OEM Alpha direct: System

• Classic room-by-room temperature control that makes no compromises

• A range of different factors influence people’s feeling of well-being. Optimum distribution of heat plays a major role in making homes feel cosy.
• The majority of people like the radiant heat emitted by panel heating systems which ensure perfect distribution of heat. To function well, room-by-room temperature control needs to be highly precise and energy-efficient.
• It also has to offer a high degree of precision to adjust heating and cooling functions to people’s needs as best as possible.
• The OEM Alpha direct: System is a room-by-room, wired temperature control system by Möhlenhoff in a modern design.
• All components in this traditionally wired room-by-room temperature control unit can be used independently or as part of a system. The control types and basic designs can be combined into one room-by-room temperature control system.
• The result is a response to simple as well as complex requirements for heating and cooling applications that tick all the boxes.
• The portfolio is complemented by a new room thermostat for the switch range that can be used for both water-based and electric underfloor heating systems.
