Ariston CLAS X 28 FF NG

Clas X is a series of wall-mounted dual- and single-circuit boilers with open and closed combustion chambers, with capacities ranging from 24 to 35 kW. Each boiler features a built-in 8-liter expansion tank, a two-speed pump with automatic speed control, a stainless steel DHW heat exchanger (dual-circuit models), a three-way valve with a servo drive, and an immersion sensor (single-circuit models).

The control board has a built-in digital BusBridgeNet bus, which allows you to connect an outside temperature sensor and a remote control panel with the Sensys room temperature sensor function to the boiler.

Expansion units also allow weather-compensated control of high- and low-temperature heating zones (up to 6 zones). Connection to a solar system is possible. Control is via buttons and an LCD display.
