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.

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.
