Description
The AC-SOS Energy-Saving Shut-Off Switch uses a wireless magnetic transmitter to detect when a door or window is opened. If the opening remains for more than 2 minutes, the system automatically turns off HVAC operation. Once the door or window is closed, the HVAC system resumes normal function. This wireless solution helps prevent compressor short cycling, lowers energy bills, and reduces unnecessary maintenance.
Important: This transmitter MUST be used with AC-SOS systems. It cannot operate without the AC-SOS control module.
