RRS Economizer Controller Quick Start Guide

likely that the flash drive is partitioned or otherwise not com-
patible with controller flash drive functions.

FIGURE 12 - 

Firmware Update

When both a compatible flash drive is connected to the USB
port  and  there  is  navigation  within/re-entering  the  “Update”
section  of  the  parameter  menu,  “USB:  Wait”  will  briefly  be
shown on the top line of the display.

Then,  the  top  line  of  the  display  will  show  “USB:OK”;  the
number  following  “Scan”  on  the  bottom  line  of  the  display
indicates the number of files and folders in the top level of the
flash drive storage.

Once the scan is complete, leave the flash drive connected to
the USB port so it will be available for other functions. A press
of the 

 (scroll up) or 

(scroll down) button will then resume

navigation in the Update section of the menu.

BACKUP FUNCTION

Without  a  flash  drive  connected  to  the  USB  port,  the  steps
listed below for the Backup function only update the “Backup-
Config” restoration file held in controller on-board memory.

FIGURE 13 - 

File Backup Function

With a compatible flash drive connected to the USB port, the

(enter)  button  is  pressed  when  at  (Level  1)  “Update”  >

(Level 2) “Backup” location of the display menu.

“Backing” on the upper line and “UP” on the lower line of the
display  may  be  briefly  observed  immediately  after  the

(enter) button is pressed.

While  the  Backup  is  in  progress,  “Backup:Wait”  alternating
with a countdown timer will be shown on the upper line and
an  increasing  percentage  following  “Backup”  will  be  shown
on the lower line of the display.

In approximately 10 seconds, “Backup:OK” on the upper line
and “Backup 100%” will be shown on the lower line of the dis-
play when  the  Backup function  is  complete.  The flash  drive
may be then be removed from the USB port if not needed for
other functions. A press of the esc (cancel), 

 (scroll up) or

(scroll down) button will then resume menu navigation.

FIGURE 14 - 

Indication Of Incompatible Flash Drive

If  an  incompatible  or  partitioned  flash  drive  is  used,
“Backup:FAIL” will be shown on the upper line and an error
code following “Backup” will be shown on the lower line of the
display instead of the Backup function completion indicators.
