SAFETY WARNINGS
During product installation and operation it is necessary to observe the
following instructions:
1) The instrument must be installed by a qualified person, in strict compliance
with the connection diagrams.
2) Do not power or connect the instrument if any part appears to be damaged.
3) After installation, inaccessibility to the connection terminals without appropriate
tools must be guaranteed.
4) The instrument must be installed and activated in compliance with current
electric systems standards.
5) Before accessing the connection terminals, verify that the leads are not live.
6) In the electrical system of the building where the instrument must be installed,
a switch and a protection device from the overcurrents must be present (for
Thalos Key 230 models only).

The writing will appear when all parameters are set and the END
thermostat returns to normal operation saving the effected modifications.
Models battery powered have a auxiliary input that can be
configured for connection instead of:
- an external temperature probe
- an external contact for the set-point temperature reduction.
Closed external contact allows setpoint reduction of 3 °C
than the set one. Display shows the symbol .
For auxiliary input configuration, see “Advanced programming” on this manual.
• Battery models
In the battery-powered supplied models the display backlighting is normally
OFF and it is enabled (blue colour) entering menu: setpoint modification,
advanced programming, pin enter.
