CF-MC is the Master Controller in Danfoss’ CF2+ wireless floor heating control system. 2-way wireless communication between CF-MC and other wireless CF2+ system components ensures a high level of transmission security and makes it possible to perform Link test of the signals. Transmission range is up to 30 m in normal buildings. If transmission is reduced or blocked by building or interior elements, a CF-EA external antenna (accessory) can be used to avoid the obstacles. CF-MC is connected directly to 230 V power supply, and it provides all actuator outputs with with 24 V.Larger CF2+ systems can consist of 2 or 3 CF-MC Master Controllers with up to 30 outputs. Systems with more Master Controllers can be accessed by a single wireless CF-RC Remote Controller, which gives access to even more functionality and features
