APPLICATION 

The fancoil room controller has been designed for individual control of temperature in commercial, industrial and residential buildings. It is tailored 

for two-pipe fan coils with two-wire electric valves and has 3 analogue outputs 0..10 V (EC fan, heating valve and cooling valve). A 6-way valve 

can also be used. In addition, an electrical heating coil can also be connected With its flush mounted modern design the device combines digital 

technology with a large LCD display and additional buttons, which enables the single room controller to be used intuitively.
