RTN400 - RTN400 SM - RTN600 series
Controllers for plug-in counters
Applications
RTN400 are compact controllers for plug-in and remote cabinets with thermostatic valve control.
RTN400 controllers are compact and stand out for the high-performance and high flexibility they offer through energy-saving algorithms and the direct control of compressor and fans.
RTN400 SM provides energy savings in supermarkets and commercial food distribution and storage applications; it is suitable for the control of EMBRACO VNEU and SECOP CCD variable speed compressors, obtaining maximum performance through a control algorithm with self-learning of operating parameters. It also combines optimised defrost cycle management, dewpoint-based heating and anti-condensation element modulation and cold room set point modulation, with automatic identification of open/closed operational time bands.
RTN400 SM controllers can be interfaced with KDEPlus , KDWPlus and KDT keyboards and with the ECPlus display module.
RTN600 have energy-saving functions for use in supermarkets and commercial food distribution and storage applications. RTN600 combine optimised defrost cycle management, dewpoint-based heating and anti-condensation element modulation and cold room set point modulation, with automatic identification of open/closed operational time bands.
Configuration has been simplified by introducing pre-set profiles for 8 separate applications that can be easily selected through the KDEPlus , KDWPlus and KDT user terminals.
The remote ECPlus display can be used to view displayed date from up to 100m away, differentiating it from the data displayed on KDEPlus , KDWPlus and KDT terminals.
- Single or dual compressor control
- Advanced resistance defrost
- Evaporator fan control in Night&Day mode
- Fixed duty-cycle frame heater control
- Pre-programmed, easy-to-select configurations.
- Adaptive control for variable speed compressors

Application examples RTN 400
In a plug-in counter, RTN400 is used to control compressor, lights and fans connected to a monitoring system via RS-485 network (the optional board is needed for RS-485 connectivity).
Plug-in R290 tank with variable speed compressor RTN 400
RTN 400 SM can control all aspects of the application, including compressor, fans, lights and defrosting. The innovative self-learning algorithm for control of variable speed compressors significantly reduces the time required for commissioning, ensuring maximum energy efficiency in all conditions and a longer motor life.
The advantages of this type of application are:
- Smaller compressor
- Reduced refrigerant charge
- Continuous control of cooling capacity
- Fewer compressor start-ups and consequently longer compressor life
Application examples RTN 600
RTN600 can be used for different applications. In a plug-in counter, for example, RTN600 are used to control compressor, lights and fan connected to the monitoring system via RS-485 network. With RTN600 you need the optional RS-485 connectivity board.
