CONNECT TO ELECTRICAL SUPPLY

Standard Controller
Twin element storage cylinders are wired for non simultaneous operation. The electric supply should be 'Off-Peak'
(overnight) to the bottom heating unit and continuous to the top heating unit�
The power supply to a single lower element model should be Off-Peak (overnight).
The power supply to the element of mid element solar storage cylinder can be Off-Peak (overnight), extended Off-
Peak (overnight and day) or continuous or other tariffs available from the local electricity supply authority.
Rinnai strongly recommends the use of an Off-Peak tariff to ensure that solar heating takes priority over electrical
heating� If this isn't available, then a timer can be used to limit electrical heating to non solar hours�
