Figure 11: Temperature settings, switch on "TURBO" and "HOT" mode
Setting the temperature
• Press field no. 5 (the set temperature starts blinking).
• By pressing + or – you can change the temperature setting from 10 °C to 75 °C or 10 to 65 ° C (Z models), preset to economic
temperature of 55 °C.
• The setting is stored by pressing field no. 5 again, or when field no. 5 stops flashing. After a few seconds, the display shows the
actual temperature. The set temperature should suffice actual needs. Recommended temperature settings are between 45
and 55 °C. Higher temperatures are not recommended as they reduce the efficiency (COP) and extend the time of heating or
increase the number of operating hours.
• In case of power failure, the last stored value is restored.
Switching on the "TURBO" mode (Models ZG in ZGNT)
• If you need more warm water than the heat pump can heat up in a short period of time, press field no. 13 (switches on the
"TURBO" mode). The heat pump and heater work simultaneously. The screen shows symbols no. 14, 16 and 20. When the
temperature reaches 55 °C the heat pump returns to the mode used before the "TURBO" mode.
• With models without the heater the water is heated only by the heat pump. The function does not offer the option of accelerated
heating.
Switching on the "HOT" mode
• If you want to heat the water to the maximum temperature of 75 °C, press field no. 15. The heat pump will heat water to 55 °C.
The screen displays symbols no. 16 in 20. When the temperature in the boiler reaches 55 °C the electric heater turns on to heat
the temperature up to 75 °C. The screen displays the symbol no. 14. When the temperature reaches 75 °C the heat pump returns
to the mode used before the "HOT" mode.
• With models without the heater the function is inactive
Display of the quantity of water in the heat pump
The display shows the symbol 18:
•
- no warm water
•
- low quantity of warm water
•
- high quantity of warm water
Setting the vacation mode
In the vacation mode, you can set the number of days (maximally 100), when the heat pump shall maintain the minimal
temperature of water (approximately 10 °C).
• Hold field no. 6 for a while (fields 5 and 6 start to flash).
• By pressing fields + or – you can set the number of vacation days shown in field no. 5.
• By pressing field no. 6 again, or when field no. 6 stops flashing, the set number of days is stored.
• If you set the value to 0, then the heat pump will resume its normal operating mode after confirming the setting, and illumination
of field no. 6 will turn off.
• After the set number of days has elapsed, the heat pump returns to the normal mode and illumination of field no. 6 turns off.
The Z version
With models without the heater the minimum temperature is provided only by heating with the heat pump. In case of higher or
lower air temperatures from the temperatures of the heat pump operation the water will not heat.
With models without the heater (Models Z) the water tank with the heat pump is without freezing protection!
