Maintenance
Electronic controller
The battery life of the controller is more than five years under normal working conditions.
These conditions are based on a maximum of two thousand solenoid operations daily. Once
the battery fails, the controller must be returned to "HWM-Water Ltd" where batteries are
replaced.
The internal battery is measured by the firmware all its life. Before the battery fails, the
solenoids are switched to high-pressure and change to low pressure is prevented until the
batteries have been replaced.
The logger will continue to record data in its memory until the battery completely fails. The
data logger cannot be downloaded after this condition occurs.
If any other problem occurs, the logger should be returned to "HWM-Water Ltd", for repair.
The controller is designed for continuous operation over the life of the batteries. You do not
need any maintenance.
Unauthorised servicing will void the warranty and any potential liability for “HWM-Water Ltd”.
