In case of a Chronothermostat room temperature probe fault, the display activates fault E92 and the symbol
. Heating is turned off.
Restoring factory settings
Important! With this procedure all the Chronothermostat parameters will be restored to the factory-set value,
except for the time. Therefore it will be necessary to repeat the procedure for the daily automatic programme and

INSTALLATION
The Chronothermostat must be fi xed to the wall
at a height of approx. 1.5 m from the fl oor, in a
place away from doors, windows or heat sources
that can affect the room temperature. Disconnect
the power to the boiler before carrying out instal-
lation. Remove the front of the Chronothermostat
by prising with a screwdriver at points A and B.
Then fi x the back of the Chronothermostat to the
wall with the set of screws supplied, making sure
to pass the 2 wires inside the middle hole: remove
the cover protecting the relay contact and make
the electrical connection.
Refi t the front of the Chronothermostat.
