Ageon’s A106 is a digital temperature controller from the brand’s Black Line designed for refrigeration applications such as freezer display cases and cold rooms. It uses two NTC temperature sensors (ambient and evaporator) and provides three relay outputs to manage the compressor, forced defrost (electric heaters or hot gas) and fan operation. The measurement range is −50 to +100 °C with 0.1 °C resolution. A digital input supports a door-open sensor. The unit is dual‑voltage (110 or 220 Vac), with front panel IP65 and sensor IP68 protection, and installs in a 70 × 29 mm panel cutout. Functions include eco mode, thermometer mode, alarms, data logging and standby. RS‑485 enables integration with Ageon’s WebFi/Arcsys monitoring for remote supervision.
