Abstract
A method of controlling tint for a plurality of electrochromic devices, performed by a control system, is provided. The method includes receiving a request to change tint level of a plurality of electrochromic devices, and consulting transfer functions for tint level relative to drive for each of the plurality of electrochromic devices, wherein at least one of the plurality of electrochromic devices has a transfer function differing from at least one other of the plurality of electrochromic devices. The method includes driving each of the plurality of electrochromic devices in accordance with the transfer functions, so as to coordinate tint level or rate of change of tint level across the plurality of electrochromic devices.
