P4 comes with two 2-pin JST connectors. The first one is marked APP on top and CONT1 on the bottom. And the second one is marked CONT2. There are two considerations to keep in mind when using these connectors:

1. CONT1 must be open when your device is being configured, otherwise the Blue and White setup window will not pop up when you connect to SAS-XXXXXX network.

2. CONT2 must be open when power is restored or your device is powered up when plugged in.

We recommend that you use CONT1 if you intend to add only one sensor.  In that case, proceed with your device setup as described in the Setup brochure. After it's been setup and tested, add your sensor to CONT1 and configure its message on device configuration page on myspool.com.

Should you choose to use CONT2, make sure that your sensor is normally open. Otherwise, in case of power loss, your device will not restart correctly.

All of these sensors are configured to operate in the normally open mode: a float sensor, a push switch or a door open sensor.  Be aware that our float sensor can be setup to trigger (short) on either high water or low water conditions. It is shipped to send a short on high water. Flip the float 180 degrees to send a short on low water if desired.
