Temperature Sensors; Temperature And Filling Level Indicator - Würth LATENTO XP 500 Notice De Montage

5.5 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.

5.6 Temperature and filling level indicator

When the button is pressed briefly until the display lights up, the temperature and
filling level indicator is switched on for approx. 5 seconds. If the button is pressed
longer until "LONG" appears in the display, the filling level indicator is switched
on for approx. 15 minutes.
Changing the temperature unit
To switch the temperature display
between °C and °F and back, press
the button during operation (the maxi-
mum filling level measured so far will
appear during this process) until the
temperature is displayed with the
new unit.
Battery replacement
If battery replacement should become necessary, the housing must be opened. The
replacement battery is a lithium battery 3.6 V size AA. Ensure correct polarity when
inserting the battery!
After battery replacement, all the segments of the filling level indicator are shown.
The filling level sensor only requires a slight increase in filling level for re-initiali-
sation. This can be achieved through thermal expansion of the water during opera-
tion. In individual cases it can be necessary to top up the water level in the LATENTO
slightly. Following this re-initialisation, the correct filling level is dis played again.
Calibration
During calibration, keep the button pressed with the system switched off until
"RESET" appears in the display. Then press the button briefly again so that an
"X" appears under the "J". After the display has gone out again, calibration is
automatically completed. After calibration, the display initially indicates an empty
tank even when it is full. As after battery replacement, a slight increase in filling
level will lead to the correct filling level being indicated again.
