1. Introduction
The CF-MC Master Controller 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 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, 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 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 sucient 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 dierent obstacles.
Checklist for optimal installation and best wireless signal strength (g. 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 (g. 4).
•Mount with screws and wall plugs (g. 5).
DIN-Rail:
•Mount DIN-rail parts (g. 6).
•Click on DIN-rail (g. 7).
•Release from DIN-rail (g. 8).
Important! Complete all the installations on the CF-MC Master Controller described below, before
connecting to a 230 V power supply!
