Mode with electrical water heating in a restricted part of the day
On this mode the water is heated only by the electrical heater of the water heater, as its work can be
restricted by setting intervals of the day when the heater is on. The beginning or the end of the work
period are displayed on the left side of the screen. The start time is displayed when it hasn't come
yet, and after the heater turns on the end time is displayed. The turned on heater is visualized on the
screen by moving “bubbles” above the heater.
This mode is appropriate in cases when the solar energy is not enough for heating up the water or
allows usage of the cheaper night electricity.
Combined mode 1: A solar collector and an electrical heater restricted by a timer
On this mode the water is heated up both by the electrical heater of the water heater and by the
serpentine which is connected to the solar collector installation, as the heater can work only on
certain periods of the day. The beginning or the end of the work period of the heater is displayed on
the right side of the screen. The start time is displayed when it hasn't come yet, and after the heater
turns on the end time is displayed. The turned on heater is visualized on the screen by moving
“bubbles” above the heater. When the circulation pump of the solar installation turns on, this also
appears on the screen.
The combined mode allows full use of the solar energy for heating up the water during the day and
use of the electrical heater for keeping the temperature during the night or for additional heating up
the water when the solar energy is not enough.
