INTERVENTION DELAY (ADJUSTMENTS OF THE START&STOP TEMPERATURE HYSTERESIS)
When the room temperature is reached, there is a waiting time for intervention to prevent the equipment from suddenly turning on/off as
the room temperature drops/rises, for example, when a door or an external window is opened. This waiting time therefore allows you to
be sure that the room temperature has actually dropped for a certain time inside the room (for example 5 minutes).
There is also a temperature threshold beyond which the equipment reacts to in the event of switching on and off and this is called
hysteresis. The NEGATIVE hysteresis identifies the temperature delta, outside of which the appliance must switch back on.
The POSITIVE hysteresis identifies the temperature delta, outside of which the appliance must switch off.
The hysteresis are both included in the user menu.
Example1: With the product switched on, POSITIVE hysteresis is 2°C. The room temperature is 21°C and the set temperature is 22°C. The
product will remain on until the room temperature is exceeded by 2°C and therefore, when T>23.0°C
Example2: With the product off, NEGATIVE hysteresis is 2°C. The room temperature is 19°C and the set temperature is 20°C. The product will
remain off until the set temperature drops 2°C and therefore, when T<18.0°C
Factory settings: POSITIVE HYSTERESIS = 0
NEGATIVE HYSTERESIS = 2°
FORCED RESTART FROM START&STOP WITH BUTTON OR TEMPERATURE
As previously mentioned, when a shutdown occurs via START&STOP, the display indicates the off condition with the
icon, the key
remains green and the word STAND BY is displayed.
In this display condition, the product can be turned back on as follows:
1. Wait for the room temperature to drop below the intended temperature so that the
restart occurs via START&STOP
2. Deactivate the START&STOP with the relative
button
and proceed with a new start-up.
3. Change the intended temperature by pressing the
keys.
In this case, the temperature modification screen
appears. The equipment will turn on when the
setting is higher than the room tempe the
POSITIVE hysteresis.
On the other hand, it remains in STAND BY if the
setting is lower than the room tempe POSITIVE hysteresis and it is not possible to
switch on the device, even with the text .
