HUGO-X1R new feature (attention Rinnai users):


  • HUGO-X1R has added a delay shut-off function.  With the flow sensor connected and activated, when user turns off faucet or shower head, HUGO will remain providing power to tankless water heater for an additional 5 minutes before shutting down.  This allows tankless to be in continuous cycle when user is turning on and off the water during showering or washing dishes.  This "delay" feature also solves the published technical issue with Rinnai users.  This "delay" feature will allow Rinnai's servo valve to perform properly during restart cycle and therefore eliminating the issue of no-flow as identified by some users.
One year manufacturer's warranty on material and workmanship excluding battery. Three (3) months full warranty on included battery.
