  • Page 8: Zs Sensor Screens

    Which screens should display what information The ZS Pro and ZS Pro-F sensors have the following screens that you can assign information to. Home Screen: This is the initial screen that a user sees. It typically displays the zone temperature. We recommend that you keep the Home Screen simple and uncluttered.

  • Page 9: Creating Snap Control Programs For Zs Sensors

    • Multiple control programs, you can wire up to 15 ZS sensors to its Rnet port. A control program can use no more than 5 ZS Sensors, so you must use multiple control programs if your Rnet network has more than 5 sensors.
