Hey guys im installing a I-VU equipment touch part# EQT1-4-CAR and an App controller part# OPN-APP. I have four rooftop package units. I got a total of four controllers and Four equipment touch. Do each of these controllers control each individual RTU? The units are currently being operated by thermostats in space. Are these things a piece a cake to wire up. Do i need to daisy chain each app controller? Im waiting for tech support to call me back? Any help o will appreciate it..
