Quick guide from the manual
The Danfoss CF-RC Remote Controller is designed for the CF2 heating system. Key installation steps include installing all Room Thermostats first, removing the battery strip to activate the remote, and performing the assignment to the Master Controller within 1.5 meters. Always verify transmission with a link test before final wall mounting.
Functional Overview
The front of the device features a display, two soft keys, and up/down/left/right selectors for menu navigation. Icons on the display indicate system alarms, communication status with the Master Controller, power supply status, and low battery warnings.
Installation
Master Controller: Activate the Install mode on the Master Controller. The install LED will flash, then turn solid when active.
Remote Controller: Once batteries are connected, follow the on-screen installation guide to select the language. Set the time and date using the selectors. You can name the rooms where the Room Thermostats are placed to simplify system management.
Mounting
The Remote Controller can be wall-mounted using the included back plate/docking station. This allows for a 230V power supply connection via the included transformer. When not in the docking station, the unit is powered by two AA 1.5V alkaline batteries. Always perform a link test from the desired location before mounting.
Menus
