The Revo unit with HB option (if available), is supplied with Heater Break alarm contact
normally opened (NO):
• In normal conditions (without alarm) and with auxiliary power supply, the contact to
the terminals has opened (relay coil energized).

closed (relay coil not energized).
If you wish to change the alarm contact open the cover of the Master module (first on
the left with terminal block) and set the jumper as shown in the next page,
