device is able to control the “slave” devices with time-scheduled programs, extending their functionality to that
of a chronothermostat (centrally controlled by the supervising device).
The communication objects indicated in the block diagram allows monitoring and modifying the current
conduction mode forced on the temperature controller. The object 35 –
Heating/cooling status out
is always
available, even when the thermostat function is set on heating or cooling only. When the function is set on
both
heating and cooling
, the cyclic sending on bus can be enabled; anyway, the information about the actual
conduction mode can be acquired with a reading request to this commiunication object.
The object 36 –
Heating/cooling status in
is exposed only when the function is both heating and cooling and
the switching among the different modes is performed by the bus.

Valve protection function
The function is suitable for heating and cooling systems that use water as thermal conveying fluid and are
provided with motorized valves for the interception of a zone or of a single room. Long periods of inactivity of
the system can lead to the blockage of valves: to prevent this, the room temperature controller may periodically
send a command to open / close the valve in the period of inactivity of the system. This possibility is made
available in the application program by means of the parameter "Valve protection function", further defined by
the frequency and duration of the valve control.
7.7.1.4
Remote Setpoint modification
The communication objects shown in Picture 9 allow to monitor the Setpoint forced modifications performed
locally by the user when interacting with the LCD display and the touch buttons of the room thermostat. The
communication objects (from now on: C.O.) also allow to perform the same modifications remotely, for example
from a supervisor software.
