3. 10. 5 Auto-reset of occupancy override
The TR80 can be configured to automatically cancel a user occupancy override when the
master occupancy mode changes (holding register 1500, refer
Occupancy control).
Bit definitions:
Bit0: When master mode changes to UNOCC, cancel UNOCC override
Bit1: When master mode changes to UNOCC, cancel STBY override
Bit2: When master mode changes to UNOCC, cancel OCC override
Bit3: reserved
Bit4 When master mode changes to OCC, cancel BYPASS override
Bit5: When master mode changes to OCC, cancel OCC override
By default, all bits are set
3.11 LIGHTING CONTROL
General lighting configuration parameters are as follows:
*In case direct DALI64 control on TR80 Modbus Port 2 this register is updated automati
cally In all other cases the Controller must write On – OFF status of group in this registers
to turn on the group on indication.
‘Group Light State’ bitmap register is used to represent which groups have at least on lamp
that is not totally off. This info typically comes from the DALI64MOD sensor.
If the DALI64 sensor is connected to port 2, the TR80 wall module will read the ‘Group
Light State’ directly, without any dependency on a master controller. If DALI64 sensor is
connected on port 1 (or a different lighting control system is employed) the master con-
troller will need to provide this information to the wall module.
The ‘Group Light State’ information (in combination with 'Group Level Feedback') register
is used for two purposes:
1.Light groups that are ON are indicated on the LCD with bulb symbols.
2.Where the power button functions to turn the lights on/off, the behaviour for the first
tap of the button is determined by the group light states and group level feedback.
