Battery Replacement; Filling - IVT LATENTO XW Serie Instrucciones De Montaje

Changing the temperature unit
To switch the temperature display between
°C and °F and back, press the button during
operation (the maximum filling level meas-
ured 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
and the board loosened. The battery (AA lithium 3.6 V) is on the rear of the PCB.
Ensure correct polarity when inserting the battery, + is on the side where the
cable is connected to the PCB.
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-initialisa-
tion. This can be achieved through thermal expansion of the water during operation.
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 displayed again.
Calibraation
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.

6.5 Filling

After installation the filling level & temperature display must be calibrated
(see chapter 6.4)!
Fill the LATENTO XW with drinking water via the filling and draining valve. Open
the cover for the optional E-heating rod to allow the air displaced by the filling
process to escape.
When using the E-heating rod:
Screw the heating rod as far out of the thread as necessary to allow displaced air
to escape.
