Test mode is not automatically ended (no monitoring of time-out!).
Only authorized personnel should override the inputs – and for a limited period of time
only!
During the test mode, fault status message “Boiler test operation active“ appears. This
display is maintained until “Test operation“ is reset to “----“. This ensures that the plant
is not quit before test operation is ended.
In position “----“, the boiler is released and receives its presettings from the boiler
sequence manager.
The boiler is shut down, that is, burner and pumps are switched off.
The boiler is released. The aggregates (shutoff valve, maintained boiler return tempera-
ture with mixing valve, boiler pump) are active, but the burner is still switched off.
The boiler is released and the burner with its stage 1 or basic stage maintains the
adjusted test mode setpoint.
