1.2 INSTALLATION
To install the device, it is first necessary to mount the metallic plate into a square/round
standard appliance box through the suitable screws. Next, Flat Sensato is connected to
the KNX bus through the corresponding terminal on the rear side of the device, and
then the input terminal is as well connected to the rear of the device.
Once the input terminal and the KNX terminal are connected, the device can be easily
mounted on the metallic plate by the action of the fixing clips.
Finally, it is advisable to check that the device is properly installed, and that only its
profile becomes visible from above, from below and from both sides (the metallic plate
should be completely hidden).

This device does not need any external supply, as it is powered through the KNX bus.
The programming button (5) can be pressed with the help of a thin screw to set the
device into the Programming Mode. After a short press, the programming LED (4) will
light in red. Note that if this button is held while plugging the device into the KNX bus,
the device will enter the Safe Mode. The LED will then blink in red.
For detailed information about the technical features of the device, as well as on
security and installation procedures, please refer to the device Datasheet, bundled
within the original packaging of the device and also available at http://www.zennio.com.

2CONFIGURATION
After importing the corresponding database in ETS and adding the device into the
topology of the desired project, the configuration process begins by entering the
Parameters tab of the device.
2.1 GENERAL
From the “General” tab enabling additional functions available for the device is
possible.
ETS PARAMETERISATION
Figure 3 General settings
Inputs: enables or disables the “Inputs” tab in the tree on the left, depending
on whether the device will or will not be connected any external accessories.
See section 2.6 for details.
Logic Functions: enables or disables the “Logic Functions” tab in the tree on
the left, depending on whether this functionality is required or not. See section
2.7 for details.
Notification LED: enables or disables the “Notification LED” tab in the tree
on the left, depending on whether this functionality is required or not. See
section 2.5 for details.
Heartbeat (Periodical Alive Notification): this parameter lets the integrator
incorporate one-bit object to the project (“[Heartbeat]Object to Send ‘1’”)

that will be sent periodically with value “1” to notify that the device is still
working (still alive).
Figure 4. Heartbeat (Periodical Alive Notification)
Note: The first sending after download or bus failure takes place with a delay
of up to 255 seconds, to prevent bus overload. The following sendings match
the period set.

2.2 TEMPERATURE
Flat Sensato is capable of measure and monitor temperature measurements, as well
as send these values to the bus and report high / low temperature situations. To
that end, it is necessary to configure a set of parameters.
ETS PARAMETERISATION
The object “[Temp] Current Temperature” (2 bytes) will appear by default. This object
will report the current value of the temperature periodically or after a certain
increment/decrement, according to the parameter configuration.
Figure 5. Temperature - Configuration
Temperature Sensor Calibration: defines an offset to be applied to the
measurement received from the probe to correct deviations due to external
factors. The offset should be in the range [-50, 50] tenths of a degree.
Temperature Sending Period: sets every how much time the value of the
current temperature should be sent to the bus (through “[Temp] Current
Temperature”), in the range 0 – 255 tens of second. The value “0” leaves this
periodical sending disabled.
Send with a Temperature Change: defines a threshold (in the range 0 to
255 tenths of a degree) so that whenever a new reading of the current
temperature is found to differ (from the last value sent to the bus) more than
such threshold, an extra sending will take place. The value “0” leaves this
sending with a temperature change disabled.

Temperature Protection: drop-down list with the following options:
No: no temperature protection is required.
Overheating: overheating protection is required. Two extra parameters will
come up:
Overheating Temp.: maximum temperature permitted, in the range -30
to 125 ºC. Temperature readings greater than this will be considered
overheat, and therefore a “1” will be periodically sent through object
“[Temp] Overheat”. Once the overheat is over, a “0” will be sent (once).
Hysteresis: dead band or threshold (in the range 1 to 200 tenths of a
degree; the default is 20 tenths of a degree –i.e., twenty degrees–)
around the overheat temperature defined above. This dead band
prevents the device from sending the overheat alarm and no-alarm over
and over when the current temperature keeps fluctuating around the
overheat limit (T): once the overheat alarm has been triggered, the no-
alarm will not be sent until the current temperature is lower than that T
minus the hysteresis. After that, if the current temperature reaches T
again, the alarm will be re-sent.
Overcooling: overcooling protection is required. Two extra parameters
(analogous to the above two) will come up:
Overcooling Temp.: minimum temperature permitted, in the range -30
to 125 ºC. Temperature readings lower than this will be considered
overcool, and therefore a “1” will be periodically sent through object
“[Temp] Overcool”. After the overcool is over, a “0” will be sent (once).
Hysteresis: dead band or threshold (in the range 1 to 200 tenths of a
degree; the default is 20 tenths of a degree) around the overcooling
temperature. As for the overheat, once the alarm has been triggered, the
no-alarm will not be sent until the current temperature is greater than T
plus the hysteresis. After that, if the current temperature reaches T
again, the alarm will be re-sent.
Overheating and Overcooling: both overheating and overcooling protection
are required. The following three parameters will come up:

2.3 HUMIDITY
Flat Sensato is capable of measure and monitor humidity measurements, as well as
send these values to the bus and report high / low humidity situations. To that
end, it is necessary to configure a set of parameters.
ETS PARAMETERISATION
The object “[Hum] Current Humidity” (2 bytes), visible by default, will report the
current value of the humidity periodically or after a certain increment/decrement,
according to the parameter configuration.
Figure 6. Humidity - Configuration
Humidity Sensor Calibration: defines an offset to be applied to the
measurement received from the probe to correct deviations due to external
factors. The offset should be in the range [-12, 12] tenths of a degree.
Humidity Sending Period: sets every how much time the value of the
current humidity should be sent to the bus (through “[Hum] Current
Humidity”), in the range 0 – 255 tens of second. The value “0” leaves this
periodical sending disabled.
Send with a Humidity Change: defines a threshold (in the range 0 to 25 %)
so that whenever a new reading of the current humidity is found to differ (from
the last value sent to the bus) more than such threshold, an extra sending will
take place. The value “0” leaves this sending with a humidity change
disabled.
Flat Sensato

Humidity Protection: drop-down list with the following options:
No: no alarm is enabled.
Overheating: high humidity alarm is enabled. Two extra parameters will
come up:
High Humidity: Parameter to set the maximum humidity value from
which the alarm will be activated. This parameter is an integer value
between 0 and 100, referenced to % units. The default value of the high
humidity will be 65%. Humidity readings greater than this will cause that
“1” will be sent periodically through object “[Hum] High Humidity”. Once
the humidity is below, a “0” will be sent (once).
Hysteresis: dead band or threshold (in the range 1 to 25%; the default
value is 5%) around the high humidity defined above. This dead band
prevents the device from sending the alarm and no-alarm over and over
when the current humidity keeps fluctuating around the limit (H): once
the alarm has been triggered, the no-alarm will not be sent until the
current humidity is lower than that H minus the hysteresis. After that, if
the current humidity reaches H again, the alarm will be re-sent.
Low Humidity: low humidity alarm is enabled. Two extra parameters
(analogous to the above two) will come up:
Low Humidity: Parameter to set the minimum humidity value from
which the alarm will be activated. This parameter is an integer value
between 0 and 100, referenced to % units. The default value of the low
humidity will be 25%. Humidity readings lower than this will cause that
“1” will be sent periodically through object “[Hum] Low Humidity”. Once
the humidity is over, a “0” will be sent (once).
Hysteresis: dead band or threshold (in the range 1 to 25%; the default
value is 5%) around the low humidity. This dead band prevents the
device from sending the alarm and no-alarm over and over when the
current humidity keeps fluctuating around the limit (H): once the alarm
has been triggered, the no-alarm will not be sent until the current
Flat Sensato

humidity is greater than that H plus the hysteresis. After that, if the
current humidity reaches H again, the alarm will be re-sent.
Low Humidity and High Humidity: high humidity and low humidity alarms
are enabled. The following three parameters will come up:
High Humidity.
Low Humidity.
Hysteresis.
The three of them are analogous to those already explained separately.

2.4 DEW POINT
The dew point is the value at which the temperature of the air must decrease so that
the existing water vapour begins to condense.
The device is able to calculate the dew point and determine whether condensation on
the surface will occur, taking into account the measurements of temperature and
humidity. Please, refer to ANNEX I. Dew Point Theory for further information.
ETS PARAMETERISATION
Figure 7 Dew Point - Configuration
Dew Point sending period: sets every how much time the value of the
current dew point temperature should be sent to the bus (through “[Dew]
Dew Point Temperature”), in the range 0 – 255 tens of second. The value
“0” leaves this periodical sending disabled.
Send with a Dew Point Change: defines a threshold (in the range 0 to 255
tenths of a degree) so that whenever a new reading of the current dew point
is found to differ (from the last value sent to the bus) more than such
threshold, an extra sending will take place. The value “0” leaves this sending
with a dew point change disabled.
Condensation Protection: checkbox (disabled by default) to enable/disable
the condensation alarm.
Dew Point Offset: value that will be added to the theoretical dew point
temperature calculated by the system, whose result will be used as trigger

for the condensation alarm notification. Possible values from 0 to 255 (15
by default) tenths of a degree.
Hysteresis: dead band or threshold (in the range 1 to 200 tenths of a
degree; the default is 20 tenths of a degree) around the dew point. This
dead band prevents the device from sending the condensation alarm and
no-alarm over and over when it keeps fluctuating around the limit: once the
alarm has been triggered, the no-alarm will not be sent until the current
temperature is greater than that the dew point temperature plus the offset.
After that, if the current temperature reaches the limit again, the alarm will
be re-sent.

2.5 NOTIFICATION LED
2.5.1 CONFIGURATION
Flat Sensato has a LED to notify, through colours, the ranges of the current humidity
values. The colous to notify the humidity ranges can be two (green and yellow) or three
(green, yellow and red).
It is possible to modify by parameter the humitidy thresholds of the range
corresponding to each color. The following figure shows an example with the default
threshold values:
Figure 8. Default colors of Notification LED.
ETS PARAMETERISATION
After enabling “Notification LED” (see section 2.1), a new tab will be incorporated into
the tree on the left.
The parameters available in this tab are:
Colours Shown: allows selecting whether the notification LED comprises two
or three colours: “Green and Yellow” or “Green, Yellow and Red”(by default).
Red / Yellow / Green: humidity value (0-100%) from which the notification LED
will display the indicated colour. The limit values (0% and 100%) are not
editable. Default values are shown in the following figures.

2.7 LOGIC FUNCTIONS
This module makes it possible to perform numeric and binary operations with incoming
values received from the KNX bus, and to send the results through other
communication objects specifically enabled for this purpose.
Flat Sensato can implement up to 10 different and independent functions, each of
them entirely customisable and consisting in up to 4 consecutive operations each.
The execution of each function can depend on a configurable condition, which will be
evaluated every time the function is triggered through specific, parameterisable
communication objects. The result after executing the operations of the function can
also be evaluated according to certain conditions and afterwards sent (or not) to the
KNX bus, which can be done every time the function is executed, periodically or only
when the result differs from the last one.
Please refer to the “Logic Functions” user manual (available in the Flat Sensato
product section at the Zennio homepage, www.zennio.com) for detailed information
about the functionality and the configuration of the related parameters.
