TLC3-FCR-M-U Fan coil PI-controller, 2-/4-pipe with analog outputs

The TLC3-FCR-M-U is a stand-alone electronic fan coil controller with one control loop option and one PI heating and cooling sequence.

The TLC3-FCR-M2-U is designed for 2-pipe modulating fan coil systems and features one NTC temperature sensor input, one external passive input for temperature or open contact, three binary outputs (relays) and one analog output (0-10 VDC). 

The TLC3-FCR-M4-U is designed for 4-pipe modulating fan coil systems and features one NTC temperature sensor input, three binary outputs (relays) and two analog outputs (0-10 VDC) for heating and cooling.

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