Temperature Sensors - Würth LATENTO 500 Notice De Montage

Note The DHW heat exchanger must only be charged with a pres-
sure of max. 15 bar. The heat exchanger would expand if the
water pressure exceeded 15 bar. The LATENTO might get dam-
aged because of this.
Due to DIN EN 12502, there is a max. chloride concentration
of water of 53 mg/l (warm water) respectively, to be kept.
Otherwise there may be hole-/grid-corrosion in the
heat exchanger.
Pressurised flushing connections must be installed in front of the thermal mixer for
the flushing and for any descaling of the drinking water heat exchanger that may
be necessary. If water hardness exceeds 20° dH (3,57 mmol), we recommend to
install a water softening device to avoid an efficiency loss due to limescale in the
heat exchangers.

Temperature Sensors

Position the temperature sensors into the sensors glands at the level so indicated
in the installation proposal and connect the sensors to the regulation unit. The sen-
sor glands have been dimensioned such that several sensors can be inserted into
one sensor gland.

6.4 Float and filling level indicator
The level indicator is a float inside a guide tube. The
sight glass scale shows the optimum fill level at a given
average storage tank temperature. It thus takes into
account the temperature-dependent change in volume
of the water inside the LATENTO.
