Thank you for the information. As per the provided datasheets, we observe that there are 2 systems with different interfaces i.e. Tachikawa tacos 2 requires AC interface for the control whereas Hunter douglas requires dry contact interface. Hence I have 2 questions:
1) According to which system do we have to design our interface?
2) Except 37, 38 & 39th Floor, is there any other floor with curtain control requirement?
