Perfect comfort, absolute control. 

For outstanding individual comfort, control and energy management, ZonePlus allows you to have up to four individually controlled zones, each with their own time and temperature settings. For total flexibility, you can upgrade as many Rinnai temperature sensors to Rinnai NC6 or Touch controllers allowing you to fully control, program and manage each zone - eliminating the need for you to go back to a master controller. Adjust temperatures for each zone as it suits you from any controller in the home. 

ZonePlus works in unison with any Rinnai SP series Ducted Gas Heater with 5 or 6 star efficiencies.
