To set the Demand Duo as a circulating system ensure you have selected the DDPCDEL mode by
following the instructions on p.6 (hold button 2 then press 5 >4>5>5 in quick succession).
Demand Duo with a ring main
The system in this configuration* should
have the Demand Duo controller set to the
interrupt settings shown on the next page,
and the ring main pump controller, often
purchased as an additional accessory,
should be left in continuous mode.
If the Demand Duo controller has not been
set, do the below steps.
Bypass advanced setup
The default settings for advanced setup are:
• BMS connection --> open
• Controller ID* --> 1
In the majority of installations just select ‘No’ to bypass.
For more information refer to p.10.
* Controller ID refers to the controller number, you can have up to 16.

To reduce the chance of the system shutting down due to
failed ignition of the Rinnai INFINITY units the tank pump
needs to be set to interrupt. Selection is between 4-10
minutes, for the frequency, and a range of 15-45 seconds,
for the length of time. Rinnai recommend 10 mins/ 30
secs, refer next page for setting instructions.
