  • TELEMANAGEMENT : Enabled using ACB 400 accessory.

APPLICATION

Designed for the total control of burner/boiler (condensation or not).
The 1, 2-stage or modulating burner can be controlled by switches or via the 0…10 V input.
By equipping all the boilers present on site with XCC 618, and a single boiler with XTC 638, 
you can achieve a sophisticated sequence with 1, 2-stage or MODULATING BURNERS and so obtain
the maximum SEASONAL OUTPUT. The whole system is especially suitable also for CONDENSATION BOILERS.

  • Communication with other controllers via serial C-Ring protocol.

Essential sensors:

  • 1 boiler sensor

Optional accessories:

  • 1 anticondensing sensor, 1 flue gases sensor, 1 outside sensor

FEATURES

  • Power supply: 230 V~: Consumption: 5 VA; Modular housing DIN 105 x 115; Protection: IP 40 

  • Digital programming by means of 4 keys and alphanumeric display.

  • Control of boiler temperature at set point or according to the request of the various users via C-Ring (if the controllers are COSTER) or by a 0…10 V– signal.

  • Control of a 1- or 2-stage or modulating burner.

  • Option of sequence under control of XTC 638.

  • Automatic change GMT/BST

  • Periodic operation of summer site exercise of valves and pumpse.

  • Metering of degree-days, of burner operating hours and of number of starts.

  • Alarms for short or open circuits to sensors and for functional faults site and devices.

  • C-Ring connection for local exchange of data with other COSTER controllers.

  • Option of C-Bus connection for exchange data with local PC or remote Telemanagement PC..

    XCC 618 is provided with a 0…10 V output adaptable to any generator fitted with this input.
    XCC 618 is also provided with a 0…10 V input for control AS POWER or AS TEMPERATURE
