Recirculation Modes : External Mode / On-Demand Mode / Crossover Mode
To select a recirculation mode, you must set from the ‘Installer Mode’ on the front control panel.(Refer to the page 34 )
When you use a recirculation mode, there will be some minor efficiency loss, as a result of the water heater maintaining a steady
temperature within the recirculation loop.
With the recirculation operation, hot water will be automatically circulated in the hot water pipes. Even with this function activated,
it may take several minutes for hot water to be completely circulated through the plumbing system. Set the timer to activate the
recirculation system prior to the first use of hot water to ensure hot water is available.
This water heater has a built-in pump and temperature sensor. DO NOT use any external pump or control.(ex. aquastat)
