What does the HW-1703H can do for you?

The control range for 1703H is -50℃ ~110 ℃ /  -58℉~230℉, most of the user choosed it for protecing the equipment,machines works in a good ambient temperature or green house.

HW-1703H is good for controlling a constant wide range temperature, such as if you want to keep the temperature stay from 20C to 35C degrees, it can turn on the heater when temperature lower than 20C and turn on the cooler when temperature higher than 35C.

The maximum loading of 1703H is 5amp, if you need to load a more large currents device, you can extend the controller with a intermediate relay.

The 1703H has a treble way output,way one for controlling heating, way 2 for controlling cooling, way 3 for controlling alarm or extend to other device when temperature is out of controlling. way 1,2,3 can work together in the same time.

Fast to learn the difference between each temperature controller.
