Temperature Sensors - Hayward OmniLogic Installation Manual

Minimum Clearance between heatsink and mounting surface - 1/8"

Temperature Sensors

Three sensors are included with the OmniLogic. A water sensor and an air sensor must be installed at all times for proper operation. A solar sensor is required
if the solar function is enabled.
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—refer to the plumbing overview diagram.
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.
