The HVAC Smart Relay Switch (HSRS) is an energy saving device designed to automatically shut off air conditioning or heating when a monitored door or window remains open for a preset period of time. Available in both wired & wireless packages, the system uses compatible door/window sensors (two included). The HSRS is fully configurable using onboard DIP switches, allowing you to establish specific operational parameters. For instance, configure the device to temporarily disable the air conditioning or heating system when any door or window has remained open for 10 minutes and then re-enable when the door has remained closed for 1 minute. (Requires installation by a qualified hvac technician or electrician.)
