Description
Digital programmable single-sensor temperature regulator-controller Whicepart EL 961 (replacement ELIWELL ID 961) for refrigeration units.
Designed for ventilated refrigeration systems with low/medium temperatures (-45 to +10°C), refrigeration chambers, displays, and freezer cabinets. It features an input for a temperature sensor, either RTD or NTC (selected by parameter), and also includes a TTL port for using a copying card for swift device programming. Defrost cycle duration can be determined based on programmed time intervals as well as by the sensor reaching a defined value on the evaporator. The sensor's reading is displayed on a 3-digit display (with a minus sign). Temperature adjustment within the device ranges from -50 to +110°C.
