This option provides control for systems with isolation valves preventing flow over the cooling towers when not in use.
The CPO 10 application supports optional status inputs which provide feedback indicating whether the chillers, isolation valves, pumps, and cooling towers are on or off. In some cases, the status is only monitored. In other cases, the status can be compared to the command and the device may become locked out if the command and status mismatch for a user-defined period of time.
