Hot Tub Thermometer

[barshnik]

I've had it a couple of years now, and don't remember which web site I bought it from.  Mine does not hook to the internet, although they did have (more expensive) ones that did.  By now I'm sure ones similar to it do for the same price I paid for mine back then.  It came with 1 remote, I purchased 2 more.  Just do a search 'weather station' and you'll have plenty to look at.  Or, look at the LaCrosse web site for a start.

Oh, the high / low temp alarms, they only work for ONE remote sensor.  I decided that my wine cooler was more important to get blared at if temps get out of whack  than the spa, so I chose that one.

I've got more $ invested in wine than the spa (even though that is just south of 7k), so I want to know if somethling goes haywire with it...

I hear ya!  No wine cellar here so the min/max alarm would be for spa.  From the pics I found your unit (Lacrosse WS-9119U).  The one remote that comes with it doesn't have a probe but could be used outside, etc.:

The remote for the spa would need to be purchased...the one with the wire probe sensor (Lacrosse TX3UP):

I may buy it here:  http://www.ambientweather.com/lacrtewsinwi.html

One more question.  A couple of websites recommend AA and AAA Lithium batteries rather than plain Alkaline.  It says it helps especially with outside remotes.  Do you use the Lithium variety?

Thanks for the info,

Marc

<<Do you use the Lithium variety? >>

Lithiums hold voltage under very cold conditions much better than alkilines.  I've always used regular alkilines here in LV - if I was back in North Dakota, I'm sure I'd use lithiums, though, at least in the winter...

Remember, only channel 1 is programmable for alarms on high or low temps, so if you have 2 or 3 remote sensors, you should put the batteries in your spa sensor first, then the others.  I had to mess around a bit to get my wine cooler sensor to be recognized as channel 1.

I'll check out your link, and see how much cheaper it is now...

Barshnik,

We are in Northern NJ and in the winter low temps can get down to zero so I will use the lithium inn the outdoor remotes.  Since the inside unit is indoors no reason to splurge on the lithiums unless it would help in the wireless reception, which I don't think it would.  One final question...how do you keep the thermocouple from floating up to the surface of the tub?  Or does that even matter?

Thanks again,

Marc

Use regular alkalines for the base unit.  The wired thermocouple has just enough weight to sink to whatever level the wire allows it to with no pumps on.  Since I just stick it in a filter well, with the pumps on there is a downward flow that keeps it down, although I doubt if it matters much.

Since the base unit sits on my bedstand, it's kind of nice to be able to check the spa temp when I wake up before even getting up (and jumping in.)

I'm kind of a weather junkie, so the spa and wine monitoring were sort of a bonus - the barometric graphing is really cool, and is a really good indicator of coming changes.  Right now it reads 102.1, perfect, so I'm getting in with a glass of Babich Sauv Blanc ($11.99 at Costco by the way, and a nice 'summer' wine) and going to bed...

Just checked, now much cheaper than when I bought.  I forgot, what I find most interesting with both the spa and wine readings are the min/max (resetable) so you can see how much variation there is from period to period - to the day and time when the low and the high were reached, and what they were.

High variations of spa temp not explainable by outside temp/wind/useage could be an indicator of a failing heater unit, so this is useful information to have...  I just checked the min/max of my wine cooler - today the min was 54.4 and the max was 54.9 - pretty good regulation.  But then, I didn't have the door open today, drank the wine from Costco.

The spa varied from 100.1 (8:09 am.) to 102.8 (8:20 pm.), but I was in and out of it a few times, and I have the control set to only heat between 4pm and 9pm (even though the circ pump runs continously.)  The spa is set to 102, so again, good regulation and insulation is indicated (max daytime outdoor temp reached 83 at 4:01 pm.)

Update:  Still works like it should.  It stays in the water & gets knocked around & throughly soaked when tub is running.  Still no issues.  Have not added silicone to the screws & am thinking "if it ain't broke....."

Mine cr*pped out this morning.  3+ weeks.  I am NOT amused.   :-[

Slight thread hijack - my current floating (ducky) thermometer keeps ending up in the filter well.  Any issue with him or this wireless until living in there?  I don't want to screw up my filtration.

I've had the same floating ducky spa thermometer (sans the ducky) in my filter well of my Prodigy for over ten years.  It still works fine and has never caused a problem hidden back in there.  Its the SPA version that goes up to 120 degrees, rather than a pool one that only goes up to about 110.  I agree the pool thermometers are hard to read that far up the scale.

I've found another, less expensive solution for those that are interested.

People seem to have had good luck with LaCrosse Technology wireless systems.  They are expensive though.  I found a much less expense LaCrosse model that seems to do the trick.

Look at the LaCrosse WS-9029U-IT.  It is $29.95, monitors indoor temp and humidity, outdoor temp wirelessly, and includes a probe for the tub!  http://www.lacrossetechnology.com/9029/

I ordered one from Wind & Weather and installed it this afternoon.  Works great.  I just ran the wire probe into my filter compartment.  It is very thin so no issue with the cover.
