Hayward OmniHub sensors don't work

[mecohen]

Hi,

Installed a Hayward OmniHub, added mother-board to AquaRite and all works great.
Get stats and can control my VS900 and SWG remotely.
Connected both air and pool sensors to get temperature, but do not get any output.
Any suggestions are very much appreciated.

Check the wire connections for the temperature sensors.

Post pics of the temperature sensor connector.

You have a multimeter?

Yes, I do have a multimeter.

Hi Allen, I posted pictures. Any idea what's wrong?

I would check that all the wire ends are stripped back and making a good electrical connection in the connectors. You may have tightened the connector onto the insulation of a wire instead of the bare wire. I can't tell from the pics but I don't see any bare wire going into the connector blocks.

If you can get multimeter probes into the connections measure the resistance of each temperature sensor.

I assume you have tested it but just wanted to make sure, OmniLogic won't display pool temp unless the flow switch has tripped (i.e. it detects the pump is operating). Very strange design.... so if your troubleshooting with the pool off, that might be it.

Post your XML file and maybe we can see something in there.
