3.16 DISPLAY VALUES

In addition to the operationally required ones, TR80 can display several additional values
for user information. The master makes these values available to the wall module by writ-
ing to relevant registers.
For these registers, the default value is 32767 (hex 7FFF) representing an invalid value.
Any of these registers with the invalid value will be ignored by the wall module. As soon as a
valid value is received from the master controller, it will be available for viewing by the user.
However, if no updates are received for a configurable timeout period, a value will be con-
sidered stale and no longer displayed.

3. 16. 1 Room Temperature and Humidity Override

Firstly, override registers are provided in case the master controller needs to display
another measurement instead of the on-board sensors.
