EV DHW

EV3 DHW is a compact solution for controlling DHW heat-pump heaters, managing stratification inside the tank and the anti-legionella function.
It is equipped with an electro-mechanical relay enabling direct control of medium-power compressors, thus avoiding the use of contactors.
Available with LED display, both in the 74×32 mm format (EV3 DHW) or in a larger format with modern design and extra-bright display (EVJ DHW), it has capacitive touch keys and a completely flat IP65 front making it easy to clean.
Upon request, some models can be equipped with Wi-Fi connectivity so it can interact remotely with the unit through the EPoCA® cloud platform. From PC and mobile devices it will then be quite simple to display any logged data (in table or graph form), to configure parameters and to receive alert notifications.
