Product Description:
The ERC 112C is an electronic refrigeration controller manufactured by Danfoss for the Electronic Climate Controllers series. It is intended for chilled display cases, walk-in coolers, and small cold rooms where automatic temperature regulation, compressor protection, and timed defrost cycles are required. By combining sensor processing, control logic, and output relays in a compact DIN rail package, the device simplifies panel layouts and provides a digital alternative to traditional electromechanical thermostats. Its integrated design reduces the number of separate control components required inside a refrigeration panel while supporting consistent temperature management across common commercial cooling applications.
The controller accepts four analog inputs, allowing temperature probes, pressure sensors, or other compatible analog devices to be monitored simultaneously. A separate digital input is available for a case-light switch, door contact, or external alarm contact. Actuation capacity is provided by four digital outputs that can control a compressor contactor, evaporator fan, defrost heater, and auxiliary load. The power section supports a supply as low as 100 VAC, enabling stable operation under low-line conditions. Its upper supply limit of 240 VAC accommodates standard single-phase electrical service in many regions. This broad input range reduces the need for an external transformer when the controller is installed within a compatible refrigeration system.
Frequency compatibility covers 50/60 Hz, allowing the timing functions to operate with either common utility frequency. Operating information is presented on a blue backlit segment display that remains easy to read in dim equipment areas and low-temperature environments. The display gives users direct access to temperature values, operating status, alarms, and configuration menus without requiring a separate interface. The unit weighs only 0.077 kg, which limits the load placed on lightweight panels and enclosure doors. Its low mass and compact housing also make it suitable for condensing-unit compartments and refrigerated cases where available mounting space is restricted.
