This app is only for the HPV Series heat pump ventilation system. You would have purchased this system from Total Home Environment, for your well-insulated and airtight newbuild or renovated home in the United Kingdom.
It means that you can remotely manage the comfort and efficiency of the system, should you need to. You can control space heating, ventilation levels, cooling and if the HPW300 is installed, hot water preparation. You can also monitor humidity and Carbon Dioxide levels where sensors have been specified.
