For optimal cooling efficiency and system longevity, pay close attention to these vital parameters:
uses a folder-based menu structure. Standard access typically involves:
: Built-in control for fans/pumps (up to 2A) without external devices. Electric Automation Network Technical Specifications Inputs/Outputs
This is where the SB655/C excels. It supports several defrost types: Turns on a heater. Reverses the cycle. Timed/Natural: Simply stops the compressor. Termination: Ends defrost based on time or evaporator temperature. Common Error Codes Air probe failure. Evaporator probe failure. High-temperature alarm. Low-temperature alarm.

: Native support for Modbus and Televis protocols.
The SB655C controller is designed for energy flexibility. Through careful use of inputs and configuration, you can implement , where the system reduces its power consumption when an external signal (like a utility peak pricing signal) is received. Economy modes can also be configured to run the system at different setpoints based on occupancy or time of day, as managed via the digital inputs.

The controller will display alarm codes related to sensor failures, low/high pressure, or compressor overloads.
If you need help identifying which parameter controls a specific alarm, or if you are looking for the Modbus register map, let me know!
Modern facilities benefit from centralized monitoring and control. The SB655C can connect to a network via its serial port using standard protocols like Modbus or Televis . This allows a central computer or building management system to read all parameters, view live temperatures, change setpoints, and acknowledge alarms for every connected controller from a single location. It supports several defrost types: Turns on a heater
Must be powered using an external transformer that perfectly matches the technical voltage requirements specified on the product ID plate.
Proper installation is the foundation of a reliable system. Rushing this step can lead to erratic behavior, sensor errors, or even equipment damage.
