The DEI-625E is a digital temperature controller / thermostat with a built-in thermometer and a sensor probe, designed for monitoring and controlling temperature — typically in refrigeration, coolers, chillers, freezers or similar equipment.
Key Features
~Temperature range: approximately -40 °C to +40 °C (varies slightly by vendor) with about ±1 °C accuracy.
~Sensor: One NTC temperature probe (usually ~1.5 m long).
Outputs:
~Compressor control output — relay rated around 25 A at 250 VAC.
~Auxiliary outputs (e.g., lighting, power) — rated ~10 A at 250 VAC.
~Power: Typical supply around AC 100–240 V (some setups use 12 V transformer to controller input).
~Display & controls: Digital display with buttons to set temperature setpoints, differentials, and potentially defrost/period parameters (see manual).
Typical Uses
~Refrigeration temperature control (coolers, freezers, chillers)
~Small HVAC or environmental monitoring systems
~Fridge or cold-room control setups
