Information displayed on the main screen
The display has three main designs. They show different views of the main conditions: Water
Heater ON, Water Heater OFF and Set Up
„Design I“ - Water Heater Off
When the water heater is off, on the screen are displayed date, time, the current temperature of the
water and the condition of the tank's anode protector. If a problem occurs, the indicator for the
condition of the anode protector switches with an error message.
„Design II“ - Water Heater On
When it is on, the water heater works on one of its work modes:
●
Automatic mode with electrical water heating
●
Mode with electrical water heating in a restricted part of the day
●
Combined mode (1,2,3)
●
Solar mode
●
Boiler mode
●
Holiday mode for automatic protecting the solar collector from overheating
Automatic mode with electrical water heating
On this mode the water is heated up only by the electrical heater of the water heater and it keeps the
set temperature. The turned on heater is visualized on the screen by moving “bubbles” above the
heater.
This mode is appropriate when the water heater is intensively used, when hot water is constantly
necessary, when fast heating up the water is required or there is not enough solar energy.
