Control your heating system form the touch of a button on your iPhone. Save the sim card number of your iHeat DUAL control unit, enter the length of time you require your system to run, then just press the Boost Heat button on the app. A message is sent to the unit and the heating is activated. Simple !
If your Central Heating and Water Heating are controlled separately, you can now control them both from the app as well as turn your heating or hot water on and off whenever you want, from wherever you are.
