This manual introduces the features and characteristics of CAREL temperature and humidity sensors (AS series), including different types, codes and accessories, installation methods, technical parameters, etc.
The Carel AS series includes active temperature and humidity probes for heating, cooling and air‑conditioning systems. Variants cover duct, wall‑mount, outdoor, immersion and general‑purpose applications, with options for voltage or current output and compatibility with Carel controllers.
The manual provides general characteristics, part codes, installation instructions, wiring diagrams for various controller families, technical parameters, dimensions and safety warnings. It also details power requirements, output ranges, protection ratings and recommended cabling for reliable operation. This manual is written in Chinese.
| Power supply (DC) | 9‑30 VDC |
|---|---|
| Power supply (AC) | 12‑24 VAC |
| Temperature measurement range | -10 °C to 70 °C |
| Humidity measurement range | 0 % rH to 100 % rH |
| Output signal | 0‑1 Vdc or 4‑20 mA (active) |
| Protection rating (housing) | IP55 |
The sensors can be powered from 12‑24 VAC or from 9‑30 VDC.
The current‑output can be transmitted up to 100 m without loss of accuracy.
Use multi‑core shielded cable with a maximum outer sheath diameter of 8 mm.
For PT1000 active sensors the accuracy is ±0.2 °C at 25 °C.
