change icon based on another object

[khalil]

Hello,
I have this case:
Fan will be controlled by object (fan control)
Fan status based on Contactor (binary input)
IF the overload is tripped the contactor still operate leads to unreal feedback.
I want to change the fan icon to stop instead of run if the overload tripped 

previously solved by tags and resident or event based scrip, but I am looking for more efficient way especially when having lot of these.
Could this case be solved by JS
