The Illumra Wireless HVAC Setback Module (Door Contact Receiver) enables automated energy savings by controlling HVAC systems and other low-voltage loads based on door or window activity. Designed for Illumra’s 902 MHz wireless platform, this module links to self-powered wireless switches or window/door sensors to trigger setbacks when spaces are unoccupied—without batteries or new wiring.

Ideal for commercial buildings, hospitality, and energy management applications, the HVAC setback module features a latching relay output, long wireless range, and simple push-button commissioning. Its compact design allows for flexible mounting inside or outside junction boxes, while state memory ensures reliable operation after power loss. By integrating wireless door sensors with HVAC control, this module helps reduce energy waste and improve building efficiency with fast, maintenance-free installation.
