1 General
The Fan Coil ambient temperature controller with display is a continuous
KNX ambient temperature controller for fan convectors in 2 and 4-pipe
systems. It measures the current ambient temperature (actual value) and
sends a continuous manipulated variable (0 - 100%) to a fan coil actuator
to maintain the desired ambient temperature. The device operates in both
heating and cooling mode.
Hotel management systems can directly access the Fan Coil ambient
temperature controller with display via KNX and trigger controllers in the
room. The fan speed can also be selected manually with buttons (forced
operation). This makes it possible to adjust the hotel room temperature
as required by the customer or guest.
The device can be linked to the functions of the RM/S master room controller
and FCA/S fan coil actuator via the KNX.
This manual contains detailed information on the Fan Coil ambient
temperature controller with display, its installation and programming.
The operation of the device is explained using examples.
The manual is divided into the following sections:
Section 1 General
Section 2 Technology
Section 3 Commissioning
Section 4 Planning and Application
Section A Appendix

1.1 Overview of Product
and Functions
The Fan Coil ambient temperature controller with display records the current
room temperature and controls the heating and/or cooling. It also controls 2
and 4-pipe Fan Coil units and conventional air-conditioners.
The device is surface-mounted without a frame and is available in white
and aluminium-silver.
The display is backlighted for easier reading.
The device supports all functions for international hotel applications. It can
operate with the following operating modes: heating/cooling, heating only
and cooling only.
The ambient temperature controller is fitted with push-switches and an
LC display to show the current operating modes and values. The ambient
temperature controller is very easy and intuitive to operate with the use of
international symbols on the push-switches and in the display. The device
has five push-switches:
- ON/OFF, comfort/standby switch
- Temperature up
- Temperature down
- Fan stage adjustment
- Switch display of units °C/°F
The sensor is a surface-mounted device and does not require a cover frame.
A bus terminal is included for connection to the ABB i-bus®. A separate bus
coupling unit is not required. The Fan Coil ambient temperature controller
with display does not require an auxiliary power supply. The Engineering
Software Tool (ETS from version ETS°2°V1.3a) is used to assign the
physical address and set the parameters using a VD2 file, which is also
imported for use with ETS°3.

3 Commissioning
3.1 Application program
for the ambient
temperature controller
The Fan Coil Display Operate Control/1.2 application program for the Fan
Coil ambient temperature controller with display controls the device for
heating, cooling or heating and cooling. The ETS shows different parameters
and communication objects depending in the functions selected in the
"Control Function in Use" parameter.
A "2-point control", a "PWM control", a "Continuous control" or a "Fan Coil
Actuation" can be implemented for heating and/or cooling in all controller
functions. A supplementary stage for heating and also for cooling can also
be actuated.
A temperature value can also be received by an additional temperature
sensor via the KNX for improved temperature control in larger rooms.
The measured value is then applied to the ambient temperature control
with a defined weighting.
The ambient temperature controller can be operated with dependent or
individual setpoints. Dependent setpoints mean that the setpoints in standby
and night mode are always based on the basic setpoint, and with individual
setpoints a separate setpoint can be set for every operating mode.
(See also page 93 in Section 4.4 Setpoints at Planning and Application.)
The ambient temperature controller with display has summer compensation
to save energy and to maintain a reasonable temperature difference when
entering an air-conditioned building. A winter compensation function can
also be activated to maintain a pleasant temperature in rooms with large
areas of window during cold weather. (See also page 98 in Section
4.6 Compensation at Planning and Application.)

3.2 Parameters
3.2.1 Parameter window
"General"
Send "In operation" object
Options: - No
- Send value “0” cyclic
- Send value “1” cyclic
The "In operation" object reports to the bus that the device is operating
correctly. This periodic message can be monitored by an external device.
The following parameters are shown:
transmission period in s [1...65.535]
Options: - 1...60...65.535
The period at which the "In operation" object sends a message
periodically is set here.
Enable switchover of temperature display via button °C/°F
Options: - Yes, standard °C
- Yes, standard °F
- No, standard °C
- No, standard °F
This parameter enables the °C/°F push-switch. The user can then switch
the temperature display from °C to °F. The temperature is always converted
from °C to °F in the Fan Coil ambient temperature controller with display,
because only °C values can be sent to the KNX.
If the "No" setting has been made,the °C/°F push-switch has no function
and the user cannot change the display.

ABB i-bus£KNX Commissioning
© 2009 Busch-Jaeger Elektro GmbH – A Company of the ABB Group 14
Display during normal operation
Options: - No temperature display
-Absolute setpoint temperature
- Relative setpoint temperature (+/-K)
- Current setpoint
Use this parameter to specify what information is displayed in the
temperature sensor mode. The current temperature, the current setpoint,
the relative current setpoint (adjustable setpoint) or no temperature can
be displayed.
Display in adjusting mode
Options: - Absolute setpoint temperature
- Relative setpoint temperature (+/-K)
Use this parameter to specify what information is displayed in the
adjustment mode. The setpoint temperature or the relative current setpoint
(adjusted setpoint) can be displayed.
Display heat/cool is active
Options: - If operating mode is active
-When requesting heating or cooling
The heat/cool parameter shows the configuration either for "When
requesting heating or cooling" or "If operating mode is active". The initial
setting shows only heat or cool, if the system is actually heating or cooling.
Display illumination
Options: - Always On
- Always Off
- 5 seconds recovery time
Use this parameter to set the LCD backlighting. It can be on at all times,
off at all times, or it switches off automatically 5 s after an actuation.
Note:
If the 1-bit communication object "lighting" receives an On message,
the backlighting remains on until an Off message is received.
Operating mode switchover
Options: - 1 Bit (3 x DPT_Switch)
-1 Byte (2 x DPT_HVACmode)
Switching operating mode defines whether the ambient temperature
controller has three 1-bit communication objects, "Comfort/Standby",
"Night Mode" or "Freezing/Heat Protection", or two 1-byte communication
objects for switching operating mode.
If an ON message is received by the Comfort/Standby object in 1-bit
switching operating mode, the Comfort operating mode is activated.
If an OFF message is received Standby mode is activated.
If an ON message is received by the Night Mode object, night operating
mode is activated. An OFF message deactivates Night Mode.
Freezing/Heat Protection mode is also activated with an ON message
and deactivated with an OFF message.

ABB i-bus£KNX Commissioning
© 2009 Busch-Jaeger Elektro GmbH – A Company of the ABB Group 15
If an ON message is received by multiple objects, Freezing/Heat Protection
has a higher priority than Comfort Mode. Night reduction has a higher
priority than Comfort Mode.
When switching operating mode via 1 byte two 1-byte communication
objects are available.
Note: the two 1-byte communication objects have different behaviour when
receiving a message. One object evaluates received messages "normally".
This means, for example, if a comfort telegram is received, the room
thermostat switches to comfort mode. If a night telegram is received, the
ambient temperature controller switches to night mode. This object is
controlled, for example, by time switches.
The second object can "overwrite" the first object temporarily. This means,
for example, if a Freezing/Heat Protection telegram is received, the ambient
temperature controller switches to Freezing or Heat Protection mode.
If freezing or heat protection is reset by another message, the ambient
temperature controller activates the operating mode pending at the "normal"
object. As a result, it is capable of noting operating modes.
The following applies to the 1-byte communication object:
0 = Auto
1 = Comfort
2 = Standby
3 = Night
4 = Freezing/Heat Protection
5 – 255 = not allowed
Enable switchover of comfort/standby via button On/Off
Options: Yes
No
Use this parameter to enable switching between operating modes with the
ON/OFF switch. If "No", ... is set here, the push-switch is used for switching
the device on and off by pushing and holding (500 ms), if "Yes" is set, the
operating mode can be switched from Comfort to Standby and vice versa
by pushing and releasing the push-switch and the device is switched off by
pushing and holding it (> 500ms). If the device is switched off and switched
on with the ON/OFF push-switch, Comfort mode is set.

ABB i-bus£KNX Commissioning
© 2009 Busch-Jaeger Elektro GmbH – A Company of the ABB Group 16
Operation mode after reset
Options: - Comfort operation
- Standby
- Night mode
- Frost/heat protection
This parameter specifies the mode activated after resetting the temperature
sensor or after commissioning. Comfort mode is default, however Standby,
Night mode or Frost/heat Protection can also be selected.

Options: - -128
-…
-0
-…
- 127
Value range –128..127 corresponds to –12.8K..12.7K
If the actual temperature is recorded internally, it may be falsified by an
additional internal heat source, e.g. bus or network coupler. The falsified
value can be adjusted with the setting "calibration value for ambient
temperature measurement".
Setpoint larger when sending change
Options: - Inactive

- 0.3 K
- 0.4 K
- 0.5 K
- 0.6 K
- 0.7 K
- 0.8 K
- 0.9 K
- 1.0 K
If this parameter is set to a difference, the associated 2-byte communication
object "Current temperature" sends its current temperature whenever this
parameter changes.

ABB i-bus£KNX Commissioning
© 2009 Busch-Jaeger Elektro GmbH – A Company of the ABB Group 18
Send setpoint cyclic (0 – inactive, min)
Options: - 0 .. 60
If the current value is to be sent cyclically independent of a change,
the parameter "Send setpoint cyclic" must be set to a time. This may be
necessary, for instance, with a higher-level boiler that expects to receive
setpoints and current values within a certain time period. If values are not
received, a predefined supply line temperature is set that is no longer
oriented on actual demand.
Measurement of room temperature
Options: - Interior
- Exterior
- Interior and exterior
This parameter is used to set the measurement of the current temperature.
It can be measured "Interior," "Exterior" or "Interior and Exterior". Internal
measurement means that the temperature is taken directly from the room
thermostat. For external measurements, an additional temperature sensor is
used and is sent to the room thermostat via 2-byte communication object. If
you are measuring current temperature internally and externally, the room
thermostat determines the current temperature from the combination of
temperature values defined in the "Emphasis internal/external" parameter.
An additional sensor may need to be added for larger spaces.
Weighting interior / exterior
Options: - 10% / 90%
- 20 % / 80 %
- 30 % / 70 %
- 40 % / 60 %
- 50 % / 50 %
- 60 % / 40 %
- 70 % / 30 %
- 80 % / 20 %
- 90 % / 10 %
The "Weighting interior / exterior” specifies whether the internal temperature
sensor for the ambient temperature controller is included in the control.
If, for instance, the parameter is set to 60%, the current temperature is 60%
of the temperature measured internally and 40% of the value obtained
externally.
Monitoring temperature measurement
Options: - Yes
-No
The "Monitoring temperature measurement" parameter defines whether
the internal and, if connected, external temperature sensors are to be
monitored.

ABB i-bus£KNX Commissioning

In case of error the device output uses the specified value to run an
emergency function.
Monitoring time exterior temperature (0 – inactive, min)
Options: - 0 / 1 / … / 10 / ... / 60
If the "Monitoring temperature measurement" parameter is set to "yes",
the time within which the external temperature sensor must send a message
to the bus is set here.
Monitoring time exterior temperature (0 – inactive, min)
Options: - 0 / 1 / …/ 10 / … / 60
If the "Monitoring temperature measurement" parameter is set to "yes",
the time within which the outside temperature sensor must send a message
to the bus is set here.
Offset for ext. temp. meas.
(measured value changes by (-128..127)x0,1 K)
Options: - -128
-…
-0
-…
- 127
Value range –128..127 corresponds to –12.8K..12.7K
The measured outside temperature can be adjusted with this parameter.
This means that if the outside temperature is falsified by heat or cooling
effects at the temperature sensor, the measured value can be adjusted
up or down.
