Speed V1 is activated when the temperature value is lower than the “setpoint -
valve
-
1heat
” value (in heating mode) or higher than the “se
valve
+
1cond
” value
(in cooling mode), and deactivated when the temperature value reaches the “setpoint -
valve
” value (in heating mode) or the “se
valve
” value (in cooling mode). The
first speed is also deactivated when a higher speed needs to be activated.
Speed V2 is activated when the temperature value is lower than the “setpoint -
valve
-
1heat
-
2heat
” value (in heating mode) or higher than the “setpoint +
valve
+
1cond
+
2cond
” value (in cooling mode), and deactivated when the temperature value
reaches the “setpoint -
valve
-
1heat
” value (in heating mode) or the “setpoint +
valve
+
1cond
” value (in cooling mode). The second speed is also deactivated when a
higher speed needs to be activated.
Speed V3 is activated when the temperature value is lower than the “setpoint -
valve
-
1heat
-
2heat
-
3heat
” value (in heating mode) or higher than the “se
valve
+
1cond
+
2cond
+
3cond
” value (in cooling mode), and deactivated when the
temperature value reaches the “setpoint -
valve
-
1heat
-
2heat
” value (in heating
mode) or the “se
valve
+
1cond
+
2cond
” value (in cooling mode).
With regards the heating (cooling) solenoid valve, you can see that once the detected
temperature is lower (higher) than the “setpoint -
valve
” (“se
valve
”) value, the
thermostat sends the activation command to the solenoid valve that manages the heating
system; the solenoid valve is deactivated when the detected temperature reaches the fixed
setpoint value. In this way, the heating (cooling) of the fan coil can also be exploited for
irradiation, without any speed being activated.
To avoid continuous switchovers, the thermostat can wait up to 2 minutes before sending
the activation command to the actuator that controls the temperature adjustment system, or
to the actuator channels that command the fan coil speeds.
