“When using the Halo LED on a newer HVAC unit utilizing a variable speed fan or ramping motor with constant on 24-volt control, it is recommended the enclosed relay or similar (24VAC coil, SPDT) be used in order to turn off the power to the HALO LED when the HVAC unit is turned on and off. Unlike the standard Halo, the longest life for the LED Halo is achieved with it cycling on and off as needed.

Note: This is only a recommended installation for the control relay, all wiring must be done to comply with all pertinent local codes and regulations. To avoid injury or shock hazard, ensure power is disconnected from the HVAC unit prior to any electrical work being performed.”

Notice to Installer: This unit must be wired in series with the blower to cycle on/off with the blower. This installation is required in order to be in compliance with new safety standards and to ensure maximum energy efficiency and LED module service life.
