Configure Friedrich VRP VTAC

Friedrich VRP VTAC Configuration Guide

***There are two different versions of the VRP model that require different types of wiring connections. Be sure to follow the below connection steps and wiring guide for the appropriate unit type. In order to connect the Anacove HVAC Controller Gateway to this unit you must use an Anacove Smart Serial Adapter. If you do not have the Anacove Smart Serial Adapter then reach out to your Anacove Account Representative. The HVAC Controller Gateway should always be mounted as close to the return of the VTAC as possible.***
