A door switch makes using your air curtain easy and efficient. By adding a door switch, your air curtain can turn on and off automatically when your door opens and closes.
The Door Switch Kit is for STD2, Phantom and HV2 Heated Units. It includes a metal, surface mounted door switch (99-125), and a unit mounted time delay (INS-TD). The INS-TD is an adjustable time delay that will keep your unit running for a configurable period of time, ranging from as little as 1 second up to 17 minutes.
Total Home Supply suggests that a switch is purchased with all air curtains.
