Note: in heating mode (winter), if the instrument is off, it adjusts according to the
antifreeze temperature Toff in order to prevent the system freezing.
Toff can have values from 1 to 50 °C or be excluded; in this case any minimum
temperature is guaranteed.
Occurs in case of probe failure.
In this case the adjustment is inhibited and the relay contacts
remain in NC-COM position.
Occurs for the following values of measured temperature:

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 protection device from the overcurrents must be present (for Klima LCD 230
model only).

If the keypad lock is active, pressing one key appears LoC
and the password is required. If it’s properly inserted the
keyboard is unlocked for the next 30 seconds.
Klima LCD has an auxiliary input that can be configured for connection instead of:
- an auxiliary temperature probe. In this case the temperature value measured by
the external probe is showing on the display and used for regulation.
- 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.
