Do you need to purchase 3 separate ones for different levels in a house?

Our house has an unfinished basement plus two above-ground floors. We have one heating system and one thermostat. I placed the low temperature alarm on the first floor of our home, not far from our thermostat. Our basement is normally colder than the finished parts of the house, which is why I located the low temperature alarm on the first floor (to avoid false alarms).

I have one installed in my upper level. I did have a freeze issue in the basement which stopped my heat. The alarm did go off and call but I wish I would have had one in the lower level to prevent some damage. If you find an answer please let me know as I too am considering having two on the same phone line. Will that work?

No. It will monitor the overall temperature of the house and call if it is below. In the case where the levels have no access to the level with the unit, it might make sense to have 2. I have three levels and my unit is on the first floor. A basement and bedrooms are easily monitored.

if you have three heating zones, yes you will need three alarms, if only one thermostat in house then put one alarm on coldest floor

Yes. I don't know of a way to hook up more than one sensor. Works well though.

If all 3 levels are heated by the same furnace one unit should do the trick. Just put the sensor in the zone that receives the least heat. However, if each level is served by its own furnace you will need 3 units.

All three levels must be assembled for use. As Echo said, it would be a nice option.

Yes they do so you can have them in separate areas or different rooms if you like.

No. You pick the one you want and order it. You have to buy all four separately.

You can either purchase one unit by itself for a certain price or purchase a 2 count which will represent two of these units or you can purchase four of the units. The size of unit does not change just the number of these that you wish to purchase for different areas of your home. I hope this helps!

no.. you will have to buy those separately. but those will not be too costly.

No, I asked the manufacturer about this and was informed that they must be purchased separately. Currently I just have some pieces of cardboard in them, which seem to be working ok as a temporary solution.

you need as many as you have rooms with doors. If you have an open area that doesn't have walls or doors, you only need one there. I put one in every bedroom, bathroom, 1 in my living/family room and 1 in my kitchen for a total of 6.

It would be best to purchase one for each door so you have independent control of each door. They work great. Mine triggers a welcome home scene if it is after dark.

Yes, you can choose to use only 3, you can also choose to arrange it any way you please, not just in ascending or descending order.

If u do u wanna make sure that they are in separate boxes. Unless the ratings on each sub match up. Cause one can over power the other one and cause cancellation of the base.

Yes you would need to purchase two, we put our one in a large corner and it gives our baby girl more playroom! :)

No. You can buy an additional piece so they don't all 4 have to be wired to the unit though. Either way I wouldn't recommend this model.

Absolutely. In fact, that's the exact reason why we purchased the item. The difference between the floor and the bottom of the tub actually required us to buy two of the steps.

I would say get two, one for upstairs and one for the first floor. Other than that they work great.

You need only one, they sell the one or French door type. The one I bought was for French door type.

Since these units can function separately, we split them around the kitchen where needed. Three different sections of lighting. Just install the other areas as separate. Worked well for us since on separate switches.
