How to wire extended range temp sensor.

[N49atv]

Quick question as I'm pulling wire. How do I wire the indoor/outdoor temp sensor 31A00-7? Instructions say to the OP2, or would I run it to the omnistat2? I'm using it for outside temp display, and humidity adjustment. I'd like it to display on up to 4 T-stats (basement, theater, main, garage)

Thanks

The 31A00-7 is a temperature sensor for the Omni Pro.
You wire it to the controller.
Two wires for 12VDC, one wire to an Omni zone for temperature.
Set the zone to indoor/outdoor extended range temperature.

The -7 doesn't have humidity sensing capability.
You'll need the -8 for that, and it uses a separate zone for the humidity.

The flush mount or surface mount sensors are for the Omnistats.

The controller assumes the first (by zone number) outdoor temperature sensor is the primary, it uses these readings as "the outdoor temperature".
On the Omnistats, they will display this temperature, scrolling between current time and outdoor temp.

Thanks. I'll pull to omnipro. I'm just using outside temp, inside temp, and RH from OS2, to control my target humidity inside. Didn't need outside himidity

Make sure you use the ER setting in PCAccess or else you will get erroneous readings.
