The Carel RITCUSRG02 is a microprocessor-based electronic controller designed specifically for heating and cooling applications. Part of a series developed to replace or enhance the IR32 Universal range, this "plug-in" relay controller offers a simplified user interface with high precision for temperature management.
Below is a guide to its primary functions, installation requirements, and programming steps based on official Carel documentation. 1. Key Specifications & Capabilities
The RITCUSRG02 is built for versatility in industrial refrigeration and climate control systems.
Temperature Range: Monitors and controls temperatures from -50 °C to +150 °C.
Input Types: Supports standard Carel NTC (10 kΩ at 25 °C) and PTC (985 Ω at 25 °C) probes.
Output Configuration: Typically features two control zones (relay outputs) for managing multiple regulation stages, such as a compressor and an alarm or a heater and a fan.
Protection: Front panel protection is rated up to IP55, making it suitable for environments with moderate moisture. 2. Installation Best Practices
Correct installation is critical to prevent electromagnetic interference and hardware failure.
Wiring Separation: Always separate probe and digital input cables from high-power inductive load cables. Never run signal and power lines through the same conduit.
Probe Placement: Avoid installing probe cables near contactors or circuit breakers. If extension is needed, use cables with a minimum cross-section of 0.5 mm².
Environment: Store and operate the device within the specified temperature and humidity limits to prevent internal condensation or damage to plastic components. 3. User Interface & Basic Operation
The controller features a bright 3-digit LED display and a simple keypad for adjustments.
Viewing Temperature: By default, the display shows the temperature from the primary probe (B1). Changing the Set Point: Press the SET button briefly. Use the UP and DOWN arrows to adjust the desired value. Press SET again to confirm and save.
Status Icons: If the compressor or fan icons are blinking, it typically indicates a delay (e.g., minimum off-time) is active before the device will start. 4. Programming Parameters
The RITCUSRG02 uses two levels of parameters: Type F (frequent) and Type C (configuration/password-protected). Accessing Parameters: Press SET for more than 3–5 seconds to enter the menu. carel ritcusrg02 manual
If prompted for a password (PS), the default is typically 22 for configuration access.
Saving Changes: After modifying values with the arrows, you must press SET for at least 3 seconds to definitively save the new settings. If no button is pressed for 60 seconds, the device will exit without saving (timeout). Installation manual - Tempatron

Carel RITCUSRG02 is a specialized pressure sensor controller. While specific technical manuals for this exact part number can be niche, it belongs to Carel's ecosystem of high-precision electronic controllers. CAREL control A primary feature of the Carel RITCUSRG02 global compatibility and precision , as it is designed to work as a dedicated Pressure Sensor Controller within industrial cooling and HVAC systems. WiAutomation Key Features of Carel Controllers
Based on the general architecture of Carel sensor controllers, you can typically expect: Precision Monitoring
: Real-time management and interpretation of pressure data to ensure stable operation of chillers, heat pumps, or cold rooms. Secure Configuration
: Access to parameters is usually protected by a standard password (often
in many Carel series) to prevent unauthorized changes to critical settings. Serial Interface Ready
: Many models are designed for integration with RS485 serial supervisor systems for remote monitoring. Alarm Management
: Dedicated logic to trigger alerts if pressure levels deviate from the safe operating range. CAREL Industries
If you need to adjust specific settings, many users find that holding the button allows for quick setpoint changes, while holding together typically opens the deeper parameter menu. CAREL RITC – part of the RITC series

The Carel RITCUSRG02 is a microprocessor-based electronic controller designed for heating and cooling applications. It is part of a family of plug-in relays that provide a simple, cost-effective solution for temperature regulation in refrigeration and HVAC systems, building on the technology of the IR32 Universal series. Technical Specifications
The RITCUSRG02 is engineered for versatility and precision in climate management. Temperature Range: Measures and regulates from -50negative 50
Regulation Zones: Features 2 independent regulation zones, allowing for a "double thermostat" function.
Inputs: Supports analog NTC or PTC probes and includes one digital input.
Outputs: Relay-based outputs for controlling heating or cooling stages.
Protection: Front panel protection rated up to IP55, depending on the specific version.
Display: High-efficiency red LED digital display for temperature and status monitoring. Key Features & Operation
The controller offers several advanced features for professional HVAC management:
User Interface: Equipped with an ergonomic three-button keypad for easy navigation and setting adjustments.
Dual Setpoints: Can manage two independent setpoints using two control probes and two relays.
Security: Includes keyboard locking and password protection for parameter security.
Connectivity: Supports RS485 for integration into supervisory systems and uses the IROPZKEY for rapid parameter copying. Installation & Wiring Guidelines To find the correct manual:
Correct installation is critical to prevent electromagnetic interference and ensure device longevity.
Cable Separation: Keep probe and digital input cables separate from power and inductive load cables (e.g., motor or compressor power lines) to avoid signal disturbance.
Environment: Avoid installing in excessively hot or humid environments. High temperatures can damage plastic parts and electronic circuits. Wiring:
Probes: Use terminals 5 and 6 for the primary temperature probe. Digital Input: Connected via terminals 6 and 7.
Relays: Control outputs are generally connected through terminals 1 through 4.
Mounting: The "TOP" versions feature an innovative front-panel mounting system using two screws for easier integration. Programming & Maintenance
Users can customize the parameter list to show "frequently used" or "password-protected" settings.
Rapid Programming: Settings can be uploaded quickly using a hardware key even when the device is not powered (on TOP versions).
Cleaning: Never use corrosive chemicals or aggressive solvents. Use only mild detergents to clean the plastic housing.
Safety: Only qualified personnel should perform technical interventions, and the machine must be disconnected from the mains power before accessing internal parts.

The Ritcus RG02 is a Carel refrigeration controller family (specialised control for refrigeration/cold rooms). Official user and service manuals provide: features, terminals/wiring diagrams, probe types and wiring, digital inputs, configurable outputs (compressor, fan, defrost, auxiliary), display/terminal operation (PGD/PST), parameters list, programming steps, default settings, alarm codes and troubleshooting, installation/environmental notes, and safety/disposal instructions.
This is the heart of the RITCUSRG02 manual. Carel controllers organize settings into a "Map." You will typically see parameters labeled with codes like:
Cn (Configuration): These set the type of control (On/Off, Modulating, PID). This is the first place you look if the unit isn't reacting to demand.St (Status): Read-only values showing current humidity, temperature, and voltage.Al (Alarms): The history log of faults.Pro Tip: The manual contains a "Parameter Map" table. Use the "Search" function (Ctrl+F) in your PDF viewer to find specific codes quickly rather than scrolling through pages of tables.
The Carel RITCUSRG02 manual isn't just a "how-to" guide; it is the blueprint for your system's intelligence. Many technicians attempt to "figure it out" on the fly, but Carel systems are sophisticated. Without the manual, you risk:
