Product Information
Benefits
Equipped with the industry's first intelligent combustion
management system and powerful control technology,
the new generation Vitocrossal 300 CU3A gas-fired
Floor mounted condensing boiler delivers unparalleled
performance, reliability and comfort.
The benefits at a glance:
■ Best value in its class with new industry-leading
technology and the most standard features.
■ Highest Efficiency up to 98% at full modulation and up
to 95% A.F.U.E.
■ Lasting performance with industry-leading Viessmann
made SA240 316 Ti stainless steel Inox-Crossal heat
exchanger constructed to CSA B51 and ASME Section IV.
■ Low Emission Combustion with Viessmann made
stainless steel MatriX burner. Factory calibrated.
■ Fast Installation and Reduced Maintenance with
Lambda Pro, industry-first intelligent combustion
management system: Adjusts automatically to gas
type and quality. No fuel conversion kit required.
■ Powerful and User-friendly Viessmann Vitotronic on-
board multi-function outdoor reset boiler and system
control for multi-temperature space and DHW heating.
■ Zone circuit capabilities provide 3 input connections
that allow easy integration of third party components
such as thermostats, SIM controls, Multizone controllers,
and other smart or on/off control technologies.
■ The setup of these new capabilities can be done
quickly with the start-up wizard that prompts the
installer for the relevant information necessary to
setup the system without having to go into complex
levels of coding parameters.
■ The unique capability of the zone circuit control allows
the installer to combining temperature setpoint operation
and outdoor reset capability. This means that one or all
of the 3 zone circuits control can operate on a set
temperature, or vary based on the outdoor reset curve
that is selected in the start-up wizard.
