ELECTRONIC CONTROL FOR TERMINAL UNITS
13
Fan and cold / hot water valve are operated as in cooling / heating.
When the set point is satisfied, the cold / hot water valve is closed and
the periodic ventilation function is activated (see dedicated paragraph).
If the room temperature is inside the hysteresis zones at the input in
AUTO mode (P11-P01) <Ta <(P11 + P01),
the working mode will be the last one that was always active in AUTO.
If there is no previous stored mode (for example, the first time the board
is powered) then priority is given to the heating mode.
IMPORTANT!
In the case of an EC motor, at each mode change
the fan is stopped for 90 seconds.
On the on-board control panel or on the wall, the
fan led flashes.
On the wall receiver the yellow LED and the red LED
flash.
II.3.3.2 COOL
COOL is the "cooling" function. In this operating mode, the regulation
that expresses the greatest comfort can be set as desired by:

choice of the desired temperature value;

fan operating mode with manual setting (*) or automatic speed
setting (AUTO);
Depending on the set point set, the activation of the cold water valve is
decided (see graphic below), while the fan is switched on, only on 2-
pipe systems, using the TOO COOL function (at the speed selected or
decided by the AUTOFAN function) .
When the room temperature (intended as the value of the control probe)
reaches the set point, the cold water valve is closed and the fan is
switched off.
P00 = Thermostat differential (0.2 °
C)
P11 = Set Point Legend:
V = valve status
Ta = room temperature
(*) in case of Yardy-I with EC-Brushless motor speeds are defined by
the following parameters:
P80 = Minimum speed value set manually (10%).
P81 = Average speed value set manually (60%)
P82 = Maximum speed value set manually (100%).
For the other units (Yardy-ID and Diva-I) refer to paragraph II.3.6 "Dip-
switches configuration".
IMPORTANT!
In the case of an EC motor, at each mode change
the fan is stopped for 90 seconds.
On the on-board control panel or on the wall, the
fan led flashes.
On the wall receiver the yellow LED and the red LED
flash.
II.3.3.3 FAN
FAN is the "ventilation" function. In this operating mode, the fan speed
can be set as desired (min-med-max-AUTO). Note: if set to AUTO, the
speed is the average.
If the FAN mode is selected in models without a valve with circulating
hot (or cold) water, the unit can heat (or cool).
In this mode the display shows FAn.
II.3.3.4 AUTOFAN
The AUTOFAN function establishes the fan speed if there is no manual
setting. In cooling and heating mode the speed is higher the greater the
deviation of the room temperature from the set point.
P00 = Thermostat differential (0.2 °
C)
P11 = Set Point
P16 = Speed step (1 ° C)
Legend:
1 = heating (winter)
2 = cooling (summer)
Ta = room temperature
Vv = fan speed
In the case of a brushless motor, the AUTOFAN regulation is as follows:
P00 = Thermostat differential (0.2 °
C)
P11 = Set Point
P16 = Speed step (1 ° C)
P80 * = Minimum speed value set
in manual mode (10%).
P82 * = Maximum speed value set
manually (100%).
Legend:
Vv = Fan speed
Ta = Ambient temperature
* for Yardy-I. For the other units (Yardy-ID and Diva-I) refer to
paragraph II.3.6 "Dip-switches configuration".
