KNX offers a control solution for every type of curtain and blind motor however as the amount of control can vary it is important to understand the difference so you can guarantee the end result.Ģ30V motors have a phase (live) for each direction of travel along with a common (neutral). This is a good option if the fitting is likely to be changed by the customer or if slightly more accurate positional control is required. Some control actuators also use current detection to determine when the fitting has reached its limit. This is achieved by defining the run time of the fitting in the parameters of the actuator via ETS. This can be relied on to stop movement however the KNX actuator will still need switch off a short time after. Most curtain and blind motors will have an integrated limit switch which stops movement when the limit of travel is reached. KNX actuators are referred to as blind actuators however they can also be used for all types of shading and window control including curtains, louvers, window motors, venetian and roller blinds Automating blinds and curtains offers a range of benefits from making the building more comfortable to reducing energy and even time saving. ![]()
