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 has been reduced to a minimum to allow for
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 radiators and
heat emitting electrical equipment.
Avoid locations behind doors, outside walls and below or above air discharge grills and
diffusers.
Location of mounting is less 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 facing to 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 the front 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 is fully 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 the front lower side of the unit.
There is no need to tighten the screw too much.
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 to the temperature sensor may be interrupted or the temperature sensor is damaged.
The output is switched off. Verify parameter settings and wiring.
