Argus-RC-CDO

Pre-programmed room controller with display

and communication

• Awarded design

• Communication via RS485 (Modbus or EXOline)

• Fast and safe conﬁguration via Regio tool

• Simple installation

Argus-RC-CDO is a complete pre-programmed room

controller from the Argus series intended to control

heating and cooling in a zone control system.

• On/Off or 0...10 V control

• Backlit display

• Input for occupancy detector, window contact,

condensation detector and change-over function

Argus-RC-CDO is a room controller from the Argus

series. It has a display and communication via RS485

(Modbus or EXOline) for integration into systems.

Argus

Argus is a wide series of controllers which handle heating

and cooling.

The controllers are divided into three different series;

pre-programmed, stand-alone controllers, freely

programmable controllers with communication and

pre-programmed controllers with communication, to

which Argus-RC-CDO belongs.

Applications

The Argus 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 3.

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 sensor. An external

Pt1000-sensor can also be used.

Actuators

Argus-RC-CDO can control 0...10 V DC valve actuators

and/or 24 V AC thermal actuators.

Easy to install

The modular design with a separate bottom plate for

wiring makes the whole Argus 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

Argus-RC-CDO can be connected to a central

SCADA-system via RS485 (EXOline or Modbus) and

conﬁgured for a particular application using the cost-free

conﬁguration tool Regio tool

. Read more about Regio

RC-CDO coil. controller is in Off-mode. When the temperature exceeds 22°C, the output function is set to heating and when the temperature drops below 18°C, the output is set to cooling. As an alternative, a potential-free contact can be used. When the contact is open the controller works with the heating function and when it is closed, with the cooling function. Actuator exercise All actuators are exercised. The exercise takes place at set intervals in hours (FS=23 hours interval).
