DEI-711 is typically a mechanical temperature thermostat/temperature controller used in refrigeration and HVAC systems (e.g., fan-coils, coolers, freezers). It works by sensing temperature via a capillary tube + bulb and switching electrical contacts for control outputs such as compressor, fan, or valve relays.
Typical Features
Application: Refrigeration or HVAC temperature control (cold/heat).
Temperature Range: Cold ~16 °C–30 °C and Heat ~16 °C–32 °C (example spec) — varies by version.
Relay Outputs (example):
Compressor relay ~25 A @ 250 VAC
Fan speed relay ~3 A @ 250 VAC
4-way valve relay ~3 A @ 250 VAC
Supply: 110–220 V AC (often selectable).
Control type: On/off (mechanical sensing, capillary/thermal element)
