Hi there, I am developing a Piced Screen and want to create a single page to control the zones in set of thermostats. I can see the SetCompStringProp allows me to change component values at run time. And I can see the built in "System IO Number" tag that can change the System IO. However I cannot see a built in string to set the Zone Group and Zone Bit Mask. Please can we have a function to do this? Also - any prospect of enabling these on the B&W Mk II screen? THanks Mark
