XCC 618

Compensating optimiser for 1, 2-stage modulating burners with 0.10 V DC input

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.
Data communication with other boilers and other controllers via C-Ring connection..
Essential sensors: 1 boiler sensor..
Optional sensor: 1 anticondensing sensor, 1 flue gases sensor, 1 outside sensor.
