function

RC-C3DOC is a room controller from the Regio series.

It has a display and communication via RS485 (Modbus,

BACnet or EXOline) for integration into systems.

Regio

Regio is a wide series of controllers which handle heating

and cooling.

The controllers are divided into three different series,

Mini, Midi and Maxi. Mini are pre-programmed,

stand-alone controllers. Maxi consists of freely

programmable controllers with communication.

The Midi group, to which RC-C3DOC belongs, are

pre-programmed controllers with communication.

Applications

The Regio controllers are suitable in buildings where you

want optimal comfort and low energy consumption, for

example ofﬁces, schools, shopping centres, airports, hotels

and hospitals etc.

See application examples on page 4.

Design

The controllers have a modern design. The

design has been awarded the 2007 “iF product

design award”.

Sensor

The controller has a built-in temperature

sensor. An external PT1000-sensor can also be used.

There is also an input for a CO

- sensor.

Actuators

RC-C3DOC can control 0...10 V DC actuators for valves

or dampers and/or 24 V AC thermal or On/Off spring

return actuators and damper.

Easy to install

The modular design with a separate bottom plate for

wiring makes the whole Regio series easy to install and

commission. The bottom plate can be put into place

before the electronics are installed. Mounting is directly

on the wall or on an electrical connection box.

Flexibility with communication

RC-C3DOC can be connected to a central

SCADA-system via RS485 (EXOline, BACnet or

Modbus) and conﬁgured for a particular application using

the cost-free conﬁguration tool Regio tool

RC-C3DOC Off: Heating and cooling are disconnected. However, frost protection is still active (Factory setting (FS)=8°C). Operating mode Off is activated on open window. Display handling The display has the following indications: Forced ventilation Changeable value Occupancy indication Setpoint Indoor / outdoor temp.
PAGE 3
RC-C3DOC When the Occupancy button is held depressed for more than 5 seconds, the controller changes operating mode to ”Shutdown” (Off/Unoccupied), regardless of the current operating mode. Via the display or Regio tool © , you can configure which operating mode, Off or Unoccupied, should be activated on ”Shutdown” (FS=Unoccupied). If you press the Occupancy button for less than 5 seconds in Shutdown, the controller returns to Bypass.
