Using the above settings, when there is system demand, the AQUAVAR pump will start first and
maintain pressure until it reaches 58 Hz. At that point, the relay will start the slave pump at full
speed. As soon as the slave pump is started the AQUAVAR pump will reduce its speed and continue
to vary to maintain constant pressure. If demand is reduced and the AQUAVAR controlled pump
slows to 40 Hz, the slave pump will be turned off. At this point, the AQUAVAR controlled pump
would increase speed to continue to maintain constant pressure.

system or “hunting” or oscillation of pressure will occur.
