HOW TO FORCE TAKING NEW PRESSURE READINGS
FROM THE SYSTEM SCREEN SELECT THE HGM300 THAT NEEDS A NEW PRESSURE READING AND PRESS THE BUTTON TO THE LEFT OF THAT HGM300. THIS WILL TAKE YOU TO THE HGM SETUP SCREEN.
ON THE BOTTOM RIGHT SIDE OF THIS SCREEN PRESS THE BUTTON TO THE RIGHT OF “SERVICE MODE ENTRY” TWO TIMES WITHIN THREE SECONDS. THE HGM300 RED ALARM LIGHT WILL NOW BE FLASHING. PRESS THE BUTTON TO THE RIGHT (THE SCREEN NOW SHOWS “IN SERVICE QUIT” FLASHING) TWO TIMES WITHIN THREE SECONDS.
THE RED LIGHT WILL GO OUT ON THE HGM300. RETURN TO THE SYSTEM SCREEN.
UNDER THE HGM300 SELECTED IT WILL DISPLAY “PRESSURE CHECK”, THEN IT WILL DISPLAY “PURGE” AND FINALLY IT WILL SHOW GOING FROM ZONE TO ZONE.
ONCE IT DISPLAYS A ZONE YOU CAN GO BACK TO THE DIAGNOSTIC SCREEN TO VIEW
THIS MAY NEED TO BE REPEATED SEVERAL TIMES WHILE WORKING WITH FLOW FAULTS.
