* code 028 indicates that the backup battery is used for some
time already and needs to be recharged. Each time the water
button is pressed to tap water, alarm code 028 is displayed
and the tapping is stopped immediately.
When solar radiation is back again, recharging of the battery
starts and code 040 is displayed. It takes approximately 15
