How does it turn on and off? Does the UV light senses air flow and then turns on? or does it stay on

It is designed to stay on. I thought about wiring it to the fan control, but I'm not sure if the repeated turning on and off wouldn't shorten the life of the lamp. It's designed to be replaced every year.

It will only turn on when a mounting screw makes contact in the housing, implying the unit is safely mounted. If that screw is not pushing the contact sensor, device will not turn on. The theory is if it's mounted inside the duct, then and only then will the light come on, securing no light to your eyes.

In my Carrier High efficiency heating system, there is an external duplex outlet located near the cold air return duct where I installed the UV Lamp. this outlet is hot when the air circulation fan is on, and off when the fan is off. So, my lamp comes on anytime the air in the system is circulating regardless of whether the system is set for heating (winter) or cooling (summer).

It does not have an on/off switch. It stays on all the time to contnue to kill bacteria in the ductwork and in the conditioned air. The bulb should be replaced once a year and wiped down every other month.

This just plugs in and stays on. Some people wire a relay to the cool control wire (reversing solenoid) to power it on in the cool mode only. It is not needed when heating. Or you can simply un-plug it when you don't need it. The bulbs are recommended to be replaced annually because they make more money that way. They last longer if not used full time. Replacements are only $12.90 from Lampline Lighting Inc. Order TUV PL-L 18W/4P and save 50% over everyone else.

Ispring has a switch when water is called for the UV light turns on when its not calling for water it stays off this is good because you won't have a light on all day. this is the part very reasonably priced. iSpring 123Filter UVT11A - 11-Watts 110-Volt Transformer Ballast with Smart Flow Sensor Switch

It turns on and off automatically. Getting it set to exactly the right temperature may take some fiddling around with it, but once it's set it stays.

The fan is not connected to the house thermostat and does not have its own thermostat. It turns on when solar panel recievies enough sunlight and turns off when sunlight disappears. No on/off switch, simply works with the sun. On a cloudy day, fan may not turn on

It turns on when the supply side temp is higher that the out side / room temp by the setting you make on the unit.( in heat mode ,opposite in cold mode ) then turns off.Had mine for over a year and still works great. I have a 2 story home and use it to draw hot air to a distant down stars room. Some times will draw hot air from upstairs down when the heater is not on. kind of balances the whole home temp.

The unit has a cord cap that twist onto the flange bulb connector on the duct work, the other end just plugs into a 120v outlet. Around the clear flange lamp connector, when the unit has power you will see a blue ring. You will be able to see that the bulb is on. Please do not look at the uv bulb in side the duct work when its on!!

Fan and light is all one button, so no, they are on together. The fan is not real strong. But this doesn't matter to me, Im real happy with this brand of a uv light.

Yes. But if you set it near the ambient temperature it will come on for a couple seconds then go off. Techs told me that is how it senses whether it needs to come on or not.

On the side of the unit, near the top, there is a small grey pullout flap. Underneath that there is a switch to turn the UV bulb on and off

It turns on by a thermostat that you set. When the warm air hits the unit the fans kick on.

It is Ultraviolet light, which humans can't see, so during the day it is very hard to see if it is on or off, but at night you should be able to see it. If at night the whole bulb is glowing then it is working, if only the top is glowing there is a problem.

Hello, I bought two of these units. They work great but the light is a little bright while sleeping. Fortunately there is a button on the top of the unit that turns the UV light off. Hope this was helpful.

If you take the back cover off and pull the filter. Then turn the UV light on and off with the remote while looking in the cavity you will see the light go on and off. If you don't then the bulb is not working.

Yes it turns the light on/off plus dim if you hold the light button down. It has three speeds on the fan. Great fan, quiet and moves a lot of air.

The light comes on when the door is open. The light will stay on all night if you forget to close the door. It is on when the unit is running.

I bought my UV light separate from the 5 stage system I had. I unplug the UV light when not in use. They should make it so the light only comes on when the RO system is working. Yes, the light is on all the time if you don't unplug it.

There is an on and off switch with 2 options. Cool air or Warm air. I leave it on during my nail service and I have the customer rotate their hands in and out like if I were doing a gel service.
