Recommended Posts

had a new water temp sensor installed. it goes from the filter inlet to the

intellitouch panel. it takes a Very long time for my system to get anywhere

close the the correct temperature, could be many hours.

Questions :

* how long should it take from the time the filter turns on in the morning till i have a reasonably

accurate water temp reading ?

* which is the correct water temp thermister for the intellitouch system 5i ?? Is it the 520272 or

520572 ? what is the difference between the two ??

* does my issue sound like a bad thermister ?

thanks,

walter

follow up on the questions above:

* what % of the sensor body needs to be wet to get a reasonable reading ?

* does the sensor tip need to be wet ?

* i've noticed that my sensor is not installed at the top of the pipe ? the hole

is drilled mid way down the pipe such that the sensor goes side to side and

not top to bottom (i did not install the sensor). i assume this is part of my problem ?

thanks,

walter

The sensor should be accurate within 5 min. if not sooner.

The 520272 is a sensor with a 20 cord. I don't recognize the other number. Another Pentair sensor is a TS5L used with the Compool systems, you don't want that one. It has green and red wires. The one you should have has red and black wires.

Usually, when the sensor goes bad, it is way off. Take the sensor out and look at it. It may have a crack, or it may look like it had burst, or it may look OK.

As long as the pipe is always full of water by the pump, there shouldn't be a problem with it mounted like that.

Well I've tried several sensors now including the Pentair 520272. Still not working properly (= temp off

by 30 to 40 degrees). Could it be that the control board that it wires into is bad ?? (the screw down post

socket does seem a little loose). Any one have a good parts source for this Intellitouch control system ??

thanks,

wk
