DHW INSTANTANEOUS PREPARER
The instantaneous DHW preparer is available in the models models MPR.
Here below are indicated the operating regions of the instantaneous DHW preparer versus the temperature of the primary circuit
(DHW temperature of technic side) and the water flow rate of the secondary circuit (DHW withdrawal rate), for different values of
the set temperature of domestic hot water (T"_Set_DHW).
The region of operation corresponding to the alone optional electric heater is indicated with red dashed lines.
WARNING: It is necessary to install on the DHW line between the instantaneous preparer and the mixers of
domestic hot water, of an anti-scald thermostatic valve calibrated at 45°C.
Otherwise there is a serious risk of burning and severe scalding.
WARNING: Make sure that there are no air bubbles in the water supply inlet; otherwise the flow meter will not
work properly. Therefore a relief valve or an air vent should be installed on the mains water inlet pipe.
WARNING: The minimum water flow rate of the secondary circuit (water supply) required for the system startup is
3 liters/min. The maximum water flow rate of the secondary circuit should not exceed 40 liters/min, the system
goes wrong over this value.
