9.2 Fault Messages

Fault messages on the display fall into three broad categories:

„

Heat pump fault

„

System fault and

„

Sensor fault

You only need to inform your after-sales service if there is a heat
pump fault (HP fault). Make a note of the error message and the
software version displayed in the operating data. After rectifying
the problem, press the Esc button to acknowledge the fault.
The following messages may appear on the display.

NOTE

System fault
In mono energy systems, the minimum return set temperature is set if a
heat pump or system fault occurs. Antifreeze (frost protection) is
ensured. By manually switching to the 2nd heat generator operating
mode, the building is heated exclusively using the immersion heater.

 

A heat pump fault indicates a defect in the heat pump. 

Inform your local technician.

 Details of

the fault (display), the heat pump designation (type plate) and the software version of the heat
pump manager (operating data) are required for rapid and precise troubleshooting. Depending on
the system type, the following heat pump faults may appear on the display:

„

Low-pressure

„

Hot gas thermostat

„

Antifreeze

„

Compressor load

 

A plant fault indicates a defect or a false setting in the heat pump system. 

Inform your local

technician.

 Details of the fault, the heat pump designation and the software version of the

controller are required for rapid and precise troubleshooting. Depending on the system type, the
following plant faults may appear on the display:

„

Motor protection primary

„

Flow rate well

„

High pressure

„

Temp. difference

 

 

As with a system fault, this can be caused by a breakage or a sensor which is short circuiting.

Inform your local technician.

 Details of the fault, the heat pump designation and the software

version of the controller are required for rapid and precise troubleshooting. Depending on the
system type, the following sensors may be defective:

„

Return flow sensor

„

Freeze protection sensor

„

Hot water sensor

„

Flow sensor

„

Sensor for heating circuit 2/3

„

External sensor

 

 

This message will only be displayed with silent cooling active. It can have the following causes:

„

Break or sensor which is short-circuiting

„

Number of room climate control systems does not match the number of set room climate
control stations.

Inform your local technician.
