Programmable Controls
The ir33 series is designed to address complex refrigeration and air conditioning applications. The series is made up of electronic microprocessor controllers with green or blue LED displays and graphic symbols to assist the user. The ir33 series is designed specifically for the management of reach-in and walk-in coolers as well as condensing units..
- range: numerous models are available with 1 to 5 outputs along with 2 configurable digital inputs and 2 probes
- flexibility: various voltage options including 24 Vac, 110 Vac and 230 Vac for panel or DIN mounting installations
- serial connection: communication available for RS485 network or CAREL plantVisor supervisory system
- certification: ISO 9001 certified design and production, as well as CE, UL and NSF listing
Available ir33 features include:
- infrared remote control that can be used to change setpoints and modify controller operation
- programming key for quick controller configuration
- remote LED display for remote temperature indication
- high efficiency LED display
- HACCP functionality to assist with your HACCP plan
- RTC (real time clock) for accurate management of defrost and alarms
