VITODENS 200-W

Featuring Viessmann’s unique energymanagement system

Intelligent Lambda Pro gas management system for

optimum efficiency and performance

The Lambda Pro is designed to work efficiently irrespectiveof gas quality – a factor which will become increasinglyimportant as international gas supplies become less reliable.

The Lambda Pro combustion controller works alongside theburner to constantly monitor the air to gas ratio. Instead ofthe gas/air mix remaining fixed from commissioning, the mixis self adjusting as required, to maintain optimum boilerefficiency in relation to the gas quantity – in a similar way tothe fuel management system in a car engine.

The control also replaces the traditional gas valve control andchanging to LPG takes just a few seconds – with no changingof any parts.

Modulating MatriX pre-mix burner

Developed by Viessmann, the stainless steel MatriX pre-mixburner burns with thousands of tiny flames instead of onelarge one, to distribute heat cleanly and efficiently to the heatexchanger.

With a modulation range of 1:4 the heat demand is optimisedand maximum efficiency levels are achieved. The extremelylow NOx and CO emissions meet or exceed all national cleanair regulations and guidelines.

The stainless steel MatriX mesh ensures long term reliability.

Inox Radial heat exchanger

As with all Viessmann wall-hung boilers, the Vitodens 200-Wfeatures Viessmann’s unique stainless steel heat exchanger,designed for long term reliability, high performance and self-cleaning.

The design of the heat exchanger ensures high heat transferthrough laminar hot gas flow across defined gaps. Highcorrosion resistance is maintained by the use of high gradestainless steel 1.4571 and thick walls. This component is soreliable that it comes with a 10 YEAR WARRANTY againstcorrosion.

Advanced controls

The Vitodens 200-W is loaded with features and functions tomake installation, maintenance and servicing easy. Theseinclude in-built software for remote data communication andmonitoring, additional heating circuits, a solar/heat pumpinterface, safety monitor sensors and automaticcommissioning functions.

Weather compensation controls

The Vitodens 200-W is available with optional weathercompensation controls (the Vitotronic 200). Constant, smalladjustments in the boiler flow temperature, in response tochanges in the outside temperature, enable the boiler to runcost effectively and efficiently at lower temperatures,condensing for longer. This results in additional fuel savingsof up to 15%.

Boiler Controls

Cascade controls (Vitotronic 300-K)

The Vitotronic 300-K weather compensated cascadecontroller can regulate up to four Vitodens 200-W boilers as asingle heating centre. By communicating with the individualboiler controls, the Vitotronic 300-K ensures that the boileroutput is automatically matched to the heat demand. As aresult, subject to the demand, either one boiler modulates orall four boilers operate concurrently.

FUNCTIONS:

Weather compensated regulation of system/boiler watertemperature of a multi boiler system with up to 4Vitodens 200-W with Vitotronic100, type HC1(modulating temperature) and the flow temperature ofthe heating circuits with mixer
