General Description
The TCY-FT-U is a stand-alone electronic universal controller with one temperature control loop.It may use
up to 2 PI sequences. The TCY-FT-U features 1 internal NTC temperature sensor, up to two external
sensors inputs and up to four binary outputs.The configuration hasbeen reduced to aminimum to allowfor
a simple and off the shelve usage. For more advanced features and current in- and outputs the TCI product
range is recommended. The TCY-FT-U can be configured using the standard operation terminal. No special
tool or software is required.

Selection of actuators and sensors
Use only our approved NTC sensors to achieve maximum accuracy. Recommended is SDB-Tn10-20 as
Duct sensor, SRA-Tn10 as Room sensor and SDB-Tn10-20 with AMI-S10 as immersion sensor.
3-point Actuators:
Actuators with constant running time are recommended. Observe power limits. Do not use actuators with
power consumption > 6VA. Adjust running time in SW. Default running time is 90s for fully open / close
running time.
Mounting location
On an easy accessible interior wall, approx. 1.5 m (4.5’) above the floor in an area of
average temperature.
Avoid exposure to direct sunlight or other heat sources, e.g. the area above radiatorsand
heat emitting electrical equipment.
Avoid locations behind doors, outside walls and below or above air discharge grills and
diffusers.
Location of mounting isless critical if external temperature sensors are used
Installation
1. Connect the wires to be connected to the terminals of the power case according to wiring
diagram
2. Install the mounting plate to the flush mounting box. Make sure that the nipple with the front
holding screw is facingto the ground. Make sure the mounting screw heads do not stand out
more than 5 mm (0.2”) off the surface of the mounting plate.
3. Ensure that the jumpers are set correctly.
4. Slide the two latches located on the top of thefront part into the hooks at the upper side of
the mounting plate.
5. Carefully lower the front part until the interconnector reaches the mounting-plate. Continue
pressing in a gentle way until the front part isfully connected.While inserting the connectors,
a slight resistance can be felt. This is normal. Do not use excessive force!
6. With a Philips-type screw driver of size #2, carefully tighten the front holding screw to secure
the front part to the mounting plate. This screw is located on thefront lower side of the unit.
There is no need to tighten the screw toomuch.
Display and Operation
Power Failure
Upon power-interruption,all parameters and setpoints are memorized in non-volatile memory and therefore do not
have to be re-entered again.
Error messages
Err1: The connection tothe temperature sensor may be interrupted or the temperature sensor is damaged.
The output is switched off. Verify parameter settings and wiring.

Configuration parameters for firmware version 1.3
The TCY-FT-U is preset to work for most applications. For special requirements it can be fine tunedto work
ideal with a simple parameter setup routine.The parameterscan be changed on the unit without the need of
additional equipment.
Identifying the firmware version
The parameters andfunctionality of controller depend on its firmwareversion and revision. Itis therefore
important to use a matching product version and parameter set. The Firmwareversion and revision version
can be found when pressing simultaneously the and keys during several seconds. On the upper 7
segment display, the firmware version can be found, on the lower 7 segment display the current revision
index (or “sub-version”).
Setting of user parameters
The TCY-FT-U can be adapted to fit perfectly into your application. The control operation isdefined by
parameters. The parameters are set during operation by using the control buttons.
The parametersmay only be accessed by entering a code. There aretwo levels of parameters: User
operation parametersfor access control settings, and Expert parameters for controlfunctions and unit setup.
The codes for user levels and expert levels are different. Only control experts should be given the control
parameter code.
The parameters can be changed as follows:
1. PressUP and DOWN button simultaneously for three seconds. The display shows the software
version in the large digitsand the product codein the small digits.
2. Pressing the OPTION button will indicate CODE on the small digits and 000 on thelarge digits.
3. The code for accessing the user parameters is 009
4. Select this using UP or DOWN buttons.
5. Press OPTION button after selecting the correct code.
6. Once logged in, the parameter is displayed immediately.
7. Select the parameters with the UP/DOWN buttons. Change a parameter by pressing the OPTION
button. Three triangleswill show up on the lower right and indicate thatthe parametermay be
modified now. Use UP or DOWN buttonsto adjust the value.
8. After you are done, press OPTION or POWER in order to returnto the parameter selection level.
Press the POWER button again so as to leave the menu. The unit will return to normal operation if no button
is pressed for more than 5minutes.

Configuring the function of the external input X1
The external input X1 may be configured for several functions:
CP18 = 0
External control
input
The control input is provided by the external input. The
internal input will not be used.
CP18 = 1
Switching Economy
and Comfort modes
Economy (unoccupied) and Comfort (occupied) modes
are controlled through an external contact by connecting
X1 through a dry contactto signal common. This function
may be used together with key card switches for hotels or
motion detectors for offices.
CP18 = 2
Switching Energy
Hold OFF and
Comfort modes
Opening the external temperature input will force the unit
into the OFF operation mode. The operation mode cannot
be overridden by using theterminal. Connectingthe
binary input to GND returns control of the operation mode
to the terminal. Thisfunction may be used as window
contact to prevent loss of energy.
CP18 = 3
Key card function
As with CP18 = 1, the key card function switches
economy (unoccupied) and comfort (occupied) modes.
Instead of using the setpoint shift, the setpoints in
unoccupied mode are defined by parameter CP20 and
CP21.
CP18 = 4
Output enable
This may be used for a dewpoint sensor input. Output will
switch off if contact opens.
Configuring auto changeover input X2 (TCY-FT2-U only):
The auto changeover function automatically changes heating and cooling mode based on supply
media temperature or outdoor temperature.The difference between the two is in the values of the
changeover limits CP23 and CP24. See table below for recommended settings.
Heating and cooling may be as well changed by an open contact switched to signal ground. Note: all
signal ground levelsof involved controllersmust be the same in case more than one controller is
switched.
