night functioning
Keep the night functioning button.
When the function is activated, the relative symbol on the
display turns on.
Selecting this operating mode, the ventilation speed is limited
to a much lower value and the set temperature is
automatically adjusted as follows:
- reduced by 1° C after one hour and a further degree after 2
hours in the heating function.
- Increased by1°C after one hour and a further degree after 2
hours in the cooling function.
minimum ventilation speed
Keep the minimum ventilation speed button.
When the function is activated, the relative symbol on the
display turns on.
The ventilation speed is limited to a lower value.
heating / cooling
Press and hold the Heating / Cooling key for about 2 seconds
to switch the operating mode between heating and cooling.
This is reported by the fact that the 2 symbols, active heating
or active cooling, turn on.
In heating mode, the symbol is ON with setpoint higher than
the room temperature, both OFF with lower setpoint.
In cooling mode, the symbol is ON with setpoint lower than the
room temperature, both OFF higher with setpoint.
In the versions with 4 pipes, with the automatic heating/
cooling adjustment on, if the 2 symbols turn on
simultaneously, this means that the setpoint has been
reached (neutral band).
If one of the 2 symbols is flashing, this means that the (hot or
cold) water temperature has not been reached and the fan
stops until the temperature reaches a value that is suitable to
meet the request.
If the water temperature does not reach a suitable value in
relation to the required operating mode, after 10 minutes the
control is blocked and the symbol indicating the E5 alarm
appears.
This is automatically unlocked after 45 minutes or manually by
pressing one of the 8 keys.
6 - CONTROL
maximum ventilation speed
Keep the maximum ventilation speed button.
When the function is activated, the relative symbol on the
display turns on.
With this operating mode, maximum power is obtained
immediately both in heating and cooling.
Once the desired ambient temperature has been reached, we
recommend selecting one of the other 3 operating modes to
achieve greater thermal and acoustic comfort.
By pressing the ON stand-by and Temperature keys together
for 1 second, this activates the local block of all the keys.
This is confirmed by the fact that the word Loc. is displayed.
The user is prevented from using all the adjustments and
pressing any key and the display shows Loc. The keys are
unlocked by repeating the sequence.
alarms
E2 +
Failure affecting the water temperature probe of the versions
with 2 pipes (H2) located in the main coil.
E3 +
Failure affecting the cold water temperature probe of the
versions with 4 pipes (H4).
E4 +
Problem affecting the fan motor (for instance a jam due to
foreign bodies, a rotation sensor failure, activation of the
protective micro switch due to the fact that the filter is being
cleaned).
E5 +
If after 10 minutes of operation, the water temperature has not
reached a value suitable in relation to the required operating
mode, the contact of the solenoid valve and the enabling input
to the chiller or the boiler is disabled (Example 1: in heating
mode with an ambient temperature of 20°C and water
temperature below 15°C. Example 2: in cooling mode with an
ambient temperature of 20°C and water temperature above
25°C).
This is automatically unlocked after 45 minutes or manually by
pressing one of the 8 keys.
