DOSING RELAY

The dosing relay can be set to dose above or below the user-programmable pH set point.

OVERDOSE PROTECTION

The small controller can be programmed to shut off a valve, pump, or connected device when activated continuously beyond a selected time.

Adjust from 5 to 30 minutes.

CONTROL MODE SWITCH

With just one switch, normal “Auto” operation can be converted into “ON/OFF” mode.
