System architecture
Refrigeration & HVAC Control system architecture
The controller coordinates temperature or humidity measurement with compressor, heating, defrost, fan, alarm or auxiliary functions. Output count alone is not sufficient for selection; sensor version, control sequence, electrical ratings, supply and communication options must also match the refrigeration or HVAC design.
