Operation with DTV, DTV II, or DTV+
DTV: The valve is controlled from one or two user interfaces that connect directly to the valve.
DTV II: To connect the valve to the DTV II system, the K-638 media module is required.
DTV+: To connect one or two valves to the DTV+ system, the K-99695 system controller and
K-97172 data cable(s) are required.
Refer to the appropriate sections in this guide for your system configuration.
