NOTE
If a fan-coil is used in heating systems the fan must
not turn when the water is cold, to avoid cooling
the room instead of heating it. Some fan-coils
have a water temperature sensor to perform this
function. If a fan-coil without sensor is used an
efficient solution is that of using an immersion
thermostat to be installed on the water return pipe.
The thermostat contact commands a remote switch
to which the fan-coil power supplies are connected.
