“Less is more” – all new heating systems from Viessmann are designed according to this maxim. The high integration capability achieved in the living area is the aim here. The generosity and clarity of the single part cover in conjunction with the central control unit and a full protective flap covering the programming elements result in an architecturally pleasant appearance, which suggests safety and quality. All main functions have been reduced to the essentials and are concentrated onto two rotary toggles integrated onto the front of the programming unit. Access for servicing and maintenance requires only two steps; the removal of the single part housing and of the front of the control unit from the wiring chamber. The uniform design and identical brand image ensure a formal identity of the entire product range, which assists orientation and creates trust.
