General Description

The TLC3-FCR-2 is a stand-alone electronic fan coil controller with one control loop. The TLC3-FCR-2 features 1 NTC temperature sensor input and five binary outputs. Three outputs control a fan with low, medium and high fan speeds. Two binary outputs may be used to control either two spring return or thermal valves or one three point floating valve.

A detailed parameterization is possible with the use of a simple configuration routine. The TLC3-FCR-2 can be configured using the standard operation terminal. No special tools or software is required.

TLC3-FCR-2 Engineering Manual

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 exter nal 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.

Setting of user parameters

The TLC3-FCR-2 is an intelligent controller and can be adapted to fit perfectly into your fan coil application. The control operation is defined by parameters. The parameters are set during operation by using the standard operation terminal.

The parameters are password protected. There are two levels of parameters: User operation parameters for access control settings and Expert parameters for control functions and unit setup. The passwords for user levels and expert levels are different. Only control experts should be given the control parameter password.

The parameters can be changed as follows:

1. Press UP and DOWN button simultaneously for three seconds. The display will indicate the firmware version in the upper large digits and the revision in the lower small digits. Pressing any key will show: CODE.

2. Select a password using UP or DOWN buttons. Select 009 in order to get access to the user parameters, 241 for controls parameters. Press OPTION after selecting the correct password.

3. Once logged in, the parameter is displayed immediately

4. Select the parameters with the UP/DOWN keys. Change a parameter by pressing the OPTION key. The MIN and MAX symbols show up and indicate that the parameter may be modifi ed now. Use UP and DOWN key to adjust the value.

5. After you are done, press OPTION or POWER in order to return to the parameter selection level.

6. Press the POWER key again so as to leave the menu. The unit will return to normal operation if no key is pressed for more than 5 minutes.

Control configuration

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.

Control Parameters (Access code: 241)

Warning! Only experts should change these settings! See user parameters for login procedure.

Parameter Description Range Standard

FC 00 Minimum setpoint limit in Heating mode -40…60°C (160°F) 16°C (61°F) FC 01 Maximum setpoint limit in Heating mode -40…60°C (160°F) 24°C (75°F) FC 02 Minimum setpoint limit in Cooling mode -40…60°C (160°F) 18°C (64°F) FC 03 Maximum setpoint limit in Cooling mode -40…60°C (160°F) 30°C (86°F)

Controls configuration

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 disables the auto fan speed function in heating mode

FC 06 Switching Span Cooling

Setting this value to 0 disables the auto fan speed function 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 0…255s 10s FC 10 Switching delay min stopping time of fan speed 0…255s 10s FC 11 Control option:

0 = Cooling only

1 = Heating only

2 = 2-pipe system

3 = 4-pipe system FC 12 Dead Zone Span:

The Dead Zone Span lies between the heating and the

cooling setpoint. The output is off while the temperature

is within the dead zone span. A negative dead zone is not

possible. FC 13 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

example)

Î 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.

Output configuration

FC 16 Output setting, Binary, PWM or 3-point:

0 = Binary or PWM (DO4 Heating, DO5 Cooling)

1 = 3-point binary output (DO4 open, DO5 close)

2 = 3-point floating output (DO4 open, DO5 close) FC 17 Running Time in 3-point mode 0…255 s 90 s FC 18 FC 19

Î 3-point floating:

For floating point outputs the running time o f the actuator used needs to be specified with F C 17. Running time is defined as the time required for the actuator to run from fully open to fully closed and vice versa. Actuators with a fixed running time are recommended. Once fully open or fully closed the running time for the actuator is extended for a full run-time cycle. This will allow the actuator position to be synchronized in case it has been moved during off time or an actuator with variable running time was used.

Î Pulse With Modulation (PWM)

In PWM mode the digital output will be switc hed on/off once per cycle. The on and off times are calculated according to the control sequence.

PWM cycle time cooling, 0 disables PWM mode 0…100 min 0
