14 ALARMS
14.1 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 display is used to indicate alarms for some alarm
categories (

Table 46 ). 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 alarm lamp in
this chapter.
The room controller alarm lamp can be blocked.
14.2 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.
14.3 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.
14.4 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.
