DUCT HUMIDITY SENSOR / SWITCH ATTENTION Do not exceed the maximum power supply rating! Measure before installation! Unregulated 24 VAC supply units provide higher nominal output voltage and activate the integrated fuse protection. ATTENTION If a G‑type article is using the same AC power supply source (transformer) as F‑type article, a SHORT CIRCUIT may result when the power supply and analogue signal terminals are connected to the same common ground! In this case always connect different article types to separate AC transformers or use the same... -
