Installation Guide CF-MC Master Controller401/2016 VIUHK902 Danfoss Heating Solutions1. IntroductionThe CF-MC Master Controller is a part of the new trend-setting CF2+ wireless hydronic floor heatingcontrol system from Danfoss. Based on 2-way wireless communication technology CF2+ offers hightransmission 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. Thisincludes a CF-MC Master Controller with short-circuit protected outputs, regulation by Pulse WidthModulation (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 ofRoom Thermostat, easy wireless system access and extended functionality via the optional CF-RCRemote Controller, and CF-RU Repeater Unit for extended wireless range.2.

Mounting and Installation Procedure (Sequential)The wireless systems transmission range is sufficient for most applications; however wireless signalsare weakened on the way from the CF-MC Master Controller to the Room Thermostats and eachbuilding 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 ControllerMount 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, beforeconnecting to a 230 V power supply!
