How To Set The Temperature - Rinnai RLX94i Installation And Operation Manual

How to Set the Temperature

This water heater requires a minimum flow rate to operate. This rate can be found on the specification page in
this manual. In some cases when you are not getting hot water or if the water alternates between hot and cold,
it is due to the water flow being below or close to the minimum flow rate. Increasing the flow rate should
resolve these problems in these cases.
If you are experiencing issues with higher temperature settings, then reduce the temperature setting. Selecting a
temperature closer to that which is actually used at the faucet will increase the amount of hot water being
delivered to the faucet, due to less cold water mixing at the fixture.

1. If the water heater is off, press
the Power button to turn on.
2. If the Priority light is off, then
press the "Priority button" on the
temperature controller. The
green Priority light will glow
indicating that this controller is
controlling the temperature and
that the water heater is ready to
supply hot water. (The priority
can only be changed while no hot
water is running.)
3. Press the up or down buttons to
obtain the desired temperature
setting.
All hot water sources are able to
provide water at this temperature
setting until it is changed again at
this or another temperature
controller.

Water temperatures over 125° F (52° C) can cause severe burns or scalding
resulting in death.
Hot water can cause first degree burns with exposure for as little as:
3 seconds at 140° F (60° C)
20 seconds at 130° F (54° C)
8 minutes at 120° F (49° C)

VC Series Manual
While any hot water is being provided,
the temperature setting can only be
adjusted between 98° F and 110° F.
Check local codes for the maximum water
temperature setting allowed when used
in nursing homes, schools, day care
centers, and all other public applications.
If a newly installed unit with a controller
has not been powered for at least 6 hours
then the temperature will return to the
default setting of 104° F (40° C) if power is
interrupted.
There may be a variation between the
temperature displayed on the
temperature controller and the
temperature at the tap due to weather
conditions or the length of pipe to the
water heater.
