As unit 1 (setting 40), action of the respective user
interface can be assigned either to heating circuit 1 or
to both heating circuits. The second option is
necessary particularly when there are 2 heating
circuits and only one room unit.
Operation HC2
Depending on the setting of line 40, the operating
action (operating mode key or knob) can be defined
either on room unit 1, on the user interface or on the
operating unit for heating circuit 2.
•

The control for heating circuits 1 and 2 is shared.
•
Independently
Action of the control is called on the display whenever
use is made of the operating key or the knob.
Operation HCP
According to command line 40, the control action
(operating mode key or knob) can be defined either
on room unit 1, on the user interface, or on the
operating unit for heating circuit P.

The control for heating circuits 1 and 2 is shared.
•
Independently
Changes in the operating mode or adjustment of the
nominal temperature setpoint must be made in the
programming.
Readjustment room sensor
The room sensor indication can be corrected.
Software version
The indication shows the current version of the user
interface.
