Victoria Arduino BLACK EAGLE VA388 User Manual

7.8 HOT AND COLD WATER
VALVE
The VA388 is provided with a hot water tap with
adjustable mixer.
In this way the outlet water temperature can be
lowered by mixing water from the heater with
water from the network, thus reducing the levy in
the heater and consequently saving on heating.
For this reason it is commonly called hot water
economizer.
HOW TO ADJUST THE TEMPERATURE
To adjust the temperature, simply use a flat
screwdriver while the water is running.
To decrease the temperature, simply turn the
screw counter-clockwise, while to increase it,
turn the screw clockwise.
3 At this point it becomes much easier to
remove the flowmeter by removing the
underlying screws that bind it to the metal
plate.
WHEN TO INTERVENE
Problems that can be encountered in the econo-
mizing unit are:
1 Failure to deliver water.
2 Delivers only hot or only cold water.
3 Continuous dripping.
4 Erroneous programming.
Cases 1, 2 e 3 are due to malfunction of the valves
so you need to access them and verify that they are
working properly.
The valve may stop operating due to electrical prob-
lems or is not working properly due to obstructions
for example caused by pieces of limestone that
detach from the heater and clog the valve.
If both valves do not work and the classic open-
ing and closing noise is not heard, there could be a
problem with the relay in the electronic board, there-
fore it is necessary to directly measure the voltage
with a voltmeter while water is being dispensed.
