    How to complete a Vitorondens installation

    • Control: the Vitotronic 100 KC4B handles one circuit without mixer and DHW; almost all components in this collection require the Vitotronic 200 KO2B.
    • Circuits: a direct Divicon for each unmixed circuit; for a lower-temperature circuit, a Divicon with KM-Bus mixing valve, which already includes its extension kit, or the extension kit fitted to the mixing valve of the installation. With 2 or 3 groups, a manifold with its wall bracket and a low loss header (up to 4.5 or 7.5 m³/h).
    • Remote control: wired, Vitotrol 200-A for one circuit or 300-A for up to 3; radio, Vitotrol 200-RF with its base.

    To compare the BR2A and the J2RA, see Oil condensing boilers.

    Applications

    • Home with radiators and an underfloor heating circuit.
    • Building with 2 or 3 circuits on a manifold and low loss header, with the J2RA.
    • Solar thermal support, with the SM1 module.

    Why buy your Vitorondens from Q-Tech?

    1. Q-Tech is a Viessmann Lead PRO Partner and sells the boiler and its original components from its own stock.
    2. Boiler, Divicon groups and control can arrive assembled and tested in a pre-assembled plant room: see Pre-Montaje Avanzado.
    3. To choose components with the data of your installation: a technical call with an Expert Technician (paid service) or WhatsApp.

    Frequently asked questions

    Is the small manifold mandatory?

    On the BR2A, yes: according to the Viessmann price list it must be included in the order. The J2RA already comes with a safety group.

    Can I use Vitotrol remote controls with the Vitotronic 100?

    No. According to Viessmann, the Vitotrol 200-A, 300-A and 200-RF and the extension kit require the Vitotronic 200 KO2B.

    Can I control the boiler from my phone?

    The BR2A with Vitotronic 200 KO2B, yes, with Vitoconnect OPTO2 and the ViCare app (up to 35 kW, according to viessmann.es). For now, the J2RA is operated from its Vitotronic 200.
