Regin RC-C3DOC Room Controller Pre-Programmed System

Regin RC-C3DOC Regio Midi is a complete pre-programmed room controller with a backlit display and RS485 communication designed to regulate heating, cooling and CO2 in a zone control system. It ships pre-programmed and can be configured via Regio Tool PC software for quick deployment, and it supports 24 VAC input (18–30 V AC, 50/60 Hz) with a power draw of about 2.5 VA. The unit communicates on RS485 using Modbus, BACnet or EXOline for system integration, and it can drive 0–10 V DC actuators and/or 24 V AC actuators or On/Off actuators with spring return. Built-in is a room temperature sensor; external PT1000 inputs can be used for room, change-over, or supply-air temperature limitation; there are inputs for occupancy detectors, window contacts, condensation sensors, and an external CO2 sensor. The RC-C3DOC offers three universal outputs (UO) at 24 V AC/1 A and one analog output (AO) at 0–10 V/5 mA, with digital inputs including AI (PT1000, 0–50°C, 0–10 V), UI (PT1000/DI), DI, and DI/CI; the device’s ambient operating range is 0–50°C with IP20 protection, and its compact 95 × 95 × 31 mm PC housing weighs about 0.11 kg. It supports a setpoint range of 10–50°C and is designed for wall mounting or installation on a wiring bottom plate that simplifies wiring and commissioning. Applications include regulating in office, school, retail and healthcare environments where precise temperature, airflow and CO2 control are required.
