You can control your heating and hot water without any internet connection by using the in-home Programmer and Thermostat(s). The Programmer allows you to schedule both your heating and hot water. Simply set the temperatures you want or when you want hot water, and the heat pump will come on at those times and maintain your requirements. You are also able to make temporary target temperature adjustments on each Thermostat which correspond to that heating zone, or boost your hot water on the Programmer.
