Selection of fans
Do not directly connect devices that exceed 2A. Observe startup current on inductive loads! Do not connect
more than one fan coil unit to one controller.
Modulating Actuators:
Choose actuators with an input signal type of 0-10V DC or 2-10V DC. Observe maximal signal current of
1mA!
Mounting location
Install the controller on an easy accessible interior wall, approx. 1.5 m above the floor in an area of
average temperature.
Avoid direct sunlight or other heat sources, e.g. the area above radiators and heat emitting 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. Slide the two latches located on the top of the front part into the hooks at the upper side of the
mounting plate.
4. 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!
5. 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.
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: Error temperature sensor. The internal temperature sensor may be damaged or not present.
FP: Steady: Frost protection is active.
Blinking: Frost protection activated in the past and is now inactive. Confirm with OPTION key.

Configuration parameters for firmware version 3.0
The TLC3-FCR-M-U can be adapted to wide variety of fan coil applications. The adaptation is done with
parameters. The parameters can be changed on the unit without the need of additional equipment.
Identifying the firmware version
The parameters and functionality of controller depend on its firmware revision. It is therefore important to use
a matching product version and parameter set. The firmware version is shown on the large LCD digits when
pressing UP and DOWN buttons for more than 3 seconds simultaneously.
Changing parameters
The parameters may only be accessed by entering a code. There are two levels of parameters: User
operation parameters for access control settings and Expert parameters for control functions 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. Press UP and DOWN button simultaneously for three seconds. The display shows the
software version in the large digits and the software revision in the small digits.
2. Pressing the OPTION button will indicate CODE on the small digits and 000 on the large
digits.
3. The code for accessing the user parameters is 009, for controls settings it is 241 (scroll
backwards by pressing the DOWN button)
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. The MIN and MAX symbols show up and indicate that the parameter may
be modified now. Use UP or DOWN buttons to adjust the value.
8. After you are done, press OPTION or POWER in order to return to the parameter selection
level.
9. 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 5 minutes.

Proportional control (P-band)
The proportional control function calculates the output based on the difference between setpoint and
measured value. The proportional band (P-band) defines the difference between setpoint and measured
value which will result in a 100% output. Setting the proportional band to 0 disables proportional control.
Integral gain KI
The integral gain defines how fast the output increases in case the setpoint is not met by the room
temperature. A low value indicates a slow reaction, a high value a fast one. If the value is chosen too high,
the controller will start to swing. Depending on the room size and heating / cooling equipment used a value
between 0.1 and 1.5 should be sufficient. Below are suggested values:

Switching Economy
and Comfort modes
Economy (unoccupied) and Comfort (occupied) modes
are controlled through an external contact by connecting
the input through a dry contact to signal common. This
function may be used together with key card switches for
hotels or motion detectors for offices.
FC19 = 3
Switching Energy
Hold OFF and
Comfort modes
Opening the input will force the unit into the OFF
operation mode. The operation mode cannot be
overridden by using the terminal. Connecting the input to
signal common returns control of the operation mode to
the terminal. This function may be used as window
contact to prevent loss of energy.
FC19 = 4
Heat –Cool
changeover
Switch heating and cooling mode based on supply media
or outside temperature or binary contact. See below for
further details.
FC19 = 5
Key card with
alternative setpoint
As with FC19 = 2, 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 FC21 and FC22.
Configuring auto changeover input if FC19 = 4:
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 FC21 and FC22. 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 levels of involved controllers must be the same in case more than one controller is
switched.
