Section 4. Synchronization
4.1
Synchronization Methods
If the valve is plumbed in the
position and the actuator is mounted in
Mounting
position, you do not have to change the cam
settings from the factory settings. However, you may
have to synchronize the cams.
One of the following will occur when the actuator is out
of synchronization:
•
the actuator will rotate in the wrong direction
in relation to its controller (as in a solar heating
system)
•
one actuator will rotate incorrectly in relation to
another actuator (as in pool/spa combination)
Figure 7 illustrates an example of the valves and
actuators of a pool/spa combination that are out of
synchronization. The valve on the left of the illustration
(suction) is plumbed with the spa line on the left side
of the valve and the pool line on the right; whereas, the
valve on the right of the illustration (return) is plumbed
with the pool on the left side of the valve and the spa
on the right. In this configuration, if the actuators are
activated, one will turn to spa while the other will turn
to pool. The actuators will have to be synchronized.

Figure 7. JVA Synchronization, Example
On the actuator that is out of synchronization, flip the
toggle switch located on the bottom of the actuator to
the ON 2 position (see Figure 8). The toggle positions
are marked on the actuator top cover. Retry the system.

Resetting the Cams
WARNING
Improper cam settings can result in dead heading
of the water flow which can cause injury or property
damage. Improper cam settings and/or operation will
void the warranty.
NOTE
Before resetting cams, if the valve is plumbed in
Standard Plumbing position and the actuator is in
Standard Mounting position there is no need for
resetting the cams (see Figure 9). If a port other than
"B" is plumbed as the common port or if the actuator
is mounted other than Standard Mounting, the cam
setting must be changed so the actuator shaft and
the valve diverter rotate properly. Refer to the Cam
Setting Chart on page 8 for proper settings.
