Instruction CF-MC Master Controller

1. Introduction

• The Master Controller, CF-MC, 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 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.
