whilst the heater is turned OFF, then all functions will be locked. If the heater is turned
OFF whilst the Child lock is activated, it cannot be turned ON again until the lock is
deactivated.
n AUTO COMFORT
A room temperature sensor located at the rear of the appliance is continuously monitoring the
temperature of the room. The main purpose of Auto Comfort is to improve control over the flow of
warm air being discharged through the louvres when the heater is first operated. The means by
which this control is achieved is an 7 speed modulating convection fan and the temperature sensor,
in conjunction with a micro-computer.
In order to achieve comfortable heating, it is preferable to avoid cold draughts from the appliance.
In the case of a conventional fan heater, the convection fan operates normally from the time of
ignition and a cool draught may accompany the flow of air from the appliance.
To overcome this situation, fuzzy logic controls the speed of the convection fan after taking into
consideration the room temperature at the time of ignition. For example: the room temperature is
low, then the fan rotates at low speed. As the room temperature rises the speed of the convection
fan gradually increases.
In this way it is possible to ensure a comfortable flow of warmed air, as well as decreasing the
sensation of cold draughts immediately after ignition.
The convection fan speed increases proportionally as the room gradually heats up. This improves
the warm air distribution, assisting in a reduction of warm air stratification throughout the room, and
resulting in more effective heating conditions.
The micro computer continuously monitors the room temperature and adjusts the convection fan
speed according to the conditions at the time.
-ll-

n FAN RLTER
To protect the room air fan from dust particles or
lint, a filter is situated at the rear of the appliance.
When this filter becomes blocked, the filter
indicator will flash to indicate that it should be
cleaned. Clean the filter weekly during the heating
season to avoid unnecessary strain on the
appliance.
Do not remove filter when appliance is
operating. When the filter requires cleaning,
clean filter before using the appliance, or whilst
the appliance is not operating.
If you do not clean the filter at regular intervals
and the filter indicator is allowed to remain
flashing, then the appliance will stop and [14] will
flash on the Digital Display signifying that the
inbuilt safety device has functioned. You must
clean the filter before operating the heater again.
n HUMIDIFIER TRAY
So that you can humidify the air, your Rinnai RHFE-308FTR is fitted with an enamelled tray at
the bottom of the heater. If you choose to make use of the humidifier tray, it will need filling
about once a day during the heating season. Do not fill the humidifier tray while the heater
i
Tofill the humidifier tray:
Remove the bottom trim panel, below the louvres,
by pulling on both sides. Simply pull the tray
forward to allow it to be filled with water. The
warm air will be humidified as it passes over the
water in the tray. Refit the bottom trim panel after
filling the tray. The RHFE-308FTR is a very high
efficiency appliance, during operation a small
amount of condensation is produced in the flue
system, this drains into the enamelled humidifier
tray.
The humidifier has the benefit (when filled with water) of raising the humidity in the air. With increased
humidity, the heater can actually be run at a lower temperature while still maintaining the same level
of comfort.
n VERTICAL LOUVRE ADJUSTMENT
The warm air flow direction may be altered by
inserting a screwdriver or similar tool and gently
bending the vertical louvre(s) either to the left or the
right.
Note: These louvres are not designed to be
adjusted more than 6 times.
