Note
To turn off your hot water system.
Additional safety features.
During normal operation the system is left on.
To turn the system off simply press the On/Off
button on any temperature controller (where
fitted). This will shut the water heater down
completely including the temperature controller
digital display.
The on indicator will go out.
If hot water taps are opened when the Rinnai
Infinity is off, cold water will flow from the taps.
If the system is to be left off over the winter be
sure to drain it down if there is a possibility of
free
zing temperatures.
Whilst the hot water tap is open, the following
safety features apply:
• Temperature selection cannot be transferred.
• If a temperature of 43
0
C or higher selected,
and the temperature is decreased to below
43
0
C, and then raised again the maximum
available temperature will be 43
0
C.
• Other controllers are unable to change the
delivery temperature of the water.
The temperature of the outgoing water is constantly monitored by a built in
sensor. If the temperature of the outgoing hot water rises to more than 3ºC
above the selected temperature shown on the digital display, or the preset
limit if controllers are not fitted, the burner will automatically go out. The red
operation indicator will also go out. The burner will ignite again once the
outgoing hot water temperature falls to that shown on the digital display (or
the pre-set limit of the Rinnai Infinity heater).
