Installation Guide CF-MC Master Controller

1. Introduction

The CF-MC Master Controller is a part of the new trend-setting CF2+ wireless hydronic floor heating
control system from Danfoss. Based on 2-way wireless communication technology CF2+ offers high
transmission safety, easy wireless installation, a high level of individual room temperature control,
and thus optimal comfort and improved energy efficiency.
The system has a variety of beneficial features and easily accessed application functionalities. This
includes a CF-MC Master Controller with short-circuit protected outputs, regulation by Pulse Width
Modulation (PWM) principles, away function, separate relays for both pump and boiler control, self­diagnostic 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 CF-RC
Remote Controller, and CF-RU Repeater Unit for extended wireless range.

4. Mounting and Installation Procedure (Sequential)

The wireless systems transmission range is sufficient for most applications; however wireless signals
are weakened on the way from the CF-MC Master Controller to the Room Thermostats and each
building has different obstacles.

Checklist for optimal installation and best wireless signal strength (fig. 3):

• No metal objects between the CF-MC Master Controller and the Room Thermostats.

• Wireless signal through walls on shortest possible diagonal distance.

• Optimise the wireless signal by installing a CF-RU Repeater Unit.

Note! Danfoss recommends that an installation plan is made before beginning the actual installation.

4.1 CF-MC Master Controller

Mount the CF-MC Master Controller in an horizontal upright position.

Wall:

• Remove the front cover (fig. 4).

• Mount with screws and wall plugs (fig. 5).

DIN-Rail:

• Mount DIN-rail parts (fig. 6).

• Click on DIN-rail (fig. 7).

• Release from DIN-rail (fig. 8).

Important! Complete all the installations on the CF-MC Master Controller described below, before
connecting to a 230 V power supply!

4.2 24 V Actuators

• Connect the two actuator wires to an output (fig. 9).

• Fix the cable - round cable (fig. 10), squared/flat cable (fig. 11).

Note! If NC (normally closed) actuators are installed for Pulse Width Modulation (PWM) regulation for
floor heating, no further actuator output configuration is needed (see chapter 6.1).

4.3 Relays for Pump and Boiler Control

• Pump: Connect the live wire (L) across the Pump Relay from an external power supply. Make
sure the power supply is switched off. Then connect the live wire, and complete other connec­ tions to the pump in accordance with existing law (fig. 12).

• Fix the cable (fig. 13).

• Boiler: Connect the live wire (L) across the Boiler Relay from an external power supply. Make
sure the power supply is switched off. 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 therefore NOT be used as direct
power supply. Max. load is 230 V and 8 A/2 A (inductive)!

4.4 Input for Away Function

• Connect the two wires from an external switch (ON/OFF) to the two terminals for the Away Func­ tion input (fig. 14).
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 (fig. 15).

GB

Note! The Away Function ensures a set room temperature fixed at 8 °C for all Room Thermostats, but it
can be changed with the CF-RC Remote Controller.
If the system is configured for cooling, a dew-point sensor can be connected instead of an external switch.

4.5 Input for Heating and Cooling

• Connect both wires from an external switch (ON/OFF) to the terminals for heating and cooling
input (fig. 16).
With the switch closed (ON), the system will switch from heating to cooling mode.

• Fix the cable (fig. 17).

Note! With the system in cooling mode, the actuator output will be activated (ON for NC actuators/OFF
for NO actuators), when the temperature in a room exceeds the set point +2 °.
When the system is in cooling mode a dew-point sensor should be installed, connected to the Away Func­tion input and placed on the primary supply side.

Note! If the power supply plug is removed from the power supply cable during installation, ensure that the
connection is made according to existing law/legislation.

4.8 CF-EA External Antenna

The CF-EA 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 CF-MC Master Controller is located in a
metal cabinet/box.

• Remove the plastic cover from the antenna connection on the CF-MC Master Controller (fig. 18).

• Connect the CF-EA External Antenna (fig. 19).

• Place the CF-EA External Antenna on the other side of the transmission barrier away from the

IMPORTANT!

As heat emission from the floor may vary slightly depending on floor covering - and thereby cause inaccu­rate temperature measurement - it may be necessary to adjust the setting of max. and min. floor surface
temperatures accordingly. It is important always to follow recommendations from the floor manufacturer
regarding max. floor surface temperature. It is recommended to include mixing shunt for floor heating
circuits in order to ensure optimal flow temperature. - In addition to minimised energy consumption, cor­rect setting of the flow temperature will eliminate the risk of excessive heat transfer to the floor.
