ZEUS SUPERIOR
Depending on position, this allows:
Main switch
(IG)
0
-
circuit not powered
-
d.h.w. and CAR function
(optional)
-
d.h.w. and central heating function.
3-position switch
Max flow limit thermostat
(TP)
It is screw up on the external wall of the storage tank.
With the Gaudium Magnum switch (IP) in
position, powers the
solenoid valve of the Gaudium Magnum device (EP) when measures a
temperature higher than 50 ºC.
Interrupts electrical supply when the temperature falls below 41 ºC.
Clicson double-
contact thermostat
Overheat. safety device
(TS)
When the safety temperature (100 ºC) is exceeded, this interrupts power
to the main coils of the gas valve.
It is positioned on the flow pipe at the primary exchanger outlet.
Clicson double-
contact
thermostat
LOADS
3-way electric valve
(VD)
Deviates the flow of water of the primary circuit from the heating circuit to the boiler coil
and vice versa.
It is powered by the modulation board.
Circulator
(MP)
Permits circulation of water in the primary circuit.
This is powered by the modulation board whenever there is a demand for d.h.w.,
heating or antifreeze.
Fan (MV)
Ensures the flow of air inside the sealed combustion chamber and the exit of flues produced
by combustion.
Powered by the modulation board.
Gas valve (V/G)
(main coils)
This is powered by the ignition control unit when the burner has to be ignited.
Permits flow of gas to the burner.
“Gaudium Magnum”
electro valve
(EP)
Permits to increase the maximum available flow of domestic hot water
(see Gaudium
Magnum operation).
Powered when the “Gaudium Magnum (IP) is in
position and by the maximum flow
limit thermostat (TP)
“Gaudium Magnum” (LP)
operating indicator
Displays on the control panel the operation of the “Gaudium Magnum” function..
Is a green lamp connected in parallel to the “Gaudium Magnum” solenoid valve(EP).
Ignition control unit
(IGN. UNIT)
Controlled by the modulation board when the burner has to be ignited.
Controls the devices needed for ignition
(gas valve, ignition electrodes)
and flame detection
(ionisation electrode).
Ignition electrodes
(E1 - E2)
These provoke an electric spark that ignites the air/gas mix.
They are controlled by the control unit ignition transformer (IGN. BOARD)
Modulation board
This is powered when the main switch (IG) is positioned in
(summer or CAR)
or
(winter) (see modulation board operation).
