Regular checks

6.1

Checking operation

During normal operation, the alarm indicator lights green continuously to show that everything is OK. When an

alarm is triggered, the display will flash and the indicator will flash green at the same time as a text message is

shown in the display.

ALARM

OUTDOOR SENSOR

Regularly check the alarm indicator to ensure that the installation is

working correctly. In event of alarm the heat pump will if possible sup-

ply heating to the house. Primarily with the compressor, secondarily

with the auxiliary heater. Hot water production will stop to indicate

that something noteworthy has occurred.

In the event of an alarm this is indicated in the display with the text ALARM and an alarm message/alarm code.

Examples of potential alarm messages:

Message

Meaning

OUTDOOR SENSOR

Something have likely happened to the cable connection to the outdoor sensor, the

cable itself or the sensor. Check for physical damages. Contact your installer if the

alarm persists.

SUPPLY LINE SENSOR Contact the installer for further assistance.
Other alarm message Try to reset the alarm as follows. If the alarm remains contact your installer.

Resetting the alarm

For alarms that are not reset automatically, acknowledgement is required. Acknowledge the alarm by setting

the heat pump to operating mode OFF and then back to the desired operating mode.

If the alarm remains contact your installer.

NOTE! Don't leave the heat pump in OFF-mode due to risk of freezing damages in low outdoor temperatures.
