6 - CONTROL
After about 20 seconds from the last action, the panel's
brightness is suitably reduced to increase comfort during the
night and the ambient temperature is shown on the display.
Maximum brightness is restored by pressing any key.
ON / Standby
The control makes the control of the ambient temperature fully
autonomous by setting the setpoint that can be adjusted from
5 to 40°C, one of the 4 speeds and the summer/winter
selection.
As it is connected to the water temperature probe inside the
coil, it performs the minimum winter function (30°C) and
maximum summer function (20°C
).

Heating/Cooling: allows to switch the operating
mode between heating and cooling (2 seconds).
Allows to activate the appliance, to select one of
the 4 speeds or put it in stand-by (2 seconds).
Press the ON / Standby
Select one of the 4 operating speeds by pressing the relative
key AUTO
Stand-by: keep the ON / Standby button pressed for about 2
seconds. The lack of a warning light indicates the "stand-by"
status (no function).
When the control is set to this operating mode it guarantees
an anti-freeze security.
If the room temperature falls below 5°C solenoid valves are
activated.
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.
