LOCKING CODES
The following graphs describe the blocking codes of the water heater. A blocking code is a temporary blocking of
the water heater, because of an extraordinary situation. The water heater will continue to operate after stabilisation
of this situation.
The display is not blinking, but is lightened up during the blocking period.
The water heater is blocking an action because of an extraordinary situation. This action will be continued after
