F. They also have an adjustable differential of only 3°F to 12°F.

Plus, our thermostat can display Celsius and Fahrenheit. There is an LED power indicator light as well.

In conclusion, ETCs make it easy to sense and control temperatures from a distance. This helps to ensure properly running HVAC equipment.
