Fluctuating water pressure and/or
flow is causing the flow switch to cycle
on and off.
Increase the flow rate.
Be sure that the isolation valves are properly adjusted.
Be sure that the inlet filter screen is clean.
Be sure that the outlet restrictors and aeratots on showers and/or
faucets are clear.
Be sure that there is no plumbing crossover by shutting off the inlet
isolation valve and opening an hot water outlets served by the Tronic
3000C Pro. If there is a steady flow, then cold water is flowing into
hot water service lines and back-pressuring the Tronic 3000C Pro.
This condition must be fixed or the heater wil not work properly.
