Delta 125 Numeric Chronoproportional Temperature Regulator
Complete installation and operation manual for the Delta 125, a numeric temperature regulation control unit designed for external electric heating systems. This modular device features 8 modules of 17.5mm width and operates on 220V AC power with a maximum consumption of 7VA. The unit supports simple and double heating configurations with optional temperature limiting. Technical specifications include a 5A, 220V inverse polarity output relay, external sensor and limiter with 1000 ohms resistance at 25°C, and operating temperature range from 5 to 40°C. The manual covers installation procedures for external sensors, control unit mounting on DIN rail, wiring connections, and detailed configuration settings. It includes programmable parameters for day and night setpoints, limiting thresholds, temperature offset values, and timing base configuration. The device provides visual feedback through electroluminescent diodes and seven-segment LED displays showing external temperature, limit temperature, calculated percentage, and various operational modes.
