Replacing the internal battery in the Corrigo controller
There is a battery inside the Corrigo to ensure that the memory and real-time clock
continue to work even in the event of a power failure. When the "Internal battery"
alarm occurs and the battery LED lights up red, the battery is too weak and must be
replaced. Thanks to a back-up capacitor, the controller will continue to operate for at
least 10 minutes even without supply voltage. Please leave battery replacement to
qualified service personnel, as this requires knowledge of proper electrostatic
discharge protection and of how to disassemble and open the WTU.
