Starting/stopping the heat pump
• To start the heat pump, hold field no. 9.
When the appliance is switched on, the fan starts first and operates for one minute (symbol no. 20 is displayed). If the
temperature of inlet air is appropriate, the controlling unit switches on the compressor and the heat pump operates in normal
mode (symbols 16 and 20 are displayed). The heat pump is on, the screen remains unlit and inactive.
In 60 seconds after the last touch of the screen, the illumination and activity of the screen are turned off, but that does not affect
the operation of the heat pump. Pressing anywhere on the screen re-activates the screen and its illumination.
If trying to start up at a lower temperature, please see chapter "Operation at lower temperatures".
• By holding field no. 9, the heat pump is switched off.
The appliance stops functioning and the only field visible on the screen is field no. 9. (If you switch off the heat pump for a longer
period of time, the water must be drained from the pump if there is any danger of freezing).
Power failure protection
In case of power failure, the settings remain stored for up to 23 hours.
After restarting, the heat pump operates in the same mode it was operating in before the power failure.
Operation at lower temperatures
a) The ZGNT version
When the appliance is switched on, the fan starts first and operates for one minute (symbol no. 20 is displayed). If the temperature
of inlet air is lower than -7 °C, the fan is turned off. Domestic water is heated with heaters. The heat pump operates in the reserve
mode (symbol no. 14 is displayed). The possibility of switching to normal mode is checked every 2 hours by switching on the fan
for one minute. If the temperature of inlet air is higher than -7 °C, the heat pump switches to normal mode of operation (symbols 16
and 20 are displayed). The heaters switch off. The heat pump is on, the screen remains unlit and inactive.
At lower air temperatures, the evaporator defrosting cycle is started if necessary. Symbol no. 19 is displayed on the screen. The
fields 2, 4, 6, 11, 13 and 15 remain inactive. Defrosting takes place until the conditions for normal operation of the heat pump are
achieved.
After successful defrosting, the heat pump returns to normal operation (symbols 16 and 20 are displayed).
If defrosting is unsuccessful, the controlling unit displays an error message. Field no. 4 starts flashing, accompanied by warning
beeps. By pressing field no. 4 the warning beeps can be turned off. Error code E247 appears in field no. 12 and the pump switches
automatically to heating with electric heaters. The screen displays symbol no. 14. The error code can be deleted at any time by
pressing field no. 4. Field no. 12 resumes to displaying time.
b) The ZG version
When the appliance is switched on, the fan starts first and operates for one minute (symbol no. 20 is displayed). If the temperature
of inlet air is lower than 7 °C, the fan is turned off. Domestic water is heated with heaters. The heat pump operates in the reserve
mode (symbol no. 14 is displayed). The possibility of switching to normal mode is checked regularly. If the temperature of inlet air
is higher than 7 °C the heat pump switches to normal mode of operation (symbols 16 and 20 are displayed). The heaters switch off.
The heat pump is on, the screen remains unlit and inactive.
c) The Z version
When the heat pump is not equipped with a heater, certain functions (backup mode), described under b) cannot be used. In case
of temperature increase or decline these pumps cannot heat water. The possibility of switching to the normal operation mode
operation is cyclically checked.
With models without the heater (Models Z) the water tank with the heat pump is without freezing protection!
