VIII.2 Changing the battery
This operation requires good knowledge of DES (electrostatic discharges and wearing a bracelet or any other earthing
accessory)
When the “low battery” alarm appears and the red indicator lights up, this means that the emergency battery for memory
and real-time clock back-up is too weak. The procedure for changing the battery is described below. The controller of the
VORT NRG EC unit is fitted with a condenser to back-up the memory and to operate the clock for about 10 minutes after
the current has been cut. If the battery change operation takes less than 10 minutes, there is no need to reload the
schedule and the clock continues to function normally.
The spare battery is of CR2032 type.
Press on the clips on each side of the box with a small screwdriver to detach the base cover. Hold the base and remove
the coverTake the battery and slowly pull upwards until the battery has left its housing.
Take a new battery and slide it into the housing. Take care to insert the battery in the correct
direction to match with the polarity.
