6.0 PROGRAMMING
6.1 INTRODUCTION
It is recommended that the commissioning of the plant is undertaken by a
trained service engineer, who will be able to put the plant into service
quickly, and most efficiently. However, if the services of an experienced
engineer are not available, following the steps outlined below will result in
the system being properly commissioned.
6.2 CONTROLLER SETTING
- Site programming mode
All controller settings will require the valve to have the mains supply
switched on. The valve must not be regenerating when controller
settings are adjusted.
