CF-MC Master Controller

Application

Accessories

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
