Temp sensor a little short
Temp sensor a little short
is there anyway to extent the sensor? trying to get the controller away from under my cabinet (get it away from sump to avoid potential mishaps or salt creep) and limited by the 3 ft sensor.
I have a waterproof DS18B20 from a temp controller but i get a error message when I try to connect to head unit. I really don't want to order another sensor as the shipping here to Canada is more than the sensor.
Thanks in advance...

Search for "3 pin fan extension" on Ebay.

Ordered, be here in a few weeks...hopefully.
In the meantime, any issues using the waterproof DS18B20 i have lying around? do i need to update the software? or anything else i should know?
Thanks

You can use it. You'll need to be careful hooking it up, though. Here's the picture I use. The black bars are the ridges on the connector that go facing the back of the unit. DO NOT GO BY WIRE COLOR! Look up the specifications for your probe and match them to the correct pins!

Re: Temp sensor a little short
when i try that my controller reboots. my red wire is vcc, black is gnd and yellow is data???
Re: Temp sensor a little short
If your controller is rebooting then something is wired incorrectly.
Re: Temp sensor a little short
i saw something that said i may need a 4.7 ohm resistor?
Re: Temp sensor a little short
can someone help here please?
Thanks
Thanks
Re: Temp sensor a little short
I don't think you need a resistor. IIRC, that's for older RA head units, unless you were looking at something else. Check polarity one more time. If you're using a 3 pin fan connector then the wire colors will not be correct. You have to go by signal type. Once you get the polarity correct it shouldn't reset, but you will need to cycle the power to get it to see the new probe.
Also be aware that T1, T2, T3 are determined by a serial number internal to the temperature sensor. If your new probe has a lower number, it will be T1.
