Insert the batteries into the battery compartment, respecting the indicated
polarities.
CAUTION Incorrect positioning of the batteries (polarity inversion) can
damage the thermostat.
The thermostat is provided with 2 battery thresholds: the rst threshold
indicates that the batteries are low and must be replaced. In this condition,
the display in the o state and a ashing battery icon will show every 5 sec.
After touching the Finder button and turning on the display, the battery icon
will continue to ash.
At the second threshold the thermostat turns o, the output relay will be set
to OFF and it will no longer be possible to make any further adjustments.
In this condition the ashing battery icon can be seen every 5 seconds (until
the batteries completely run out).
