VSX OPERATING MANUAL
automatic operation. Also note that the maxi-
mum number of Skip Days is 999 days, or
approximately 3 years.
Pump: Every VSX controller has a separate
Pump output (red and white striped wire from
the power supply board in conventional sys-
tems, station number “0” in decoder systems).
The Pump option designates whether the
specified Program will automatically activate
this output.
The Pump output may activate a pump start
relay (such as Hunter Industries PSR series
relays) connected to a pump, or it may be used
to control a master valve. The Pump output
must never be connected directly into a high-
voltage switch (see installation instructions for
further information).
In systems where the pump is activated by the
individual controllers, this option is used to
provide pump pressure to the Programs that
require it, and to operate without it for any
Programs that may not require it. For example,
if your controller operates both rotors and spray
heads connected to city water, you may have a
booster pump to provide additional pressure for
the rotors. In this case you could have the Pump
option set to
“Yes”
for the Programs containing
the rotors, but
“No”
for the Programs containing
the spray heads (if they would be over-pressur-
ized with the booster pump).
Keep in mind that if any controller in the
system activates the pump, it is activated
regardless of whether any other controllers are
running Programs with Pump
“No”
selected.
To set the Pump: Press PROGRAM SELECT
until the name of the Program you want to set
the Pump for appears. Press OPTIONS until

appears. Press ENTER. The

The current selection will be capitalized
(default is

“no”
selection will be in
lower case. Press the TOGGLE button to
switch between

NO
. When it is
correct, press ENTER. The display will flash
“SAVED!”
and your selection. After a moment,
the display will revert to
Use Pump?
You may
now press the OPTIONS, BACK, or NEXT
buttons to view more options, or you may press
EXIT to leave the Program Options mode.
