1. Introduction

• The Master Controller, CF-MC, is a part of the new trend-setting CF2 wireless

hydronic oor heating control system from Danfoss. Based on 2-way wireless

communication technology CF2 oers high transmission safety, easy wireless

installation, a high level of individual room temperature control, and thus optimal

comfort and improved energy eciency.

• The system has a variety of benecial features and easily accessed application

functionalities. This includes a Master Controller, CF-MC, with short-circuit protect-

ed outputs, regulation by ON/OFF or Pulse Width Modulation (PWM) principles,

global standby, separate relays for both pump and boiler control, self-diagnostic

program and error indication, wireless transmission (link) test possibility on each

type of Room Thermostat, easy wireless system access and extended functionality

via the optional Remote Controller, and Repeater Unit for extended wireless range.

4. Mounting

4.1 Wall

• Remove the front cover (g. 3)

• Mount with screws and wall plugs (g. 4)

4.2 DIN-Rail

• Mount DIN-rail parts (g. 5)

• Click on DIN-rail (g. 6)

• Release from DIN-rail (g. 7)

Note: The Master Controller should be mounted in an horizontal upright position

5. Installation Procedure (Sequential)

Important Note: Complete all the installations on the Master Controller described below before

connecting to a 230V power supply !

Instruction CF-MC Master Controller

VI.UH.K3.1C Produced by Danfoss Floor Heating Hydronics 03.2007

GB

5.1 24V Actuators

• Connect the two actuator wires to an output (g. 8)

• Fix the cable

Round cable (g. 9)

Squared/at cable (g. 10)

Note: If NC (normally closed) actuators are installed for ON/OFF regulation, no further actuator

output conguration is needed (see chapter 6.1) !

5.2 Relays for Pump & Boiler Control

• Pump: Connect the live wire (L) across the Pump Relay from an external power

supply. Make sure the power supply is switched o. Then connect the live wire,

and complete other connections to the pump in accordance with existing law.

(g. 11)

• Fix the cable (g. 12)

• Boiler: Connect the live wire (L) across the Boiler Relay from an external power

supply. Make sure the power supply is switched o. Then connect the live wire,

and complete other connections to the boiler in accordance with existing law.

Note: The relays for pump and boiler are potential free contacts and can thus NOT be used as

direct power supply. Max. load is 230V and 8A / 2A (inductive) !

5.3 Input for Global Standby

• Connect the two wires from an external switch (ON/OFF) to the two terminals for

the Global Standby input. (g. 13)

When this switch is closed (ON) the system will override the current set point for

all the room thermostats and change it to 8°C

• Fix the cable. (g. 14)

Note: The Global Standby ensures a set room temperature xed at 8°C for all Room Thermostats,

but it can be changed with the Remote Controller, CF-RC.

5.4 Input for Heating & Cooling

• Connect the two wires from an external switch (ON/OFF) to the two terminals for

the heating and cooling input. (g. 15)

When this switch is closed (ON) the system will switch from heating to cooling

mode.

• Fix the cable. (g. 16)

Note :

#1: When the system is in cooling mode the actuator output will be activated (ON when NC

actuators / OFF when NO actuators) when the temperature in a room exceeds the set point.

#2: When the system is in cooling mode an independent dew-point alarm function should be

installed.

Danfoss oers the below listed components (see example g. 17)

EDA-24V: Electronic dew-point alarm - 088H3001

EDA-S: Dew-point sensor - 088H3011

TWA-A: 24V-NO actuator – 088H3111

RA-C 20: Danfoss cooling valve* - 013G3096

• This valve must be dimensioned according to the placement on the primary side

in the application structure if the example is chosen!

5.6 Power Supply

• When all actuators, pump and boiler controls and other inputs are installed, con-

nect the Master Controller’s power supply plug to a 230V power supply. (g. 18)

Note: If the power supply plug is removed from the power supply cable during installation make

sure that the connection is made according to existing law/legislation.

5.7 External Antenna (CF-EA)

Note: The External Antenna is installed as diverter when there is NO transmission possible

through a large building, heavy construction or metal barrier, e.g. if the Master Controller is

located in a metal cabinet/box

• Remove the plastic cover from the antenna connection on the Master Controller.

(g. 19)

• Connect the External Antenna. (g. 20)

• Place the External Antenna on the other side of the transmission barrier away

from the Master Controller.

5.8 More (2-3) Master Controllers

Note: Master Controller #1 should be the one connected to the local supplying pump.

Up to 3 Master Controllers can be connected in one system.

If there are 2 or 3 Master Controllers, connect them to a 230V power supply within

a distance from Master Controller #1 that allows simultaneous handling of all the

Master Controllers

Activate Install mode on Master Controller #1(g. 21)

• Use the menu selection button to select the Install mode. Install LED ashes

• Activate Install mode by pressing OK . Install LED goes ON

Initiate installation on Master Controller #2 or #3(g. 21/22)

• Activate installation to Master Controller #1 by pressing OK

• Install LED and ickers during communication and goes OFF when

installation is complete

• Relocate Master Controller #2 and/or #3 if necessary. Link test will be initiated

automatically on reconnection to 230V power supply

• If Master Controller #2 and/or #3 has it’s own pump, the relays for pump and

boiler must be congured accordingly (see chapter 6.4)

Note: Later removal of Master Controller #2 or #3 from Master Controller #1 can only be done by

resetting Master Controller #1 (see chapter 7.2)

5.9 Other System Components

Note: The Installation procedure of other system components to the Master Controller (Room

Thermostats, Remote Controller, and Repeater Unit ; see chapter 2.) is described in the enclosed

instructions for these system components. Please see these instructions for specic installation

procedures

5.10 Transmission Test (Link Test)

Note: The transmission test (link test) between the Master Controller and other system components,

is initiated from the other system components like Room Thermostats, Repeater Unit, Remote

Controller, etc.

Please see the enclosed instruction for these components for transmission test (link test) procedures.

and the output selection button

• Reconnect the 230V power supply to the Master Controller and release the three

buttons when the power LED and all the output LEDs are ON

• The Master Controller is reset when all output LEDs then goes OFF

Resetting the Room Thermostats, CF-RS, -RP, -RD and -RF – g 24:
