The ACQUASOLAR smart control unit allows you to get the most out of your DHW (Sanitary Hot Water) solar collector. This switchboard will give you remote access from your Android device (tablet/smartphone) to the following functionality:(a) Know the temperature of the DHW, the outside temperature, and the historical evolution in the last hours of both values.(b) You can define time intervals in which you want to have the guarantee that you will always have DHW at least at the minimum temperature that you decide.(c) The ACQUASOLAR control unit will monitor your DHW and activate the electrical resistance as a complement to your solar collector only when necessary.(d) You may -additionally- activate the electrical resistance at any time, which will deactivate itself after two hours.(e) The ACQUA system will allow you to minimize the consumption of your electrical resistance as a complement to the DHW solar collector. You will be guaranteed to have hot DHW when you need it without wasting energy when you do not require hot DHW.(f) You will be able to verify the efficient use of the electrical resistance through the usage statistics that the system itself offers you from your Android device.
