You've gotten good answers already, but I want to clarify a couple of points. Firstly the SKU 521903 should include the WiFi Link Kit as part of the bundle, so you should make sure you get all of that - it looks like below with 2 antennas and both a power and ethernet cable. Secondly, the consumer edition of the Wi-Fi product that DB-Cooper linked to isn't directly compatible - you need ENS202EXT-PTC not ENS202EXT. You can get the latter working, but not through the IntelliCenter screen as I suspect there is custom firmware involved. Anyway, as already stated all programming can be done through the touchscreen on the panel - you might even be able to call Pentair support to walk you through the Setup Wizard which is a step-by-step system configuration.Does intellicenter requires WiFi to be able to operate? I thought it comes w a remote control like TV. My husband said he didn’t see it in the pkg. he almost gave me an heart attack telling me that intellicenter only works w WiFi according to Youtube. We don’t have WiFi out at the equipment pad. The intellicenter i8 with IC60, master temp just got installed. The plumber and Electrician installed and said they don’t know how to program it. The gas guy hasn’t came yet. My PB is coming in Wed.
