RC-C3DOC...Pre-programmed room controller with display and communication RC-C3DOC... is a complete pre-programmed room controller from the Regio Midi series intended to control heating, cooling and CO2 in a zone control system. ✓ Communication via RS485 (Modbus, BACnet or EXOline) ✓ Quick and simple configuration via Application Tool ✓ Input for occupancy detector, window contact, condensation sensor, CO2 detector or changeover function ✓ Supply air temperature limitation The Regio controllers are suitable for use in buildings requiring optimum comfort and reduced energy consumption, such as offices, schools, shopping centres, airports, hotels and hospitals etc. RC-C3DOC... is a room controller in the Regio series. It has display and communication via RS485 (Modbus, BACnet or EXOline) for systems integration. The controller has a built-in room temperature sensor. An external sensor for room temperature, change-over or supply air temperature limitation can also be connected (PT1000). There is also an input for CO2 sensors. RC-C3DOC... can control 0...10 V DC valve actuators and/or 24 V AC thermal actuators or On/Off actuators with spring return and dampers. HEAD OFFICE SWEDEN E-mail: [email protected]

RC-C3DOC... can be connected to a central SCADA system via RS485 (EXOline, BACnet or Modbus) and configured for a specific application using the free configuration software Application Tool. The modular design, featuring a separate bottom plate for wiring, makes the entire Regio range of controllers easy to install and commission. The bottom plate can be put into place before the electronics are installed. Mounting takes place directly on the wall or on an electrical connection box. The display has the following indications: The buttons on the controller enables easy setting of parameter values...

Off: Heating and cooling are disconnected. However, frost protection is still active (factory setting (FS))=8°C). This mode is activated if a window is opened. Unoccupied: The room in which the controller is placed is not used for a extended time period, such as during holidays or long weekends. Both heating and cooling are kept within a temperature interval with configurable min/ max temperatures (FS min=15°C, max=30°C). Stand-by: The room is in an energy saving mode and is not used at the moment. This can, for instance, be during nights, weekends and evenings. The controller stands by to change...

Change-over function RC-C3DOC… has an input for change-over that automatically resets output UO1 to operate with heating or cooling function. The input can be connected to sensors of type PT1000, with the sensor mounted so that it senses the temperature of the coil supply pipe. As long as the heating valve is more than 20 % open, or each time a valve exercise takes place, the difference between the media and room temperature is calculated. The control mode is then changed based on the temperature difference. Optionally, a potential-free contact can be used. When the contact is open, the controller...
