6.1 Rechargeable battery
• The monitoring of the temperature alarm system and the temperature display during phases without
power supply are maintained by an integrated rechargeable battery.
• The battery is charged during phases with solar power.
• If the capacity of the battery is no longer sufficient to take over the control function, the alarm message
“E4.2” appears on the display.
• If no battery is connected, the system will generate an „E4.1“ alarm message.
• The battery should be pre-emptively replaced every 5 years or when alarm E4.2 appears. This
replacement must only be carried out by a recognised service technician.
• The battery is a lead-acid storage battery that must be disposed of separately in the case of a fault.
