–
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 multifunction button set has three basic functions:
•
instant edit (left / right button)
–
settings of one predefined analogue value,
usually room temperature correction
•
sunblind up / down (up / down button)
–
control of two digital outputs with
sunblind control functionality (slat angle, up / down, move to end positions)
•
quick edit (short push of the central button)
–
change of predefined state, e.g.
Presence (Comfort / Standby / Off), Air condition (Auto / Heating / Cooling /
Fan only / Off) etc.
•
long push of the central button
–
jump to menu where values are listed by left
/ right buttons, short push selects the value to be edited, and the value is
changed by left / right buttons followed by short push for confirmation.
After definable inactivity time, the display goes back to its basic state with rolling

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
R012
, or any suitable RS485
converter.
