                Setting the Recirculation 

System Operation Timer

For “System [ Rcrc ]”

This example describes setting the recirculation 

system to operate between 5:00 am - 8:00 am. 

•  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 (See page 17), 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.

•
