5 Operation and configuration methods

Pressing the keys and , at the same time for at least 5 seconds will allow
access to the configuration menu.
In the configuration menu, pressing the key
to the required item and once this has been selected, use the keys
change the setting. It is possible to exit the configuration menu by pressing
any time, or wait for the timeout of approximately 60 seconds.
The configuration steps are suggested in the circular sequence with which they
appear on the display:

5.1 Key Lock

The "Key Lock" function allows blocking the keyboard in order to avoid acciden-
tally changing the set point (desired temperature value) and/or the operating sta-
tus of the thermostat. The keys
"OFF/ " and the symbol , ad indicare rispettivamente la condizione del bloc-
co disattivato/attivato.
Note: activating the key lock does not prevent access to the configuration menu
which is necessary in order to set deactivation.
Factory settings: OFF

5.2 Operating method: Summer or Winter

The keys and will view alternately the symbols
operating method of the thermostat (summer=conditioning or winter=heating,
respectively).
Factory setting: Winter ( )

5.3 Reduction

The "reduction" value is an absolute value that will be added to the set point in
order to obtain a reduction in consumption, usually requested at night. The "reduc-
tion" value is viewed with the sign "- (minus)" if the thermostat operates in
"Winter" mode, and the sign "+ (plus)" if the thermostat operates in "Summer"
, it will be possible to select/pass
and
and will show the alternate wording
and , to show the
mode (indicating that this value will be a subtracted or added to the set point
according to the operating mode); this value will be viewed together with the sym-
bol for night time reduction. Use the keys
-0,5 to -5,0 °C if the thermostat is in "Winter" mode (or from +0,5 to +5,0 °C if the
thermostat is in "Summer" mode).

hold" value is a temperature value and below this the thermostat will activate an
output relay even if it is switched off (operation status OFF). Use the keys
to regulate from +2,0 to +10,0 °C.
Factory settings: 5,0 °C

5.5 Thermal compensation

In cases where it was not possible to assemble the thermostat in an ideal position,
i.e. if the thermostat is on an external wall, near a fireplace, etc., there could be a
difference between the temperature picked up by the thermostat and the actual
room temperature. In these cases it is possible to set a thermal compensation
(example: the difference between the actual room temperature and the temperature
shown on the thermostat is 2 °C, i.e. the room temperature is shown to be 2 °C
higher: the compensation value will be -2 °C).
The set value will be viewed with the wording " 0.0". Use the keys
regulate from -5,0 to +5,0 °C.
Factory setting: 0

5.6 Thermal Differential (hysteresis)

Thermal differential is the difference between the set temperature value and the
actual temperature that switches on or switches off the system. Adjusting the ther-
mal differential to the type of system will avoid it coming on or switching off con-
tinuously; high inertia systems (for example systems with cast-iron radiators) need
a low thermal differential value while low inertia systems (for example fan-convec-
