can be manually operated by crank handle but the modern way is via an integrated remotely controlled motor.
Solar Control is, where the device operates automatically when a certain degree of light is received by the sensor. This is especially useful where sunblinds are specified to prevent furnishings or stock fading as the blind will operate even when no one is present.
An anemometer (wind speed sensor) is always fitted when timer or sun sensors are used in order that the blind is retracted in windy conditions that otherwise could result in damage.
Deans can design command controls to operate combinations of units to operate together, or in groups and can de-activate other control units, such as timers or other sensors according to a customer's requirements.
