Safety devices

3.2.1

Frost protection function

The frost protection function for the system is controlled us-
ing the product itself or using the optional system control. If
the system control fails, the product guarantees limited frost
protection for the heating circuit.

3.2.2

Low-water pressure protection

This function continuously monitors the pressure of the heat-
ing water in order to prevent a possible loss of heating wa-
ter. If the water pressure falls below the minimum pressure,
an analogue pressure sensor switches off the product and
switches the other modules, where these exist, to standby
mode. The pressure sensor switches the product on again if
the water pressure reaches the operating pressure.

If the pressure in the heating circuit is

≤

0.1 MPa (1 bar), a

maintenance message appears below the minimum operat-
ing pressure.

–

Min. heating circuit pressure:

≥

0.05 MPa (

≥

0.50 bar)

–

Min. heating circuit operating pressure:

≥

0.07 MPa

(

≥

0.70 bar)

3.2.3

Freeze protection

This function prevents the outdoor unit's evaporator from
freezing when the heat source temperature drops below a
certain value.

The outlet temperature of the heat source is constantly
measured. If the outlet temperature of the heat source falls
below a certain value, the compressor temporarily switches
off and displays a status message. If this fault occurs three
times in a row, it is switched off and a fault message is
displayed.

3.2.4

Pump blocking protection

This function prevents the pumps for heating water from
sticking. The pumps, which were out of operation for
