The regulator is formed by circuits incorporating triac controlled by an external command, for the continuous motor speed variation from 40 up to 100% of 220V motor nominal speed, with 4 Ampere max nominal current. The regulator has been made specially for motors connected with fans, aspirators or pumps. It may also be used as a voltage variator for any ohmic load. See that the min. voltage regulation starts from 30-40% of line voltage. The regulator can change voltage from 0 up to max line voltage, upon request. It is housed in a plastic container: on the frontal panel are situated the switch, the hand grip command for speed variation, the trimmer for min. speed regulation and the 10 Ampere fuse, for regulator’s internal circuit protection.


For wall installation, fasten the regulator with 4 screws. RVM 4/E. Flush installation on standard boxes TICINO, GEWISS, … RVM 4/I.


We reccomend to follow carefully the instructions in order to avoid regulator or motor damage. Supply the regulator with regulation hand grip at min. (counter-clockwise turned). Motor supply: about 75V. With the trimmer on the frontal panel it is possible to regolate min. voltage from 75V up to 180V. Make sure that on min. voltage motor runs. If not, increase voltage using the trimmer. Turn the regulation hand grip clockwise: the motor speed will increase up to nominal speed. An internal trimmer (sealed) allows to reduce min. voltages under 75V. It’s reccomended not to touch it, as under 75V the motor could not run and therefore be damaged. In order to protect eletrically the regulator-motor unit, it’s necessary to install a suitable amperometer protection on the supply line.
