ELECTRONIC CONTROL FOR TERMINAL UNITS

II.3.3.5 HEAT
HEAT is the "heating" function. Even in this mode of operation, the
regulation that expresses the most comfort can be set as desired by:
 choice of the desired temperature value;
 fan operating mode with manual setting (*) or automatic speed
setting (AUTOFAN);
Depending on the setpoint set by the user, the activation of the hot
water valve is decided (see graphic below), while the fan is switched on
by means of the HOT START 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 hot 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 the case of a fan with EC-Brushless motor, the 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 of the set in manual mode (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.3.3.6 HEAT + RESISTANCE
The HEAT + ELECTRICAL RESISTANCE function provides for the
HEAT operating mode with automatic activation of the electrical
resistance (if declared present, see paragraph Dip-switch configuration)
based on the detected hot water temperature (Hot start function active
or not); then integrate or replace the hot water battery.
To avoid possible overheating, the fan is activated at the same time as
the resistor and remains active for a time equal to P12 (30s) after it has
been switched off. As a further protection, the resistance is deactivated
if the temperature of the battery exceeds the temperature of parameter
P09 (50 ° C).
Temp. Water <P03
Temp. Water> P09
P00 = Thermostat differential (0.2 ° C)
P03 = Hot Start Set Point (32 ° C)
P09 = Response threshold res. electric (50 ° C)
P11 = Set Point
Ta = Ambient temperature
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.
