* With the recirculation operation timer set, 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 instantly available.
* Multiple recirculation time periods can be set.
* Until the timer is deactivated ( p.29), the recirculation
system will operate daily at the set times.
* When the recirculation system is turned “OFF” by
the timer, the water heater will still remain “ON”
and can be used normally.
