In this Section the KNX Communication Objects available for the NEEDO radiator are
described in detail.
This “one bit” communication object enables the radiator to be switched between OFF and
ON. It can also be used to unload the radiator from the supply network.
This communication object provides the information about the ON-OFF status of the
radiator.
TThis communication object allows the radiator to work with predened values of
temperature, differentiating the operative modes. The operative modes dened are listed as
follows:
0) Standard
1) Comfort (congurable, default 21°C)
2) Standby (congurable as offset, default -2K)
3) Night (congurable as offset, default -3K)
4) Antifreeze (congurable, default 7°C)
5) OFF
When the set point is driven by an external thermostat, the radiator enters in the Standard
operative mode. The chosen set point is then memorized and associated to this operative
mode.
Comfort value (in °C)
Standby offset value (in °C)
Night offset value (in °C)
Antifreeze value (in °C)
Default 21, min=15, max=25
Default= -2, min=-10,max=-0.5
Default= -3, min=-10, max=-2
Default= 7, min=5, max=12
This data point provides the information about the radiator status in terms of Operation
Modes. It returns the operation mode as integer from 0 to 5, according to what described for
the communication object 3).
This communication object allows the user to change the inner set point variable without
using a KNX thermostat. This communication object is 1 bit. The transmitted value increases
or decreases the setpoint with a default step of +/-0.5°C. In particular, if 0 is sent, then the
setpoint is decremented by a value of -0.5°C, and if 1 is sent the setpoint is incremented by
a value of 0.5 °C. The step size can be customized by using the associated parameter.
Setpoint modication step range (°C) Default=0.5, min=0, max=3
This communication object is the set point generally given by a KNX thermostat object, or
any other device that can transmit a temperature data information. It is expressed in Celsius
degree [°C]. This communication object modies the set point around which the radiator
controls the environment temperature.
This communication object returns the current set point set to the radiator. It is expressed in
Celsius degrees [°C].
It also provides a Send setpoint parameter that transmits the communication object value,
according one of the following criteria: on request, on change, cyclically.
Send Setpoint On change, On request, Cyclically
(default=0, min=0, max=240)
This communication object provides an interface with an external temperature sensor (e.g. a
thermostat, a temperature sensor,etc.). The internal regulation algorithm of the radiator will
control the environment temperature according to the value passed by this communication
object (as reference), and the setpoint. When this group object is activated, the reference
temperature variable sensed by the embedded radiator NTC, (that is commonly used by
the system control of the radiator, and is provided by the communication object nr. 13), is
ignored by the control algorithm. If for any reason the radiator stops receiving information
about the external sensor via the communication object 8, the control system will keep on
working basing its reference value on its embedded NTC sensor.
This communication object provides an interface with an external presence detector (or
presence sensor). The logic adopted by this eld is the following:
a) 1 Comfort
b) 0 Standby
This communication object provides an interface with an external window sensor. The logic
adopted by this eld is the following:
a) 1 Antifreeze
b) 0 Latest operation mode
This communication object noties any faulty relative to the embedded temperature sensor.
This communication object provides a notication when the load (heating element of the
radiator) is damaged.
This communication object gives the environment temperature estimated by the temperature
sensor (NTC) embedded on the radiator. Since the NTC is generally inuenced by
the surface radiator temperature, an internal algorithm compensates this error. This
communication object thus reports the actual estimated environment temperature. If
the radiator does not receive any information about the environment temperature by
