Hydros Slim Temp Probe Reading Low

E.intheC · Apr 7, 2023

I just installed a Hydros Control x2, the Wi-Fi power strip, and the hydros ato system. All worked well and it was way to setup.

The slim temperature probe was also easy to setup, but the temp is wrong. It’s currently reading 71.2 degrees. My heater is set at 78, and I have a digital temp gauge that says the tank is 77. I’ve been reading and it looks like the probe cannot be calibrated.

Has anyone had this issue?

If you select the temperature icon at the graph there is an option to set an offset.

Is the probe in the same place as the one you are using as a standard? Also give it some time to acclimate to the temp of the water. I have three of these and they are all close to each other. Also try unplugging it from the controller wait a minute and plug it back in to reset the chip inside the sensor before using the offset to get it to match the one you want it to match.

Thank you for this - the offset only allows you to change it by 3 degrees.

Thank you - I’m going to try unplugging and plugging back in.

If that does not work then submit a support ticket here https://support.coralvue.com/submit_ticket#login . Is there anything else plugged into the other sense port? If so unplug it and see if that corrects the issue. The ports share a 5 volt supply in the controller.
