Whether in new or existing buildings, the DeltaTherm® PV MAX combines Power-to-Heat and heating control. It detects excess PV current reliably and calculates the power available. Furthermore, it distributes the current available in a modulating manner to up to 3 electric immersion heaters with a total power of 9000 W, controls an SG-ready heat pump and a charging station for electric vehicles as needed. Alternatively, electric heatings with room thermostat up to 9 kW can be controlled in a modulating manner. Numerous optional functions can be activated and heating circuits controlled with extension modules. 2 further loads with constant powers up to 30 kW can be controlled via auxiliary relays.
