The manual operation of the alarm relays is managed in the menu “Status Relay” or externally via an assigned digital
input. In the manual ON or OFF status, the alarm LEDs at the Gas Controller are lit continuously.

“Status Relay” and to gas alarm.
Relays manually operated in the menu “Status Relay” are canceled again by selection of the automatic function.
Acknowledging the relays in latching mode is also effected in this menu or by a digital input.
