1. Introduction
Background
The RHFE-308FTR incorporates an improved modulating control system to provide comfortable heating.
Other features of these appliances are improved safety, operation, installation, and maintenance features.
Characteristics
• Built into the main PCB is the software for connection to a central ON-OFF control.
• Gas flow modulates in 7 steps between High and Low ensuring comfortable and efficient heating.
• Includes a 24 hour digital clock and dual timer, and an economy mode function. This reduces gas consumption without affecting comfort.
• Temperature control is monitored by “fuzzy logic” technology - relevance to each other.
• All operation and temperature control is with user-friendly push buttons.
• Improvements have been made to the rear convex section for clean-cut design.
• If a problem occurs or service is required, an error coded message appears on the digital display to
direct the service technician to the cause of the problem.
• Information about any previous faults is stored in the PCB and can be recalled during servicing.
About the 308FTR
The bodywork is formed from 0.6 mm galvanised steel sheet, which forms a box to which the components,
heat exchangers and blowers are attached. This is then covered by an outer case which is constructed from
0.6 mm galvanised steel sheet, and plastic mouldings.
The combustion chamber is constructed from 1.0 mm hot dip aluminium coated steel sheet, located in the
lower centre of the appliance.
The heat exchanger is composed of two sub-heat exchanger sets. The left hand set, No1 is constructed of
1.0 mm aluminised steel. The right hand set, No2 is constructed of 0.8 mm stainless steel. The inlet of subheat exchanger No1 is connected to the outlet of the combustion chamber, the outlet is connected to subheat exchanger N o2. Sub-heat exchanger No2 consists of 3 “sub” sections, constructed from 0.8 mm
stainless steel. The outlet of sub-heat exchanger N o2 is constructed from 0.5 mm stainless steel and
connected to the flue by a concertina stainless steel tube.
The combustion air fan draws combustion air from the outside atmosphere through the flue manifold pipe.
Air is then blown into the combustion chamber via a rubber tube. Combustion products in the combustion
chamber are pushed out into sub-heat exchanger No1, to sub-heat exchanger No2, and then into the 34 mm
flue pipe which is connected through the flue manifold to the outside atmosphere.
The flue system is connected with stainless steel concentric pipe. The inner pipe (34 mm diameter.) is the
combustion gas outlet, and is connected to the outlet of sub-heat exchanger No2. The outer pipe (70 mm
diameter) is the combustion air inlet and is connected to the inlet of the combustion fan air pipe. Various
flue lengths are available.
Ignition is continuous spark in conjunction with an electrically operated solenoid and control is monitored
by the PCB. Gas passes through the R½ 15 (BSP) inlet fitting, then via a flange connection to the solenoid
valves No1, N o2, a regulator modulating valve, aluminium injector manifold, before entering the burner.

9. Operating Principles
1. Normal Operation
Push the ON/OFF Button to operate the appliance. The Power ON/Combustion Indicator will glow green.
The combustion fan will run on high until pre-purge is completed.
Pre-purge is completed after approximately 15 seconds, following which, the combustion fan will decrease
revolutions to enable ignition to occur. After the combustion fan reaches a pre-determined speed,
(depending on gas type) the electrode produces the spark to begin the ignition cycle.
After the spark is sensed as having crossed the spark gap by the PCB, the solenoids (SV1 & SV2) as well
as the modulating valve will open and allow gas to flow to the burner.
The flame rod senses the flame on the main burner. After the flame is sensed, the Power ON/Combustion
Indicator changes to red and the spark stops. After an additional 15 seconds the convection fan begins to
operate.
The room temperature is sensed by the temperature thermistor located at the rear of the appliance. The
printed circuit board controls the air/gas ratio to the optimum level according to the selected temperature.
The combustion fan is adjusted in conjunction with the opening degree of the modulating valve. The
convection fan is adjusted in the same manner.
2. Thermostat Control
The selected and room temperatures are displayed on the Time/Temp Display. Time and temperature are
displayed alternately depending whether the heater is running or not. The selected temperature is altered by
pressing the Time/Temperature Adjustment buttons.
3. Turning Off
Simply press the ON/OFF Button. The solenoids, together with the modulating valve will close. The
combustion fan will also stop, and all indicators will go out. After the burner extinguishes, the convection
fan will continue to run for up to 210 seconds, ensuring the appliance is cool.
4. Economy Mode
To engage the economy function press the Economy button while the heater is operational. The Economy
Indicator will glow. Once the selected temperature has been reached, the economy function is designed to
drop this temperature by a total of 2oC over a period of one hour. After 30 minutes the temperature will be
reduced by 1 oC. After a further 30 minutes the temperature will be reduced by another 1oC. This does not
result in a loss to the heating effectiveness, and is an energy saving feature. You may press the Economy
button again at any time, to cancel the economy function.
5. Child Lock
To activate the child lock press the Child Lock button. The Lock Indicator will glow.
If the child lock is activated during normal operation, then no functions other than the ON/OFF Button will
be operable until the lock is released.
If the child lock is activated whilst the appliance is OFF, then the complete range of functions will be
locked.

6. Filter Indicator
When the air filter becomes covered in dust and the temperature inside the appliance rises, the Filter
Indicator will glow.
7. Fuzzy Logic
a. The Purpose of Auto Comfort [Fuzzy Logic]
The main aim of the Auto Comfort function is to heat a room by controlling the flow of the warm air coming
from the heater. This increases heating efficiency as well as improving control over the flow of warm air
being discharged by the appliance.
In order to achieve comfortable heating, it is preferable to avoid cold drafts or draughts from the appliance.
Also, for increased efficiency it is important to reduce overheating in the room and concentrate heating in
the area where people are most often situated.
Fuzzy Logic is used in order to achieve the following improved heating pattern.
Standard Control
Fuzzy Control
'Room temperature' and 'the time elapsed since the start of combustion’ are the basis for fuzzy logic. Th
means of control is the speed of the convection fan and modulation of gas combustion.
b. Fuzzy Logic Summarised
In the case of a conventional fan heater, the convection fan operates normally from the time of ignition, and
a cold draught may accompany the flow of air from the appliance. To solve this problem, fuzzy logic
controls the speed of the convection fan after taking into consideration the room temperature at the time of
ignition. For example, in the case of the room temperature being low, the fan is made to rotate at a low
speed, raising the discharge air temperature. As the room temperature rises, the speed of the convection
fan is gradually increased. In this way it is possible to ensure a comfortable volume of warmed air whilst
decreasing the possibility of cold draughts immediately after ignition.
The fan speed increases proportionally as time passes and the room gradually heats up. This improves the
warm air distribution, assisting in a reduction of stratification throughout the room and resulting in more
effective heating conditions. The PCB then continually monitors the room temperature, and adjusts the fan
speed according to the conditions at the time.
8. Clock and Timer Setting and Operation
Refer to “Appendix” on pa ge59 of this manual.
9. Intelligent Timer [Pre Heat]
This function enables the room to be heated to the pre-set temperature prior to the time programmed in the
On Timer. See Intelligent Timer [Pre-heat]” on pa ge14 for more information.
Energysaver RHFE-308 FTR
- 13 -
©Rinnai
10. Intelligent Timer [Pre-heat]
The Intelligent 2-way 24-hour programmed dual digital Timer [Pre-Heat] function operates in
conjunction with either “On-Timer”. It enables the pre-set temperature to be reached by the time
programmed by starting ignition up to an hour before the time programmed to start heating.
The actual ignition time is calculated using the difference between the room temperature and set
temperature and the warming-up time which elapsed the last time the appliance was used. The
maximum time ignition will precede the pre-set time is 1 hour. The following chart illustrates how
the intelligent timer operates.
The two timers can be programmed and used individually, or sequentially. Timer operation, once
set, will remain on stand-by for the next day after the final OFF sequence, unless ON/OFF switch is
pressed.

10. Overheat Control Method
The overheat thermistor activates the overheat sensor and the filter indicator, as well as increasing the fan
rpm.
(A) Overheat Sensor
The overheat thermistor activates at different temperatures for different gas rates (combustion).
(B) Filter Indicator
Note 1:
Once the overheat limit temperature has been sensed and the filter indicator begins flashing, it
will not go out, even if the temperature falls below the limit.
Note 2:
Once the filter indicator begins flashing, gas input is limited to roughly 88% of high combustion.

(C) Convection Fan RPM Increas
The fan rpm increases to compensate for a reduction in air flow due to a clogged air filter or other causes.
The convection fan rpm is normally determined by combustion level. The speed increases by
approximately 100 rpm at High.

17. E2 PROM
Memory Function for Error History, Estimated Combustion Time, and
Estimated Number of Operations
E2 PROM (Electrically Eraseable and Programmable Read Only Memory) is a ROM in which data
is electronically programmed or erased. Programmed data will be stored semi-permanently even if
the power fails or is disconnected.
The most recent data on the past nine errors, estimated combustion time and estimated number of
operations are included in the information stored in E2 PROM.
• How to Read the Data
Confirm the unit is off, press “/\”, “\/” and “Economy” buttons at the same time for at
least 2.5 seconds (a beep will be heard once). The data will be displayed on the LED display in the following order: Error Messages, Estimated Combustion Time, Estimated
Number of Operations.
• Data Display
The most recent error message (No. 1) will be displayed first, then it will be followed by
up to eight previous errors (No. 2~9) displayed for 2 seconds each, as shown below. Following this, Estimated Combustion Time and Estimated Number of Operations data will
be displayed for 4 seconds each as in the example below (No error messages “-- . --” will
be displayed if no errors were recorded).
Estimated Combustion Time will be displayed as below if between 0 ~ 9,999 hours. However, if it
is more than 10,000 hours, then “H” is added to the beginning of the display. Hours will be rounded
up to the nearest 100 as shown below.
9999 hours
10000~10099 hours
10100~10199 hours
Estimated Number of Operations will be displayed as below (1=10 times) if between 10 ~ 99,999
times. However, if it is more than 100,000 times, then “H” is added to the beginning of the display.
Operations will be rounded up to the nearest 1000.
99990~99999 times
100000~100999 times
101000~101999 times
*Note: Estimated Number of Operations is the number of ON-OFF movements on the solenoid
valve.

• Deleting Data from E2 PROM
Confirm the unit is turned off, and press “/\”, “\/”, “Economy” and “Lock” buttons at
the same time for at least 1 second. (Lock beep will be heard once and another beep wil
be heard a second later).
Digital display turns off and displays “- - : - -” when the data is deleted completely. However, the data on Estimated Combustion Time and Estimated Number of Operations
cannot be deleted.
Once recorded in E2 PROM, the data is protected from power failures.

Before contacting Rinnai, please check the following points. These points are part of the normal operation of the unit.
At Ignition
Is the heater plugged in? Is there a power failure?
Have the fuse or breaker blown at the switchboard?
Are the air filter, flue, or warm air outlet blocked?
Are Timers set? Clear Timers and operate again.
Is the central timer on? (where fitted)
Heater does not operate.
Warm air does not flow when the burner lights.
The fan is started automatically after a short delay.
This is to allow the heat exchanger to warm up.
Smoke or strange smells are produced on the first trial
light up after installation.
This is caused by grease or oil and dust on the heat
exchanger and will stop after a short time.
Sharp clicking noises at ignition, or when the unit cuts
down on the thermostat, or goes out.
This is simply expansion noise from the heat exchanger.
During Combustion
Clunking noise when the thermostat operates.
This is the sound of the solenoid gas valves.
Unit is not heating room?
Is the air filter or warm air outlet blocked?
Is the set temperature high enough?
Are the doors and windows of the room closed?
Air filter or louvres are blocked or obstructed.
Allow heater to cool, clean air filter, operate again.
Heater will not reignite after overheating.
Heater does not reignite. Repair is necessary.
When the Unit is Turned Off
Convection fan continues to run after turning off.
This is to remove the residual heat from the heat exchanger,
the fan will stop when the heater cools down.
Other Points
Steam is discharged from the flue terminal.
High efficiency appliances tend to discharge water vapour
on cold days, this is normal.
Unit cuts off without apparent reason.
Check is central timer is switched off (where fitted), or
whether filters are blocked, (dirty filters will cause the
heater to overheat).
Power failure.
When power is restored, the appliance will begin to heat if it
was on at the time of power failure. Clock will be delayed by
the length of the power failure.
Remote control does not operate.
Check battery. Try moving closer to the heater.

22. Testing
Test Mode Summary
Test Mode 1 -
This mode cancels temperature control, and starts combustion mode.
Test Mode 2 -
This mode controls the modulating valve and convection fan (Normally, this test
mode is used when converting gas type and changing the PCB).
* Operating Procedures and Indicator
(A) Test Mode 1
Operating Procedures
Illuminated Indicators
1. Turn the appliance on (combustion indicator illuminates). LOW
Press test mode switch (SW 5) at top of the PCB (combustion
mode changes to “Low” test mode).
2. Change combustion and convection fan mode using the MEDIUM
Temperature/Time setting switch located on the control
panel.

(SW 5) again.
Note: Indicators (digital display “00" and “22", “24", “26" and “HIGH” indicators) show that
modulating valve and/or convection fan adjustment is complete.
Digital Display
Sections of the digital display show that the
following adjustments have been completed:
1) Modulating Valve (LOW)
2) Modulating Valve (HIGH)
3) Convection Fan (LOW)
4) Convection Fan (HIGH)
The indicators will be off when the PCB unit is replaced.
Indicators will illuminate after test mode 2 adjustment is completed.
2. Indicators (digital display “LO”, “Cu”, “Hi” and “LO”, “16", “18", “20" indicators) may be flashing
at times. This means the combustion mode is in transition (eg. Changing from LOW → MED). The
indicators will glow steadily once combustion mode stabilises.
(B) Test Mode 2 (Adjusting Modulating Valve)
See “Gas Pressure Setting Procedure” on pag e43.

(C) Test Mode 2 (Adjusting Convection Fan rpm)
Convection fan rpm is prerecorded in the PCB unit software. Therefore, adjustment is not required
when the PCB unit is replaced.
Operating Procedure
Indicators
1. Turn the appliance on (combustion indicator
illuminates). Press test mode switch (SW 5) at the
top of the PCB (combustion mode changes to
“LO” Test mode).
2. Press convection fan adjusting switch LO (SW).
Sections of the indicators will flash to show that
adjustment is in progress.
3. Adjust by using the Temperature/Time setting SW
located above the control panel. “/\” SW increases
and “\/” decreases the rpm.
4. Once the adjustment is complete, press SW2 again.
