Fan Coil Unit Control
Fan Coil Unit Control
(OP)
I dont understand what does the automatic or manual change over thermostat mounted on the FCU ! What does he change over ? On winter on the innlet I have hot water and on the summer I have cold water !





RE: Fan Coil Unit Control
If this is your setup, then you need a summer/winter change over switch so that the FCU controller knows whether to open the valve as temperature rises (summer) or close the valve as temperature rises (winter).
