Note
If a fan-coil is used in a heating system, it should be
ensured that the fan does not operate when the water
is cold, to avoid cooling the room rather than heating it.
Some fan-coils are tted with a water temperature probe
for this function. If a fan-coil without tted sensor is used,
an eective solution is to install an immersion thermostat
on the water return pipe. The contact of the thermostat
controls a remote switch, to which the fan-coil power
supplies are connected.
