21.3 CONTROL UNIT AND ROOM CONTROLLER ALARM

LAMP

The status lamp on the control unit is used to show ON/OFF status for the

heat pump but also to show possible alarms. The status lamp is therefore

also called alarm lamp.

The room controller alarm lamp can be blocked.

The room controller display is used to indicate alarms for some alarm

categories ( 21.8). The display window slowly flashes red until the

alarm has been acknowledged in the heat pump control unit, or been

automatically reset.

The room controller alarm display function is referred to as an alarm

lamp in this chapter.

The room controller alarm lamp can be blocked.

21.4 ALARM DISPLAY

When an alarm/warning occurs, the display shows information about

what has happened. At the same time, information is saved in the alarm

log and alarm history.

21.5 ALARM BUZZER AT ALARM

At an alarm the alarm buzzer on the heat pump sounds for one second

per alarm buzzer interval set. At certain times of the day the alarm buzzer

can be blocked or blocked altogether.

In the event of a warning, the alarm buzzer does not sound.

21.6 ACKNOWLEDGEMENT OF ALARMS

Acknowledgement means that you have to press to make the

alarm window disappear. What happens after acknowledgement is

described in the respective alarm description.

In most cases, warnings do not have to be acknowledged. The alarm

window disappears by itself once the warning cause has disappeared. It

is, however, possible to acknowledge the warning.

21.7 ALARM TIMER, ALARM MODE

In the event of an alarm that stops the compressor the control unit starts

a timer at 1h. If the fault does not recur additional heat may start when

the timer has counted down.
