Before commencing any work on the electrical connections, you must rst disconnect the thermostat
from the mains. None of the 230V connections must be live until the installation has been completed
and the housing is closed. Only qualied electricians or authorised service sta are permitted to open
the thermostat. Disconnect from mains supply in the event of any damage to any buttons.
There are parts that carry mains voltage behind the cover. The thermostat must not be left unsupervised
when open. (Prevent non specialists and especially children from gaining access to it.)
If the thermostat is used in a way not specied by the manufacturer, its safety may be impaired.
Prior to setting the thermostat, it is neccessary to complete all required settings described in this section.
Never remove this product from the electrical baseplate. Do not use sharp tools to push any button.
CAUTION! Installation and connection should only be carried out by a qualied
person and in accordance with national wiring regulations.
