MECHANICAL REGULATOR FOR FAN-COIL

FAN TA3

FAN TA3 SE is an electromechanical steam expansion re-

gulator for fan-coils, radiators and fan convectors. It is

ideal for regulating home or office temperature in its two

modes of operation: Summer/Winter (to activate the air

conditioning or heating functions). It is also equipped with

a mechanical three-position switch for regulating fan spe-

eds and to control the hot/cold valve.
