Single-phase thyristor for variable fan speed
control and for switching off and on. Designed for
surface mounting. Fits in rectangular mounting
case. The regulator controls a maximum of 2-3
units. Max input 5A. 2221AG regulates units
without heat (AD310A, AD315A, AD320A, AD410A,

FRE6, Digital variable fan speed regulator
FRE6 has two different regulations to control the
air curtain. The UT-regulation that is controlled by
the door contact, room thermostat and the outdoor
temperature- and the IT-regulation that is
controlled by the door operation. Regulates a
maximum of 1-3 units. Max input 6A. With a
supply current above 6A a slave unit must be used.
It regulates electrically heated units . Protection
class: jet-proof (IP54)
