boiler, etc ...) are not powered-up and are within the rating of the contact.

kitchens) and doors/windows. Mount about 1.5 meters above oor level.
FIXING
Use screws  3.5 mm. Maximum head thickness 3 mm.
When fastening, take care not to over tighten the screws to avoid distorting

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).

Caution
By entering an incorrect PIN code, the thermostat will display Err for an
instant and then re-presents the locked display. After entering the wrong
PIN 3 times, the thermostat will remain locked for 20 seconds with Err
displayed (the display will turn o after 5 seconds to preserve the batteries).
This procedure repeats for any further attempt to enter the wrong PIN.
NOTE
Removing the batteries will not cancel the lock.
If you forget your PIN, use code 513 to unlock the product
