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 will show 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 dis-
play 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 neces-
sary 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

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 simul-
taneously pressing the
(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 se-
lected, the dead band for automatic switching on the air side will be brought
to 5°
LOGIC
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.
Min. 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 pro-
grammed setpoint (indicated on the display by the symbol 3). Should the
room temperature fall too far below this threshold, the logic will be temporarily
inhibited.
