-
weekly scheduler: 7 days, up to 6 events per day
-
another 5 variables (air quality, fan speed etc.)
–
each has a profile where max.
and min. values, step, number of decimals, and symbol set are defined.
It is also possible to set / reset any of the LCD symbols on the display over Modbus.
The turn / push knob has three basic functions:
•
instant edit (turning the knob)
–
settings of one predefined analogue value,
usually room temperature correction
•
quick edit (short push)
–
change of predefined state, e.g. Presence (Comfort /

brightness 0-100 % separately for knob and display. If user make some action with knob,
display and knob will shine for defined time. All of the backlight functions could be set
from Modbus master.
The unit Modbus address and functionality is defined over the RS485 interface with
service software
ModComTool
which is free for download at
int.com/en/downloads/software.
To interface the room unit to the computer use the
USB/485 converter
M080
, RS232/RS485 converter
R012
, or any suitable RS485 converter.
