–
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 /
Standby / Off), Air condition (Auto / Heating / Cooling / Fan only / Off) etc.
•
long push
–
jump to menu where values are listed by turning the knob, short
push selects the value to be edited, and the value is changed by turning the
knob followed by short push for confirmation.
After definable inactivity time, the display goes back to its basic state with rolling
display of selected values (e.g. actual temperature and CO
2
).
The unit Modbus address and functionality is defined over the RS485 interface with
service software
ModComTool
which is free for download at
. To interface the room unit to the computer use the
USB/485 converter
M080
, RS232/RS485 converter
M011
, or any suitable RS485
converter.
