EREF - THE PRACTICAL WITH BUILT-IN RECEIVER
The motors in this series are suitable for 40's, 60's as well as 70's 8-square shafts. This is possible due to the motors being available with a diameter of 35 mm and 45 mm. The EREF series has an integrated radio receiver and can be operated from heicko transmitters. The blocking recognition function of the EREF series reacts, if during the upwards movement, the rollers encounter a strong opposing force e.g. if they freeze on the window sill. The tubular motor is maintenance-free
with a high life span. Furthermore, the motor is also equipped with a thermal overload protection system as well as a silent motor.
