Abstract

An adjustment mechanism is coupled to a regulating motor with a circuit provided incorporating a light ingress monitor and a number of operational amplifiers. One of these is connected to amplify a signal from the monitor, and the other is connected as a comparator. Two of the amplifiers are connected as drive circuits for the motor. A toggle circuit is connected between the comparison circuit and a further light monitor for night reduction of the adjustment circuit, so that the slats (13) are adjusted to a closed position at the time. A changeover switch is fitted between each of the drive circuits and the motor for manual operation of the latter, with a potentiometer fitted between the drive circuits to produce the desired signal variation before the motor is activated.
