> Post-ventilation due to switching off of the heating element: this function will be
maintained until the set time has elapsed, even if the operating mode is changed.
During post-ventilation the water temperature enabling signal will coincide with
the one seen for fan operation.

HEATING ELEMENT
The electrical heating element is a device used to provide support where necessary
in the heating mode. (SW water sensor compulsory)
Selection
If provided for in the configuration, the heating element can be selected in the heating
mode by pressing the Sel
Activation
If use of the heating element is selected by the user, it will be activated on a call from
the thermostat based on the room temperature
NB: switching it on will force the fan on as well
Water control
Enabling of the heating element is tied to the water temperature. The related enabling
logic is described below
The enabling signal will not be given if the water sensor is either not present or
disconnected
DISPLAY
The display shows the following information

ECONOMY
The Economy function corrects the setpoint by 2.5°C and forces the fan to run at the
minimum available speed to reduce unit operation.
- Cooling: setpoint + 2.5°C
- Heating: setpoint - 2.5°C
ACTIVATION
This function can be activated by pressing the key
DISPLAY
The Economy function is shown on the display by the symbol

MINIMUM TEMPERATURE CONTROL
This logic makes it possible to keep the room temperature from falling too far when
the thermostat is off by forcing the unit into the heating mode if necessary and for
the time required.
If the heating element is present, it will be used only if it was previously selected as a
resource in the heating mode.
Selection
When the thermostat is off, you can select the minimum temperature control by pressing
at the same time the keys
The same key combination disables this function.
ACTIVATION
If this control is selected, the unit will switch on when the room temperature falls
below 9°C.
When temperature exceeds 10°C the thermostat will resume the Off status.
NB: Any Off command from digital input will disable this logic
DISPLAY
The display shows the following information
> Minimum temperature control selected: symbol

> Minimum temperature control enabled: Defr indication
DEHUMIDIFICATION
The dehumidification function, enabled only in the Cooling mode, activates operation
of the indoor unit in order to achieve a 10% reduction in the level of humidity present
in the room at the time the function itself was selected.
Selection
Dehumidification can be selected/unselected in the Cooling mode by simultaneously
pressing the buttons.
In the absence of a water probe (P04=0), or of a remote humidity probe in cases where
the controller is installed directly on the unit (P08=0), selection will not be enabled. If
selected, the dead band for automatic switching on the air side will be brought to 5°
Once selected, the dehumidification logic sets the target humidity level as the humidity
present at the time the function was selected minus 10%. Where the room humidity is
less than 40% the target level will be set at 30%.
The fan will be forced to run at low speed or, if the temperature is much higher than
the setpoint, at medium speed.
In order to bring the humidity to the set value, the fan (and valve, if present) will be
activated even if the room temperature has already reached the programmed setpoint
(indicated on the display). Should the room temperature fall too far below this threshold,
the logic will be temporarily inhibited.
