1.9 DHW MIXING VALVE.
e thermostatic mixing valve mixes the cold
water with the hot water and via an internal
wax element, sensitive to the temperature,
automatically controls the temperature of the
mixed water set by the user.
N.B.: for excellent management of the
temperatures, the mixing valve must be set by
the installer at a safety temperature required by
the user.
e DHW output temperature can also
depend on the value set on the boiler, however,
the DHW temperature upper limit value is always
determined by the position of the mixing valve:

knob position 1 = 42°C, 2 = 48°C, 3 = 54°C, 4 =
60°C (as per standard) (the values indicated refer
to a storage tank with water at 70°C).
Any release of the three-way mixing valve. If
a er a long period of inactivity the three-way
mixing valve is blocked, it is necessary to act
manually on the knob positioned on the top of
the same in a way to release the shutter of the
valve itself.

1.10 KITS AVAILABLE ON REQUEST.
• Pump kit (on request).
e storage tank unit
is prepared for application of the pump kit.
Immergas supplies a series of fittings and
attachments that allow connection between
the storage tank unit and domestic hot water
system. The pump kit attachment is also
envisioned on the template.
• Electronic anode kit (on request). Direct
current is made to circulate between the device
and the tank to be protected via a special
titanium anode. Use the free tting on the
storage tank supper ange for installation of
the anode.
