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 LPV2 Door Switch Kit is for LPV2 Heated Units. It includes a surface mounted plastic door switch (99-018), a unit mounted time delay (INS-TD) and a unit mounted 24V controller (INS-24V). 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.
