Hvac Mode Selection - Honeywell TR80UWD Installation And Operating Manual

3. 9. 3 HVAC mode selection

TR80 allows two different Hvac mode selection options: simple or advanced. In simple
mode, the occupancy button simply and directly switches between available modes (heat-
ing/cooling/fan-only...) similarly to a basic A/C unit.
Applications that have more complicated requirements (for example having two different
cooling systems within the same room) can use the advanced mode.

Register 1201 allows a master controller to control the LED ring to indicate the status of
cooling and heating in the room. A constant blue means that cooling mode is active, but is
not currently switched on. A constant orange means that the heating mode is active, but is
not currently switched on. The ring begins to breathe as soon as the room is cooled or
heated. A breathing green means the fan is on with no cooling and no heating. Gray means
that no cooling and no heating is currently possible; the central cooling and heating sys-
tem is turned off or the room user has disabled cooling or heating via a HVAC Mode over-
write.
Register 1201 is encoded as follows:
• Bit representation: 000D CCBB 0000 0AAA
