Default ebay temp controller with RIMS

Hi, I noticed that not many people use the ebay temp controller with their RIMS system. Would there be an issue with me using this cheap controller to operate a 110V gas solenoid by placing the stock probe into a heat-shielded thermowell?

Thanks.

The ebay controller should work the same as a LOVE or similar, and those are used for running gas solenoids, so I don't see why not.

As for protecting the sensor - I'm not sure. You could probably encase it in a thermowell...or try just dropping it into the hot water, (it IS meant for an aquarium, after all...).

As with all gas control. just because it CAN run by itself, doesn't mean it's safe to walk away from it for any length of time.

The problem with those controllers is that they use a thermistor probe and are really slow to respond to temp changes,
for a RIMS use a RTD probe, K-type at least

can you hook up a different probe to the eBay controller?

No they only can use a thermistor, a real pid is your best bet like a Aurber,Love, Johnson stc.

I use two of them in the control panel of my gas fired HERMS. One controls the HLT burner, and the other controls the pump. I use the slightly cheaper single stage units that read in fahrenheit, and they have nice round SS probes, as opposed to the oval rubber probes on the STC-1000. They fit snugly inside 1/4" od copper, which makes for cheap and easy thermowells. They might not be ideal, but they work well enough for me.

Can you post a link to the 'slightly cheaper single stage units'?
