• If you do not press any field for 10 s, the programme returns to the start menu.
• If the code is incorrect, the programme returns to previous operation.
• If the code is correct, the first parameter appears on the display. The number on the right is the serial number of the parameter
and the field on the left is intended for its value.
• The first parameter

• :
27
low temperature mode YES/NO
• :
34
PV function YES/NO
•
:39
interval setting for anti-legionella function activation
• :

•
:45
temperature settings °C or °F
Fan speed settings (parameter: 21)
Select the parameter
:21
and set the fan speed by pressing (

Setting low-temperature mode (parameter :27)
Select the parameter
:27
and change the temperature by pressing (
+
) or (
-
). The temperatures depend on the model of the heat
pump.
The low-temperature mode is possible only if the heat pump model enables this function!****
The settings are shown on the left side (in the field TEMP):
Yes
– heat pump model ZGNT, operation mode of the heat pump (higher than -7°C), the system contains a 4-way valve.
No
– heat pump model Z, ZG, operation mode of the heat pump (higher than 7°C), the system does not contain a 4-way valve.
PV function activation (photovoltaics) (parameter :34)
Yes
– activated
No
– deactivated
Anti-legionella function (parameter :39)
• Select the parameter (
:39
) and set the interval for the anti-legionella function activation (0 to 60 days) by pressing (+) or (-).
See the numerical value settings on the left side in field
5
. When the interval of the anti-legionella function activation is set, the
changes are saved automatically after a few moments, or manually by pressing field no.
4
. If the parameter (
:39
) is set to 0, the
anti-legionella function is inactive.
• Factory settings of the anti-legionella function activation: Every 14 days of the heat pump operation, if the water temperature in
the previous 2-week period did not exceed 65 °C continuously for at least an hour.
• The anti-legionella function works only when the heat pump is switched on. When activated, symbol no.
17
is displayed.
• The anti-legionella function can be activated manually by pressing field no.
15
.
• The anti-legionella function can be disabled by switching off the heat pump when pressing field no.
9
.
Warning: If heating when the anti-legionella function is activated, the boiler water temperature is 65 °C regardless of the
temperature set on the appliance.
