Main Functions

1. Water Temperature Display: The controller accurately displays the actual water temperature of your solar water heater, ensuring you have real-time information at all times.

2. Water Level Indicator: Easily monitor the water level inside your tank with a clear display that informs you of the current status.

3. Preset Water Levels: Customise your water usage by setting the tank to refill to 50%, 80%, or 100% capacity, ensuring you have the right amount of hot water when you need it.

4. Adjustable Temperature Settings: Set your desired heating temperature anywhere from 0°C to 80°C. For energy savings, you can opt to not engage the electrical booster by setting the temperature to 0°C.

5. Automatic Water Refill: Should your tank's water level decrease, the controller automatically adds water up to your preselected level after 30 minutes, ensuring a constant supply.

6. Smart Temperature-Controlled Water Filling: The controller fills the tank with water if the temperature is above the adjustable preset range (35°C to 95°C, with a default of 60°C). If the water cools down by 5°C below the set temperature, the controller pauses filling. To prevent temperature fluctuations during use, water filling is delayed by 60 minutes and is only operational from 8:00 to 17:00.

7. Manual Water Loading: You have the option to manually initiate water loading and activate the electrical booster as needed.

8. Low-Pressure Protection: If water pressure is insufficient or stops increasing during a 60-minute period, the controller will switch to a low-pressure protection mode, indicated by a displayed symbol. The system will automatically exit this mode after 30 minutes.

9. Programmable Pipe Circulation: Set the timing for the pipe circulation pump to provide hot water instantly and increase water pressure when you open the tap, for immediate comfort and convenience.

10. Winter Pipe Insulation: The "insulation" button activates a self-heating cable to protect outdoor pipes from freezing in lower winter temperatures, operating in 40-minute cycles (10 minutes on, 30 minutes off) to prevent pipe damage.

11. Enhanced Water Pressure During Filling: If your water supply pressure is low, activate the pump to increase the pressure during filling. The pump and electrical valve are synchronized to stop simultaneously once the tank is full.

12. Collector Pipe High Temperature Safety: To prevent damage, if the tank is empty and temperatures exceed 100°C, the controller automatically locks the water loading function, indicated by error code "E4". Water loading can resume once temperatures drop back to 80°C or below, safeguarding against thermal stress and potential glass pipe breakage.
