ActronAir LM-Series Remote Air Sensor provides a separate temperature sensing point for LM-Series wall controllers on Classic Series and ESP Plus residential ducted systems, mounting remotely from the wall controller to sense room temperature in the optimal location for accurate zone comfort control. The LM-RAS is an alternative to the LM-RS terminal-block variant, using a plug connector for compatibility with specific indoor unit configurations. Low voltage inputs only -- connecting 240VAC will damage equipment.
