By pressing the button, the temperature gets 1°C higher, by pressing the button it gets
1 °C lower.The setting range is 5°C ~ 40°C.
Then choose one of the following heat pump operational modes:
1. HEATING function (display shows a sun symbol). Heat pump turns itself off after a
requested water temperature is reached. Heat pump turns itself on again when the water
temperature decreases by 2 degrees of Celsius below the requested water temperature. The
temperature difference of 2 degrees of Celsius is called Hysteresis. It is possible to change this
settings (please see section
5.2 Setting of the operating parameters).
2. COOLING function (display shows a snowflake symbol). Heat pumps turns itself off after
requested water temperature is reached. Heat pump turns itself on again when the water
temperature increases by 2 degrees of Celsius above the requested water temperature. The
temperature difference of 2 degrees of Celsius is called Hysteresis. It is possible to change this
settings (please see section
5.2 Setting of the operating parameters).
3. AUTO-MODE function (display shows a triangle symbol). Heat pump automatically keeps
the requested water temperature, i.e. heat pump automatically heats and cools when the
difference between water temperature and the requested water temperature is 2 degrees of
Celsius. The temperature difference of 2 degrees of Celsius is called Hysteresis. It is possible to
change this settings (please see section
5.2 Setting of the operating parameters).
Recommendation: Manufacturer recommends
heat pump regulation by AUTO-MODE.
Warning: Manufacturer does not recommend changing of
hysteresis settings. It may be changed by an experienced user only.
5.4 Checking of the current value of some parameters
Keep the button pressed for 3 seconds during the device operation to check the current
status. By pressing the button, you can control the output water temperature and the
temperature on the compressor discharge.
14 – input water temperature 17 – outdoor heat exchanger temperature
15 – air temperature 18 – output water temperature
16 – temperature on the compressor discharge
Note: 10 seconds after the last pressing of the button, the display switches over to the standard
adjusted water temperature/current water temperature display.
