The ECL Comfort 300 is an electronic

temperature controller which can be

loaded with selected applications by

means of an ECL card.

The ECL Comfort 300 controller has triac

outputs for motorised valve control

and relay outputs for burner/pump/

changeover valve control.

It is possible to connect up to 6 Pt 1000

temperature sensors and optional plug-

in modules.

The enclosure is designed for wall and

panel mounting as well as for mounting

on a DIN rail.

The ECL card contains information

about application and factory settings.

Each application has its own card with

corresponding settings.

Special applications and/or settings are

possible on request.
