CF2+ Wireless Floor Heating Control System
CF-MC Master Controller
Application
CF-MC is the Master Controller in Danfoss’ CF2+
wireless oor heating control system.
2-way wireless communication between CF-MC
and other wireless CF2
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
+
system components
• PWM (Pulse Width Modulation) principle
• Input (On/O) for heating / cooling
• Input for PT1000 pipe sensor
• Input (On/O) 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 xing at each actuator output for
several cable types
• Automatic self diagnosis of errors
Larger CF2
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
