CF-MC Master Controller
Application
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
