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.
Setting the TIMER mode
In the TIMER operating mode, you can set the times when the heat pump will start and stop. For each timer combination you can
set up to three time periods in which the heat pump will not heat the water.
a) Setting the timer combinations
• Hold field no. 11 for a while (fields 7 and 11 start to flash).
• By pressing fields + or – choose among three timer modes of operation:
- Timer mode of operation of the heat pump for the entire week (numbers 1-7 flash in field no. 7),
- Timer mode of operation of the heat pump for Monday to Friday and Saturday to Sunday
(numbers 1-5 and then 6 and 7 flash in field no. 7),
- Timer mode of operation of the heat pump for each day at a time (individual numbers 1-7 flash in field no. 7).
• To set the time, press field no. 12.
• On the field no. 5, the text 1OF appears and field no. 12 starts to blink.
• By pressing fields + or – set the time of shutdown.
• Press field no. 12 again.
• On the field no. 5, the text 1ON appears and field no. 12 starts to blink.
• By pressing fields + or – set the time of start-up.
• By pressing field no. 12 again, you can use the above procedure to set the second and third period.
• By pressing field no. 12 again, or when field no. 6 stops flashing the set number of days is stored. Again, press field no. 12.
b) Activation, deactivation of timer
• By pressing field no. 11, you can activate the set timer mode.
• The heat pump heats the water in the ON periods (to the set temperature) and in the OFF periods, it does not heat the water.
• By pressing field no. 11 again, you can deactivate the set time mode of operation.

Fan settings
When the pressure drop is defined you select fan mode. It determines the fan speed.
Choose fan mode with the help of the graph (Figure 12), displaying the aerodynamic characteristics of the fan in relation to the
airflow and pressure drop in the air pipeline.
Noise
With the increase of the levels of the aerodynamic characteristics from the lowest to the highest, the nosie also increases. Between
80% and 100% an increase of the noise level can be detected.
