Using Hot Water
To operate the heater, simply turn any hot water
tap on. This will automatically light the burner
providing hot water. The red IN USE indicator
will glow on the temperature controller.
To turn off your hot water system
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 Digital Monitor will go out.
If hot water taps are opened when the Rinnai 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
freezing temperatures.
Using High Temperature Display Controllers
You will need to program the Master controller if you want to display and use
temperatures over 50°C. Programming only needs to be done on Master
universal controller; other universal controllers will not allow this.
Deluxe Kitchen controllers are supplied already programmed to allow high
temperatures.
STEP 1: On the Master controller only press and hold the Transfer and ON/
OFF buttons simultaneously (see Fig. 1) until a “beep” is heard (approx. 5
seconds).
STEP 2: When the Primary controller is switched on it should be possible to select temperatures higher
than 50ºC. If not repeat STEP 1.
If the master controller is replaced, repeat STEP 1 above
for the new controller.
