Controllo Fancoil Con Piastra Radiante; Winter Operation; Summer Operation - AERMEC TX Serie Mode D'emploi

ELECTRIC HEATER (MANAGED AS INTEGRATION/REPLACEMENT)
In the case of fan coils requiring the use of the electric heater in combined replacement/integration mode, configure the thermostat as
shown below:
• Indicate the presence of the shut-off valve (2/3-way): dip 1 ON
• Indicate the presence of the water probe downstream: dip 2 ON
• Set 2T+2F control: dip 5 and dip 6 ON
Attention: even if the water probe is upstream of the valve, the season changeover is based on the air temperature.
With this configuration, the heater can have two different types of operation in heating mode, depending on how the thermostat works:
OPERATING MODE
AUTO
V1
V2
V3
AUX
PLASMACLUSTER AIR PURIFIER AND GERMICIDAL LAMP
If the accessory configured (via dip 5 and dip 6) is the air purifier (plasmacluster/bactericidal lamp), the "Aux" position is used to purify
the air regardless of the thermostat operation requests. This type of accessory is activated even if the operating speed selector is not
on "Aux". To run the purifying device at minimum speed regardless of the thermostat requests, use the "Aux" position; in this way,
the thermostat will always activate ventilation at the minimum speed, as shown in Table 3, closing the shut-off device that you are
advised to use alongside this function to avoid any deterioration of the environment (overheating or undercooling).
The plasmacluster device must be assembled on output Y2, in place of the second valve. Configure the thermostat to manage the
plasmacluster by setting dip 5 = OFF and dip 6 = ON. The plasmacluster is powered simultaneously with the ventilation function, in
both heating and cooling mode.
As described above, the plasmacluster device is used in the "Aux" position for purifying only, whereas in the other positions
(except OFF) it's activated on the basis of the thermostat operation requests. In the case of continuous ventilation (Dip 3 ON), the
plasmacluster remains active - along with ventilation - even when the thermostat request has been fulfilled.

CONTROLLO FANCOIL CON PIASTRA RADIANTE

SELECTION OF FANCOILS RADIANT CONTROL
To check the Radiant fan coils, the radiant plate adjustment must be selected by means of the dip 9 and dip 10 of the SW1 switch, the
functionality of these dips is described in the Dip-Switch Setting table.
OPERATING MODALITIES OF THE RADIANT FAN COILS
The TX/TXI thermostat can manage the Radiant fan coils as described in the figure:
Radiante

The electric heater intervenes if there is a thermostat operation request and the water temperature is sufficiently
low (as shown in the figure "Season changeover (water side) and Ventilation enabling")
The heater is activated as the sole heating source
