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.

CF-MC Master Controller includes features like:

•2-way wireless transmission at 868.42MHz, for higher transmission security

•Direct link test option on each system component

•Wireless assignment of room thermostats and other system components

•5 or 10 short-circuit protected outputs with LED indication

•Outputs for 24V NC or NO actuators

•Valve motion for all outputs for approx. 12 min. every 14th day with no heat demand

•PWM (Pulse Width Modulation) principle

•Input (On/Off) for heating / cooling

•Input for PT1000 pipe sensor

•Input (On/Off) for global standby (can also be used for CF-DS dew-point sensor)

•Relay for pump control with automatic pump motion

•Relay for boiler control, activated only at heat demand

•Easy cable fixing at each actuator output for several cable types

•Automatic self diagnosis of errors

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, e.g.

•Individual settings for each Master Controller output

•Override and locking of local room temperature settings

•Setback and period programming

•System status etc.

•Forecast

•Low enrgy optimizer

•Control of cooling applications
