VRP Remote Upgrade Procedure

Introduction
The Remote Upgrade procedure on the Friedrich VRP system is designed to greatly reduce the
amount of effort required in upgrading the system firmware. The procedure can upgrade the
Friedrich Main Controller (FMC), Wall Controller (WC), and Motor Control System (MCS) boards. It is
capable of upgrading just one board, all the boards at once, or any combination of any two boards.
All that is required from the user is having a correctly formatted SD Card that is inserted into the
Wall Controller. After insertion into the SD Card slot of the Wall Controller, the process is
autonomous and regular operation resumes after a successful update.
Setup
In-Board SD Cards
The first step in making sure the unit is properly configured for Remote Upgrade is ensuring that
there are SD Cards in both the FMC and MCS boards. If the procedure is started without these cards
present the WC will display an error and the procedure will terminate [See Errors].
Procedure
To Remote Upgrade, the Wall Controller (WC) must be Version 03.02.00.00 or higher, Friedrich
Main Controller (FMC) Version 03.02.00.07 only, and Motor Control System (MCS) Version
03.02.00.04 only. The Wall Controller can be upgraded from any version to 03.02.00.01 by inserting
the "WC 3.2.0.1" SD Card. If the FMC or MCS version do not match the above, a direct upgrade must
be done.
