Setting Pump Period; Step By Step Proportional Settings - Blue I HydroGuard HG-302 Manual De Uso

When setting the proportional factor in HydroGuard, start with the recommended settings according to the
size of the pool. HydroGuard then learns how to correlate the fluctuations automatically. The fluctuations
eventually get smaller and chemical levels remain close to the set point. Contact Blue I Customer Support
and Training for more information on setting the proper proportional factor for your pool environment

Setting Pump Period

Pump period is a single cycle during which the dosing pump operates and then rests. Proportional control
divides the pump period into two distinct phases: active and at rest.
In general it is recommended to operate in a short cycle, i.e., 00:30 Sec. For large pools, or if you activate
solenoid valves, you may consider longer pump periods.

Step By Step Proportional Settings

1. Finish the installation of all controllers (electrical, water, feeding systems, and electrodes).
2. Calibrate the controller to the water chemical values at the sample point.
3. Set the proportional factor and the pump period of the chlorine and the pH per the recommended setting
in sections 7.5 and 7.6.
4. Let the controller operate the chlorinator and the pH correction devices and make sure that chemicals
are injected into the water.
5. Watch the chlorine and pH as they change. We recommend that you record the values frequently so that
the process is closely monitored.
6. If the values exceed the set point, you need to decrease the proportional factor.
7. If it takes too long to get to the set point, you need to increase the proportional factor.
