Honeywell TR80

41TR80 - Installation and Operation Guide
3. 8. 4 LCD Symbols
Most symbols on the LCD are activated with internal logic depending on current status (occu-
pancy etc). Other symbols can be only activated via Modbus by a master controller, as
explained below.
The alarm symbol is normally activated by internal fault conditions (see
Fault Conditions). The
master controller can override this as above.
3. 8. 5 Text override
If a non-zero value is written to this register, the upper screen area will display the selected
scrolling text. This overrides any other text that might otherwise be displayed.
