for any different purposes.
The LCD on the front side displays information about temperature,
setpoint, fan coil speeds and operative status.
The control elements available on the front are four push buttons

3. Product and functional overview
The Inwall Room Thermostat TM11A01KNX/TM11A11KNX is an EIB/KNX wall mounting
device designed for HVAC applications in Home and Building installations (i.e. offices,
hospitals, hotels, private houses, etc..).
The device is equipped with one binary input (potential free contact) that can be used, for
instance, to control the HVAC units whether a window has been opened (or closed) or for
any other general purpose usage and one binary output relay to control fan coils or for any
different purposes.
The temperature control is managed with an On/Off, Proportional, Integrative or PI
algorithm and can be configured to control the following applications:
Heating and Cooling with two tubes common to both fluids (Warm and Cold).
Four circuits for heating and cooling
1, 2 or 3 fancoil speed in ON/OFF regulation
Proportioned motorized valves regulation (continuous control).
In addition to the temperature regulation described, the thermostat allows the following
operating modes:
User inside the room (Comfort mode). The regulation follows the set point that is
fixed from the control/supervision center or modified by the client.
User outside the room (Standby mode). The regulation follows the set point fixed
from the control/supervision center for this mode.
Night Application (Economy Mode). The regulation follows the set point fixed from
the control/supervision center for this mode.
Antifreeze (frost protection).
The user, using dedicated push buttons placed in front of the thermostat, can modify the
temperature setpoint and fancoil speeds.
In case user changes the fancoil speed via a front push button the thermostat pass from
automatic to manual functioning. The automatic functioning mode is restored when the
functioning scheme changes (Comfort, Standby or Economy).
In the thermostat the following parameters can be configured:
Room Temperature Set Point (from 5,0 to 45.0°C or °F correspondent value). The
set point is normally fixed from the control/supervision centre. The client can vary
the set point trough dedicated buttons. The variation can be executed in between
limits fixed from the control/supervision centre (minimum and maximum).
Fan Coil Speed (OFF,1, 2, 3). The fan coil speed is normally managed automatically
from the thermostat. If the clients modify the speed set, the thermostat is forced in
manual mode. The fan coil will get off when the temperature is reached.
Comfort temperature set point (one for cooling and one for heating). This parameter
is set from the control/supervision centre and used when the client is in the room.
Stand by Temperature Set Point (one for cooling and one for heating). This
parameter is set from the control/supervision centre and used when the client is not
in the room.
Economy Set Point (one for cooling and one for heating). This parameter is set from
the control/supervision centre and used when the room is not assigned or by night
to generate an energy saving.
System Type: Two Tubes ON/OFF (only heating, only cooling or both), Four Tubes
ON/OFF (heating and cooling with independent lines), Two Tubes with proportional
command, Four Tubes with proportional command. The parameter is fixed while
installing or testing the system, using ETS SW.
Valves Type: ON/OFF Valves, or Motorized. The parameter is fixed while installing
or testing the system, using ETS SW.

Commutation Range between Heating and Cooling. Heating or Cooling action can
be forced from the control/supervision centre and at each season change.
On the display the following information are visualized (see Fig. 1):
Setpoint. The value is displayed in the LCD with XX.X°C format (or in the
correspondent °F value to be selected while installing the system). Using the Set
point variation buttons, the temperature is varied in a range fixed with ETS. Pushing
continuously a button, the value will initially vary of 0,1°C and will proportionally
accelerate the variation speed.
Actual Temperature. In the LCD is displayed the real or actual temperature, in
XX.X°C Format (or in the correspondent °F value to be selected while installing the
system).
Fan Coil Speed Visualisation. The value, from speed 1 to speed 3, is indicated by a
specific icon on the display. This indication is visualised if the system is configured
for fancoil usage.
Some icons concerning actual operative status.
Fig. 1: Display and icons
The thermostat transmits to the KNX/EIB bus the following information:
Real Setpoint Value (also cyclically sent with time period setting)
Real Temperature (also cyclically sent with time period setting)
Objects for actuator command (Fan coil and Valves)
Power failure (and restore) alarm, if enabled.
This device provides also an alarm function by sending an “Alarm” object (1bit) to alarm, for
instance, a centralized visualization software that a power failure has been occurred and
then recovered next (this object is sent as the power supply is recovered).
The physical address, group address and parameters are assigned and programmed with
the ETS tool software. In order to commission the device, a PC with ETS2 version V1.3 or
higher is required as well as an interface to the bus, e.g. via an RS232 interface or via a
USB interface.
