37 TR80 - Installation and Operation Guide
An override cancellation occurs when a bit is set (on a change from 0 to 1). The wall module
takes no action when a bit is cleared.
3. 4. 3 What has changed
This register changes when the user makes any adjustment on the wall module. It can be uti-
lized by a master controller to reduce comms. It will be sufficient for the controller to read only
this register until a non-zero value is received. Then, and only then, the controller would need
to read the new user setting from the relevant register.
It is important to note that this register automatically returns to the default value of 0 as soon
as it is read by the master controller. There is no need for the master to reset it.
3. 4. 4 Active Display Mode
This register allows monitoring of the current user mode.
