Programming - Rinnai service menu
This mode is accessed if setting up the system and controller for applications that may experience
high winds, where the Rinnai INFINITY commercial units could lock out on occasion due to the
wind stopping ignition or an interruption to the gas supply. Setting up the system to automatically
restart/reset could avoid costly service callouts.

Pump operation
This allows the option of alternating or boost. Select and press button 2 ‘OK’. Alternating is
the preferred option, but boost will energise both pumps simultaneously, for ringmains that
are poorly designed and experience considerable heat loss.
Changing mode
Interrupt mode breaks the power supply to the pumps for a short period of time, and
allows for the Rinnai INFINITY commercial units to be stopped. Select interrupt and press
button 2 ‘OK’.
There are a series of options within this feature that allow you to select when the interrupt
mode activates, and the length of time the power remains off. Select ‘INTERRUPT AFTER’
and enter 28 minutes for DDSTAT, and 10 minutes (DDPCDEL), and ‘INTERRUPT FOR’
30 seconds (range 15-45 seconds).
Reset pump and error settings
Once interrupt mode has been programmed there are three more screens; reset pump
run hours, view and clear error logs, and the option to clear all the errors and settings by
resetting the micro.
