page when setting
: in each case
In this page it is possible to enable the reading of a
KNX probe that sends the measurement data to the
thermostat through the communication object:
<Temperature> KNX Probe Temperature
This object is to receive values of temperature from other
devices
Survellaince time for KNX
probe (0=disabled) [min]
Whenever the thermostat receives valid data
from the KNX probe, it considers this value in
calculating the measured temperature and
resets the internal timeout (monitoring time).
If the KNX probe is enabled, the monitoring
time is used to check whether the additional
temperature sensor periodically sends valid data to
the thermostat. This mechanism avoids considering
valid some data that can be hours or days old as
would happen if, for example, the additional sensor
does not work or the thermostat cannot receive
data for a long period of time.
A value for the additional sensor
surveillance time must be set which is more
than double the period set for the cyclical sending
of the additional sensor.
17. Thermostat
The temperature function can be configured as a
thermostat to control the temperature of a room or
area by driving heating or cooling equipment / air
conditioning fan coils / valves or through
commands on / off to heating /cooling elements
such as radiators, heat pumps, split, etc. ..
Thermostat operates temperature in a
range from -9.9 ° C to + 99.9 ° C with 0.1°C
resolution. Setpoint values (including SETPOINT
MODE) from the bus are accepted in a range from
10°C to 50°C
Setpoint Settings
The control setpoint can be changed by bus in two
different ways, via one of these objects:
HVAC Mode
SETPOINT Mode
The right policy to adopt depend from the device
that acts as a master, a time thermostat, a control
panel or a SW supervisor. Here the list of object for
changing the active mode or setpoint value by bus.
SETPOINT Object
When "Thermostat control mode" parameter is
selected with the value SETPOINT MODE, object
HVAC Mode is no longer visible.
Each time the thermostat receives a value on object
SETPOINT MODE ( 2 byte size), it is used as setpoint
for temperature control.
HVAC MODE obj. (switched heat / cool)
Using the HVAC MODE object (size 1 byte), it is
possible to set the thermostat in one of the
following modes: OFF; ECONOMY; STANDBY;
COMFORT; each mode is associated with a setpoint
set by an ETS parameter.
OFF mode is associated with the antifreeze setpoint
in heating mode and at the high temperature
protection set point in cooling mode.
