Produced by Danfoss Floor Heating Hydronics 08.2005

• 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 trans-

mission 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 ap-

plication functionalities. This includes a Master Controller, CF-MC, with

short-circuit protected 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 indica-

tion, 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.

5. Installation Procedure (Sequential)

Important Note: Complete all the installations on the Master Controller

described below before connecting to a 230V power supply !

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 regula-

tion, no further actuator output conguration is needed (see 6.1) !

5.2 Relays for Pump & Boiler Control

• Pump: Connect the live wire (L) across the Pump Relay from an exter-

nal 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 exter-

nal 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.

Note #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 if the application structure in the example is chosen!

5.5 Wiring

5.6 Power Supply

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

installed, connect 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 trans-

mission 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 bar-

rier away from the Master Controller.

5.8 More (2-3) Master Controllers

Notes: Master Controller #1 should be the one connected to the local sup-

plying 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 simulta-

neous 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. 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 and/or boiler etc.

congure the relays for pump and boiler control accordingly (see 6.2)

Note: Later removal of Master Controller #2 or #3 from Master Controller #1

can only be done by resetting Master Controller #1 (see 6.5)

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.

Room Thermostats:

When the transmission test (link test) from a Room Thermostat is re-

ceived by the Master Controller, the assigned output(s) will ash four

times. This makes it possible to identify the outputs to which a Room

Thermostat has been assigned (Fig. 23).
