Route probe cables away from high-voltage electrical lines (compressor, heaters, mains supply) to avoid electromagnetic noise interference.
The is a high-performance, microprocessor-based controller widely used in commercial refrigeration and HVAC systems. Known for its reliability and precision, this "Switching" series controller is designed to manage temperature-controlled units with efficiency.
Electronic controllers for centralised air-conditioning units : Deep configuration of digital and analogue outputs
Programming an Eliwell controller often feels like cracking a code if you don't know the button sequence. Here is the standard procedure for the Energy Flex series:
Press and hold the key for more than 5 seconds until the first parameter code appears on the display.
According to the SB655 technical data sheet , the controller is engineered for complex HVAC/R environments:
Solution: Inspect the evaporator probe wiring. If Probe 2 fails, defrost cycles will typically terminate based on the backup timer () parameter rather than temperature ( dSt ). "AH1" — High Temperature Alarm
