Main Valve > Auto closing of section valves
Allows to enable/disable the section automatic closing when the main control valve is closed.
On a Seletron system, automatic closing of sections is enabled by default (

•
"M" operation mode
(option
):
section valves are opened or closed by acting on the main control valve depending on the way the controls of the single section valves are set, i.e.:
-if the controls of the sections are set to OFF, and the main control is operated, the sections will remain closed;
-if the control of one or more section valves is ON, by closing or opening the main valve, also the section valves will be closed or opened.
ENABLED MODE CANNOT BE MODIFIED:
this condition occurs when no main valve is installed on the system or the installed one is a
2 ways
valve.
•
"P" operation mode
(option
):
the section valves are controlled independently.
Control functions on the main valve do not affect section valve opening or closing.
