KNX temperature control panel
1. USE
Combined with a KNX room temperature controller (with an embedded
temperature control algorithm), the KNX temperature control panel is
used to manage the heating/cooling control system (fan coil control
unit, heating/cooling valve, electrical load, etc) in the rooms where it is
installed, and can be configured for different applications as required.
The temperature control panel incorporates a user interface and a
temperature sensor.
This device is completely configurable in term of parameters, operating
modes and other features. Depending on the type of use, the backlit
display will show the following information: the current function or
mode (Heating, Cooling; Comfort, Eco, Frost/Overheat Protection), the
measured room temperature, the defined temperature setpoint, the
fan coil speed. It is a native KNX device and all the configurations and
associations must be made via ETS software (ETS versions 3, 4 and 5)
only.

7. OPERATING MODES
The control panel can operate in the following modes:
Comfort: customisable setpoint: ideal heating and
cooling temperatures (default 21°C)
Eco: energy-saving heating and cooling temperatures
Frost protection: minimum safe temperature
Overheat protection: maximum safe temperature
With a short press (3 seconds maximum) of the MODE key, the system
toggles between comfort, frost and overheat protection. Eco mode can
also be set from the system.
8. SYSTEM APPLICATIONS
The control panel can be set to manage three different applications,
depending on the type of system to be installed:
- Heating application (only heating is active)
- Cooling application (only cooling is active)
- Cooling and Heating application
8.1 Heating application
If the measured temperature is lower than the reference value, the
heating system is activated and the corresponding symbol appears
on the display. When the temperature is reached, the control panel
switches the zone off and the icon disappears.
Note: The heating icon is always displayed.
8.2 Cooling application
If the measured temperature is higher than the reference value, the
cooling system is activated and the corresponding symbol appears
on the display. When the temperature is reached, the control panel
switches the zone off and the icon disappears.
Note: The cooling icon is always displayed.
8.3 Heating and Cooling application
By configuring the control for both the heating and cooling functions,
it is possible to use it with the heating system in winter, and the cooling
system in summer. The icons shown on the display will be the same as
the ones previously described for the heating and cooling applications.
Depending on the measured temperature, the heating or cooling
system operating symbols (10 /11) will appear, to indicate that the
corresponding function is active.
If there are 2 tube fan coils, the changeover function can be used to
switch between the heating and cooling applications.
If there are 4 tube fan coils, the temperature control system can be
programmed for automatic operating mode. In this way, the (1/2) icons
are not displayed.

12.2 ETS parameters
List of parameters
The parameters are listed below:
Show on display:
With this parameter you can choose which information to show on the
display:
1 – Always setpoint
The monitor will always show the setpoint temperature, the
measured temperature will only be displayed during the calibration
procedure.
2 – Always measured temperature
The monitor will always show the measured temperature, the
setpoint temperature will only be displayed during the change
setpoint procedure.
3 – Allow display changing
The monitor will display both temperatures; you’ll be able
to change it by using object 30 or holding down the Mode
pushbutton.
Default display:
With this parameter you can choose which information to show by
default on the display.
This parameter is only active if the parameter“Show display” is “Allow
display changing”.
1 – Setpoint
2 – Measured temperature
Intensity mode normal:
With this parameter (1-100%) you can choose the maximum intensity of
the backlight.
This intensity will be the default backlight.
Use ECO/NORMAL mode:
With this parameter you can decide whether or not to use the ECO
display mode.
If YES, you can define the backlight ECO Intensity mode (0-100%).
You will then be able to switch between normal and eco display mode
by using object 31.
When the display is in ECO mode, it will automatically switch the
backlight to normal mode after a button is pressed; it will revert to ECO
after 30 s of inactivity.
12.COMMUNICATION OBJECTS CONTINUED
12.2 ETS parameters (continued)
Activate standby mode:
With this parameter you can decide whether or not to use the standby
display mode (monitor switch OFF).
If YES, you will then be able to switch between normal and standby
display mode by using object 32.
When the display is in standby mode, it will automatically switch the
backlight to normal mode after a button is pressed; it will revert to
standby after 30 s of inactivity.
Mode change:
Disable – a short press on the “mode pushbutton”will have no effect.
Enable – with a short press on the “mode pushbutton”you can switch
between COMFORT and PROTECTION modes.
Temperature sending:
Cyclical – the device will send the measured temperature on the bus
cyclically; the delay between two frames is configurable by a parameter.
Cyclic frequency – the parameter Changing step is not active.
On Change – the device will send the measured temperature on the
bus following a change of temperature, the step is configurable by a
parameter Changing step, the parameter Cyclic frequency is not active.
Cyclical + On Change – the device will send the measured temperature
on the bus cyclically (configurable by parameter Cyclic frequency) and
following a change (configurable by the parameter Changing step).
Offset temperature:
With this parameter (interval: 0.1°C, limits: -9.9°C +9.9°C) you can adjust
the temperature measured by the device depending on the installation
conditions.
You can even change this parameter locally with the calibration
procedure (long press on both + and – pushbuttons).

12.2 ETS parameters (continued)
Base Set Point temperature:
This parameter (interval: 0.1°C) represents the default setpoint
temperature of the system.
Every time the system mode switches between Comfort and ECO this
setpoint will be sent on the bus.
In this way Comfort mode will return to the default setpoint (even if
the customer had previously changed it) and ECO mode will always
have the same setpoint (“Base Setpoint – actuator delta” in the Heating
function or “Base Setpoint + actuator delta” in the Cooling function).
Number of tubes:
With this parameter you have to define whether the system is working
with 2 or 4 tubes, the choice must be the same as for the actuator
working with the thermostat.
2 tubes – the icons for the Heating/Cooling functions and Heating ON/
Cooling ON will depend on objects 13 and 14 as explained in the object
section. Objects 15 and 17 will be inactive (there is only one valve).
4 tubes – the icons for the Heating/Cooling functions and objects
13 and 14 will be inactive (there is no need for the Heating/Cooling
functions as the system is able to heat and cool at the same time).
Insensitive zone between heating/cooling:
Only for 4-tube installations (or 2-tube installations with automatic
changeover between Heating and Cooling) you MUST configure this
parameter with the same value as the corresponding parameter on the
actuator. In 2-tube installations without change between heating and
cooling the parameter is zero.
This is useful when the actuator is in cooling mode and sends back a
different setpoint on the bus (setpoint status = setpoint + insensitive
zone); in this case the display will show the setpoint sent instead of the
status.
Type of object for valve:
With this parameter you can choose the type of object (1 bit or 1 byte)
to communicate the status of the heating/cooling valve(s).
The choice must be the same as for the actuator.
1 bit – objects 15 – 16 are not active, objects 17-18 are active.
1 byte – objects 17 – 18 are not active, objects 15-16 are active.
Add Object ”HVAC mode”:
If yes, object 8 (HVAC mode) is active.
Add Object ”HVAC Status”:
If yes, object 7 (HVAC status report bit) is active.
To be used only with actuators using the same object.
Add temp. setpoint limit objects:
If yes, objects 5 and 6 (Temperature setpoint limit (high) and (low)) are
active.
If not, the setpoint limits are fixed (7°C and 35°C).
Use Fan functions:
If No, no other parameter, Fan object or Fan icon is available.
If Yes, you can use the Fan functions.
12.COMMUNICATION OBJECTS CONTINUED
12.2 ETS parameters (continued)
Fan Speed setpoint type:
With this parameter you can choose the type of object (1 bit or 1 byte)
to communicate the speed of the fan.
The choice must be the same as for the actuator.
1 bit – objects 19, 24, 25 and the “setpoint fan speed 1, 2, 3” parameters
are not active, objects 20, 21, 22, 26, 27, 28 are active.
1 byte – objects 20, 21, 22, 26, 27, 28 are not active, objects 19, 24, 25
are active.
Fan Speed setpoint 1:
Only if Fan Speed setpoint type = 1 Byte.
This is the fan speed value (%) sent on the bus (Object 24) by the control
panel when speed 1 is selected via Pushbutton.
It is also the highest limit (if Object 24 <= Fan speed setpoint 1) to
display the Fan speed 1 icon.
Fan Speed setpoint 2:
Only if Fan Speed setpoint type = 1 Byte.
This is the fan speed value (%) sent on the bus (Object 24) by the control
panel when speed 2 is selected via Pushbutton.
It is also the highest limit (if Fan speed setpoint 1 < Object 24 <= Fan
speed setpoint 2) to display the Fan speed 1 and 2 icons and the lowest
limit (if Fan speed setpoint 2 < Object) to display the Fan speed 1, 2 and
3 icons.
Fan Speed setpoint 3:
Only if Fan Speed setpoint type = 1 Byte.
This is the fan speed value (%) sent on the bus (Object 24) by the control
panel when speed 3 is selected via Pushbutton.
