With regards the heating (cooling) solenoid valve, you can see that once the detected
temperature is lower (higher) than the "setpoint -
thermostat sends the activation command to the solenoid valve that manages the heating
(cooling) 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.
Both figures refer to the three-stage control of the fan coil, as the descriptions are complete.
For two-stage or single-stage control, the logic is the same, but not all the speeds are
controlled.
