Flow Control
A variable speed pump controls the water flow rate through the collectors and storage cylinder to optimise the
performance of the system�
Solar Controller
There are two types of Rinnai solar controller available for residential solar hot water systems:
•
The Standard Controller is used with all gas boosted systems and electric boosted systems with an
independently controlled element� It should not be used with an electric tank with a mid sensor port�
•
The Deluxe controller is used for systems with an electric element tank that has a mid sensor port�
Both controllers operate of the pump to optimize solar energy collection and stop energy collection when the
cylinder is full of hot water� They both also have the option of Pumped Frost Protection�
The Deluxe controller has the additional functionality of controlling the operation of the electric element for tank
sterilisation and for optimal performance�
For full details see the solar controller manual�
