About HW-1703W Temperature Controller:
What does the HW-1703W can do for you?
1703W is the WIFI model upgraded from 1703A, the control range for 1703W is -50℃ ~110 ℃ / -58℉~230℉, most of the user choosed it for a low range temperature controlling such as water Heater, air-condition cooler.
Download the App from Google play or Apple store, connect your controller with WIFI, you can control and monitor your device online, the App will alarm you when your device is out of controlling.
There has 2 optional load for those 2 model, they are 5amp and 10amp, if you need to load a more large currents device, you can extend the controller with a intermediate relay.
1703W series controller only has a single way output, means you can only connect it with a heater or cooler for controlling the temperature at one time.
Fast to learn the difference between each temperature controller.
