ZEUS SUPERIOR
- GAUDIUM MAGNUM (6) 
This device is fitted between the cold 
water inlet (inlet) and the safety valve 
group (outlet). 
Inside it works an electrovalve that in 
stand-by condition allows the water 
passage through a flow limiter (1) (10 
l/min for versions 21 and 27, 12 l/min for 
version 24) 
When the electrovalve (3) is supplied the 
water flows trough a supplementary 
passage through a 6 l/min flow limiter (2) 
- Operation 
The valve is electrically enabled (230 VAC) setting the switch “Gaudium Magnum”, located on 
the control panel, on position  . 
It starts to work when the limit thermostat of max flow (3), fitted on the storage tank, detects a 
temperature upper 50 °C. 
When the temperature gets down under 41 °C, the limit thermostat of max flow (3) 
automatically deactivates the valve (3). 
When the storage tank temperature is high, this system permits to have an high domestic hot 
water flow rate. 
Instead when the temperature gets down, the hot water flow rate is limited in order to restore 
rapidly the hot water temperature. 
Re-setting Gaudium Magnum switch on “0” position, the valve (3) is always deactivates. 
N.B.: in order to activate the “Gaudium Magnum” operation, the adjustment knob of domestic hot water 
temperature must be adjusted from 6 to 9.
