Changing the sanitizer output voltage from the input voltage to 24vac is as follows:
• Remove the jumpers from JP1.
• Set one of the jumpers on JP1 between 3-5,
• Set the other jumper on JP1 between 4-6.
Note: The pH relay output voltage is always the input voltage.

24 VAC Sanitizer Set Up
To wire your 220vac feeder directly to the AT-8 cut and strip the wires 1/4” back and either tin the ends or attach a wire
ferrule.
• BELOW Terminal Block
o AC IN = plug or power to AT-8
o ORP NO = Sanitizer relay output with normally open relay
(no power until relay turned on)
o ORP NC = sanitizer relay output with normally closed relay
(power is on until relay turned on)- commonly used for Salt Chlorine generators.
o pH = Acid or base relay output with normally open relay
(no power until relay turned on)
• ABOVE terminal Block
o l = line voltage, one leg of 220vac
o N = line neutral, one leg of 220vac
o
↓ = line ground, Green Wire

The connectors inside the AT-8 are close together. Failure
to properly terminate wires could lead to shorts between
wires and is not covered by warranty.

Changing the sanitizer output voltage from the input voltage to a dry contact is as follows:
• Remove the jumpers from JP1.
• Replace one of the jumpers on JP1 between 3-4
• The AT-8 will now have a dry contact sanitizer output voltage.

Power should be off to the AT-8 before
moving JP1 jumpers.
