Fan Coil Controller TLC3-FCR-M-230
Configuration parameters for firmware version 3.0
The TLC3-FCR-M 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.

FC 04
Economy (unoccupied) Mode temperature shift:
The comfort (occupied) setpoint is shifted by the value
set with parameter. If heating is active the comfort
setpoint will be decreased, if cooling is active, the
setpoint will be increased. (Enable with UP06.)
FC 05
Switching Span Heating,
Setting this value to 0 limits fan to single fan speed in
heating mode
FC 06
Switching Span Cooling
Setting this value to 0 limits fan to single fan speed in
cooling mode
FC 07
Switching Hysteresis is the difference between
switching on and switching off. A small hysteresis will
increase the number of switching cycles and thus the
wear on fan and relays contacts.
FC 08
Mold Protection:
In mold protection, the fan keeps running independent
of temperature as long as the unit is switched on.
FC 09
Switching delay min running time of fan speed. Prevents
the fan from switching in too short intervals.
FC 10
Switching delay min stopping time of fan speed.
Prevents too short restart times, once a fan speed has
been switched off.

Heat/Cool Changeover Delay (if set to FC11 = 3):
A demand to switch between heating and cooling must
persist for the length of time set with this parameter
before the controller switches. Prevents activation of a
sequence during a short-term change in temperature in
order to protect equipment (with control overshoot for

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.

External control
The external sensor is the control input. The internal

sensor will be disabled.
FC19 = 2
Switching Economy
Economy (unoccupied) and Comfort (occupied) modes
and Comfort 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
Opening the input will force the unit into the OFF
Hold OFF and
operation mode. The operation mode cannot be
overridden by using the terminal. Connecting the input to
Comfort modes
signal common returns control of the operation mode to
the terminal. This function may be used as window
contact to prevent loss of energy.
Heat – Cool
FC19 = 4
Switch heating and cooling mode based on supply media
changeover
or outside temperature or binary contact. See below for
further details.
FC19 = 5
Key card with
As with FC19 = 2, the key card function switches economy
alternative setpoint
(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.
Recommended settings for FC21 and FC22:
