Minimum Temperature Control - Daikin FWEC3 Installations- Und Bedienungsanleitung

WATER CONTROL
Enabling of the electrical heater 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
IThe display shows the following information
■ electrical heater selected by the user:

■ active electrical heater :
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 electrical heater 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.
N.B.: Any Off command from digital input will disable this

DEHUMIDIFICATION
The dehumidifi cation 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
Dehumidifi cation can be selected/unselected in the Cooling
mode by simultaneously pressing the
If the water probe (P04=0) or the remote humidity probe is not
available, in cases where the controller
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 dehumidifi cation logic sets the target hu-
midity 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
