Ageon’s A103 PID-U is a panel‑mount environment controller for precise temperature and humidity regulation. It uses a single combined sensor for air temperature and relative humidity and provides three outputs: a TRIAC output with PID control for heating, a relay output for humidification or dehumidification, and an auxiliary relay configurable as a cyclical timer or for refrigeration. The unit is dual‑voltage (110/220 Vac), has an IP65 front panel, and supports quick setup with the FastKey programming key. Remote monitoring and alerts are available via the WebFi system. Measurement ranges are −20 to +80 °C for temperature and 10 to 90% RH for humidity, making it suitable for HVAC, agriculture, storage areas, and incubators that require stable heat and moisture control.
