When using the HALO-LED on an HVAC unit utilizing a variable speed fan or ramping motor with communicating thermostats, the RGF Air Sensing Switch Kit (HLED-AS) or equivalent may be used. The HALO-LED is designed to power on and off with the blower of the HVAC. Unlike the REME HALO®, the HALO-LED has a longer life with the power cycling on and off as needed. In order to tie the incoming power of the HALO-LED with the HVAC blower power, an air sensing switch may be used.
