Chapter 2 Introduction to RCF
RCF fan coil controllers
RCF is an extensive range of fan coil controllers for control of heating, cooling and fan
control. RCF enables you to create anything from stand-alone systems for managing the
functions in a single room to large, integrated SCADA systems.
Models of RCF that feature the letter “C” in their designation (e.g. RCF-230CTD) offer
built-in communication. Controllers featuring communication can be connected to bus lines,
such as Modbus, Regin’s bus system EXOline or BACnet, in order to communicate with a
central SCADA system via RS485.
Applications The RCF line of controllers offer appealing design and functionality. They are suitable in
buildings where a high level of comfort and low energy consumption are desired, such as
offices, schools, shopping centres, airports, hotels and hospitals.
Models are available for control of analogue, thermal, and three-position actuators, as well as
models offering thermostat functions. There are models for control of either an EC fan or of
a three-step fan-coil unit.
Mounting The modular design with a separate bottom plate for wiring makes all controllers in the RCF
line easy to install and commission. Mounting takes place directly on the wall or on a device
box.
RCF with communication
Communication The controllers can be connected to a central SCADA system via RS485 (EXOline, Modbus
or BACnet) and configured for a specific application using the configuration software Regio

manual.
RCF-230CD, RCF-230CAD and RCF-230CTD are BTL listed from software version 1.2-1-
00 (BACnet stack 3.0.4).
Control The controllers can be configurered for the following control modes/control sequences:
• Heating or cooling via change-over function
• Change-over/Heating (Only RCF-230(C)TD and RCF-230CTD-EC, which is
configured for electric heater)
• Heating/Cooling
