Temperature Sensors
Water Sensor
This sensor is used to measure the pool/spa temperature and is installed in the filtration plumbing
after the filter but before either the solar or conventionally fueled heaters.
1. Drill a 3/8” (10mm) diameter hole in the PVC piping and remove all chips and burrs.
2. Insert sensor until O-ring collar sits flush on the hole.
3. Position hose clamp over the sensor and gently tighten until O-ring makes an adequate seal.
Do not overtighten.
Air Sensor
Mount the air sensor outdoors. IMPORTANT: The air sensor must not be mounted in direct sunlight.
Solar Sensor
For solar applications, mount the sensor near the solar collector array so that it is exposed to the
same sunlight as the collectors. Use additional cable (20 AWG) if necessary.
Optional Valve Actuators
Currently, using an Hayward GVA-24 actuator or equivalent requires that the Hub be powered with
230 VAC. If powering the VS Omni Hub with 115 VAC, an actuator can't be used. For installation,
refer to the mounting instructions included with the unit. After configuring and first operating the
valve, note that the internal cams in the actuator may have to be adjusted depending on the way the
actuator is mounted on the valve and the desired valve action.
Plumbing
Optional Flow Switch
Only applicable if leak/clog detection is desired. The flow switch should be plumbed on the return
side at the very end of the pool pad plumbing. This will ensure that if a leak occurs anywhere at the
pool pad, the VS Omni will be able to detect it. Understand that if a leak occurs after the flow switch
(downstream), the VS Omni will not sense a no flow condition.
IMPORTANT: There must be at least a 12” (30cm) straight pipe run before (upstream) the flow switch.
IMPORTANT: To ensure proper operation, verify that the arrow on the flow switch points in the direc-
tion of water flow.
Variable Speed Pump
Refer to the included VS Omni Pump manual for plumbing information.
