Seguin Autopilotihs User manual

User manual

for FIREBOXES

IHS system stands for "Intelligent Heating System", it regulates the

combustion in your new firebox. The purpose of the Autopilot IHS™ is to

provide greener, more economic combustion for the environment, which

is more comfortable for you.

Autopilot IHS™ is the product of a brand new patented technology that

adjusts the volume of combustion air in the firebox. Your new firebox

regularly measures the temperature and oxygen content of the gases

and is programmed to have an optimum oxygen supply through 2 major

air inlets. The remote control is used to set the required temperature

and displays the room temperature, it makes it possible to optimise

combustion in terms of the environment and cost.

Your new Autopilot IHS™ automatically controlled firebox guarantees the

cleanest and most economic wood combustion, whatever type of wood

is used, whatever the chimney, whatever your experience or any other

factors.

Components of the Autopilot IHS™ automated system:

- Airbox: the Airbox contains a circuit board/software and 2 motors

that manage the primary and secondary combustion air. The fresh

air supply must be connected to the Airbox, either at the back or

underneath.

- 2 sensors: a temperature sensor and an oxygen analyser send their

data to the Airbox.

- Remote control with a wall holder: place the remote control

(remember to insert batteries) 2 metres away from the firebox. The

remote control measures the room temperature and sends its data

directly to the Airbox.

- Electricity supply: from the Airbox to the closest power outlet.

Assembly and installation guide

Statutory requirements

Make sure you comply with statutory and technical requirements when

you install your SEGUIN DUTERIEZ firebox. Ask your SEGUIN DUTERIEZ

reseller for advice on assembling your firebox.

Connecting and preparing the Autopilot IHS™

1. Connect

a) To a standard 230V power outlet

b) A mark on the Airbox shows where to plug in the socket. Refer to

our photos of the Airbox connection.

Airbox without an electric connection Airbox with an electric connection

2. Install 3 AA batteries in the remote control. When the IHS logo is no

longer displayed on the screen, the remote control is ready to use.

3. The remote control and the firebox must be linked (link configured in

our factory)

If the line at the bottom of the screen is blank ( )

and divided into three parts, the firebox and remote control are linked.

If the status line shows dashes, the firebox and the remote control are

not linked ( ). Make the link (when the screen is

not lit) by pressing on the button until the advanced menu is displayed.

Press the button several times until you find "Link to firebox". Highlight it

and wait for it to show on the menu. Briefly press the button until you find

"Connect", highlight it and wait again. Once the screen displays "Please

cycle firebox power", power off the Airbox for 3 seconds and then power

it back on. Press the button again. If "Connected to firebox" is displayed

on the screen, the firebox and the remote control are linked. Pressing the

button again returns you to the main menu. If you do not press the button

again, the remote control exits from the menu automatically and returns

to the initial display.

4. Run the Autopilot IHS™ self test.

The electronic control self test is carried out before lighting the firebox

for the first time (carried out in our factory). The self test is not run

until the firebox is cold and on standby ( ) (status

line not shown).

Make sure that the display is not active, i.e. that it is not lit

(). If the screen lights before a long press on the

button, the firebox is preparing itself for lighting (matchbox on the screen)

and the self test cannot be run. Press on the remote control button for

about 5 seconds to display the menu. Press the button until "Selftest" is

displayed. Wait for a few seconds until the remote control displays the

"Selftest" menu. Press the button until "Engage" is displayed. The self test

starts within a few seconds.

Running the self test guarantees that all the basic functions are in working

order.

The Self test is composed of four types of test:

- Software test

- Temperature sensor test and calibration if necessary.

CAUTION: CORRECTLY SIZED ACCESS HATCHES ARE

MANDATORY FOR MAINTENANCE

(top part for the sensors + bottom part for the Airbox)

- Oxygen analyser test and calibration if necessary

- Test of the two motor dampers and calibration if necessary.

The remote control indicates "Pass" if everything is correct, and "Failed"

when there is a problem. The "Failed" message may also be displayed if

you have prepared the firebox for lighting (matchbox on the dial) before

the self test. If you power off and then back on again, the programme

switches to standby mode and the self test is run. The "Not completed"

message on the screen indicates that the self test was not able to complete

because the firebox is not completely cool, and is not in standby mode.

5. The remote control must be in the same room as the firebox but not

directly exposed to the firebox's heat or to direct sunlight. In fact, the

remote control also acts as a thermometer. The room temperature,

which is directly sent to the electronic firebox controller, contributes to

the smart combustion regulation. You can fix the holder provided with

the remote control to a wall.

The chimney

The chimney draws because of the temperature difference between the

inside and outside of the chimney. The higher the temperature inside

the chimney, the more it will draw. A masonry chimney takes longer to

heat than a steel chimney. If the chimney is not drawing properly due to

weather conditions it is essential to warm up the chimney as quickly as

possible. This means obtaining flames quickly. Use very thin split wood

or use an extra firelighter.

In the event of a chimney fire or of overheating, Autopilot IHS™ places

the system in safety mode and automatically adjusts all the dampers to

put the fire out quickly. Do not open the door to avoid restarting the fire.

Call the fire brigade. Before using the firebox again ask a chimney sweep

to check the chimney.

Remote control

The remote control is the Autopilot IHSTM. user interface.

The remote control permanently measures the room

temperature. Place it away from strong heat sources such

as the direct heat from the firebox or direct sunlight.

Set the required temperature on the remote control in

the same way as on a radiator thermostat. The remote

control emits room temperature data and the required

temperature to the firebox airbox (controlling system)

using radio waves.

The remote control functions are described below. The

normal remote control display shows 4 basic items:

1) The room temperature

2) The remote control battery charge level

3) The thermostat setting (required temperature)

4) The status line (indicates the combustion steps)

Button:

Long press - only when the screen is not lit = advanced

Short press - during the start up or combustion phases =

thermostat regulation (required heating value)

Short press - in standby or in the combustion phase =

starting up the firebox, i.e. preparing the firebox to be lit.

Symbol description

IHS IHS Logo

Appears as soon as you turn on the remote control,

for example when you have just replaced the

batteries.

21°C Room temperature

The room temperature is displayed at the centre

of the screen. The surrounding temperature is

measured where the remote control is located. The

room temperature measurement is used to drive the

combustion and manage the alarm indicating that

firewood should be added. Do not place the remote

control near the firebox or in direct sunlight in order

not to have incorrect room temperature data.

Battery level

Remote control battery charge level. When the

batteries are at the minimum level they must be

replaced. The normal battery life is from six months

to one year.

Thermostat setting

The Autopilot IHSTM maintains room temperature

at the required value. The thermostat operates just

like a radiator. Use the remote control to choose the

required heating depending on the room size and

other parameters. The thermostat has six settings:

(Level 0 - 5 where level 3 is an average of 22-24°C).

Level 0: Combustion regulated to its lowest level

(3-4 kW), no room temperature management

Level 1 -2: Room temperature regulation, low level

(about 18-22°C)

Level 3: Room temperature regulation, medium

level (about 22-24°C)

Level 4: Room temperature regulation, high level

(about 24-26°C)

Level 5: Room temperature maximum regulation

(about 27-29°C) Level 5 is used to reach the highest

possible room temperature as quickly as possible,

recommended if you want to heat a cold room

quickly. Once the room temperature comes close to

the required value, choose the required value on the

remote control.

Status line

The status line is at the bottom of the screen. It

indicates the system's combustion status.

No contact with the airbox.

In contact - but on standby.

Initial combustion phase.

Combustion operating phase.

Final combustion phase.

20° C

Lighting the fire:

The firebox is ready to light a fire and the flaps open.

This symbol appears by pressing the remote control

twice in standby mode or in final combustion mode.

This symbol is also displayed in the combustion

phase if you press the remote control twice. In this

case it does not mean you want to re-light, but that

you have requested the opening of the firebox flaps

to ignite the wood quickly.

Fire fuel supply alarm

As soon as the combustion produces embers, the

alarm warns of the need to feed the fire. The alarm

is triggered three times at 10 second intervals

accompanied by a sound signal.

Wood supply, three possible levels:

Small quantity (700 – 1 200 g)

Medium quantity (1,000 - 2,000 g)

Large quantity (1,800 - 3,000 g)

Always add two logs at a time, even when only

adding a small quantity. The temperature ignites

the wood. 2 logs retain the heat better and their

temperature rises faster.

Reminder of the fire feeding alarm

If a fire feeding alarm has triggered and the fire has

not been fed, this symbol displays at the top right

corner.

If the symbol has been displayed for a long time,

the gas temperature may be so low that the fire may

have to be re-lit to bring enough combustion air

into the firebox (to do this, press the remote control

twice to display the lighting symbol on the dial).

After having fed the fire, make sure the status line

passes from the combustion to the running phase.

You thereby make sure that the firebox has recorded

the new supply of logs and that the combustion has

the correct air supply. The firebox records the wood

supply when the oxygen level increases due to the

door being opened. At the end of the combustion

phase, the oxygen level in the combustion chamber

and that of the room may be so close to each other

that the opening of the door does not result in an

increased oxygen level. If the status line does not

pass from the combustion to the running phase

soon after the fire has been fed, press on the

remote control twice to display the lighting symbol

(matchbox).

Updating Refresh

Each time the Airbox is refreshed (by a technician),

this symbol is displayed.

Advanced menu

The remote control has a menu from which you

can change the advanced settings. Press the

remote control button for 5 seconds to display the

advanced menu:

Main menus:

- Sound (activated or mute)

- Self test (to launch the self test, for example after

a refresh by the technical department)

- System information (Airbox and remote control

software versions)

- Link to firebox (useful to link the remote control

with the Airbox, carried out in our workshops).

Servicing alarms

If a servicing alarm is triggered you can continue

lighting the firebox but you should contact your

distributor as quickly as possible. Remember to

indicate the error code displayed on the screen.

Your firebox may be burning incorrectly.

Safety alarms

If a safety alarm is triggered, do not light your

firebox. Contact your distributor as quickly as

possible. Remember to indicate the error code

displayed on the screen

Disposal and salvage

When you dispose of the remote control batteries, do not put them in the

household waste, and comply with national regulations.

Regulatory compliance

Compliant with European Directives 72/23/EEC and 2004/108/EEC.

Thermostat operation

A a starting point the Autopilot IHS™ provides optimum combustion

for the environment and adapts to the required room temperature. The

thermostat operates similarly to a radiator thermostat. Set the required

temperature for the room in which the firebox is installed. Once the

thermostat is set to the required temperature, the control adapts to the

target temperature as far as is possible.

When the room temperature is lower than the required temperature, the

control raises the gas temperature in order to increase the firebox's heat

emission.

When the room temperature is higher than the required temperature,

the control lowers the gas temperature to keep the embers alive as long

as possible before feeding the fire. This is to reduce the firebox's heat

emission, but also to allow the fire to be fed without re-lighting it. If the room

temperature drops below the required temperature, the ember phase is

shortened and the system triggers a fire feeding alarm. The system triggers

a fire feeding alarm as soon as the gas temperature is around 180°C; at

100°C the system switches to standby position and all the dampers close.

If the room temperature is significantly lower than the required level, the

control increases the gas temperature. If this temperature increase is not

sufficient, the control triggers a fire feeding alarm while awaiting a new

load of wood to reach the required temperature in the room.

If, after the fire has been fed, the temperature is still not high enough, this

may be due to the wood being damp or the chimney not drawing enough.

The gas temperature must always be at least 350°C in order to protect

the environment.

Feeding the fire

When the fire feeding alarm triggers, the firebox is ready for more wood.

The remote control recommends how much wood to add.

Small quantity of wood (700 - 1200 g)

Medium quantity of wood (1000 - 2000 g)

Large quantity of wood (1800 - 3000 g)

For combustion, always feed at least two logs at a time, even if you only

add a small quantity of wood. You can also decide not to feed the fire. The

fire will go out automatically after a certain period of time.

In some rare cases, the system does not record the new logs. For example

when the oxygen level in the combustion chamber is so high, due to the low

gas temperature, that it fails to record the increased oxygen level despite

the doors being open. Each time you add wood, check the status line on the

remote control. A short time after wood is added, the line lights at the centre

(), in the box that indicates the combustion

phase. If combustion is on standby, press the remote control twice to

display the matchbox.

General

To get the best possible combustion

Autopilot IHS™ is designed to guarantee the cleanest and most economic

combustion possible. To achieve good combustion the fire must receive

the correct volume of oxygen at the correct location in the combustion

chamber at the right time. The Autopilot IHS™ takes into account variable

external factors, but it is important to burn clean, dry wood.

Types of fuel

The firebox can suffer damage at high temperatures, for example the

whitening of the window. To avoid this, also close the ash box during

combustion. Also be very careful when using a fuel that emits a large

amount of heat, such as wood blocks for example. If the gas temperature

exceeds 580°C, Autopilot IHS™ switches to the safety position and

automatically closes the air damper to avoid overheating. As soon as the

temperature falls back to 450°C, normal combustion resumes.

Recommendations for lighting a

firebox fitted with the IHS system

The so-called "reversed lighting" method makes it possible to start up

gradually while reducing the formation of gases.

Check before lighting: The ash box grate must not be obstructed by ash,

(the 9 air passages must be clear)

Place the wood on 3 levels:

Level 1: 4 crossed rows of 3 or 4 small logs (10 to 12 cm² cross section)

Level 2: 3 to 4 rows of 3 or 4 even smaller logs (6 to 8 cm²) + place the

firelighter on the top

Level 3: Place some easily inflammable kindling

NB: Crossing the logs allows gradual ignition in order to avoid

condensation phenomena (formation of "tar" on the window)

- Open the damper:

- Open the ashbox air slide:

- Press the remote control twice: The "matchbox" lighting symbol is

displayed, you then have about ten minutes to light the firebox

- Light the firelighter

- The firebox door can be left ajar for a few minutes to encourage the

starting phase.

CAUTION: Check that there is no smoke, otherwise keep the door closed

- When the complete load has ignited

- Gradually close the damper:

- Gradually close the ashbox:

CAUTION: OUTSIDE THE STARTING PHASE, THE

AIR FLAP ON THE ASHBOX DOOR SHOULD ALWAYS

REMAIN CLOSED

Reloading once the firebox is running:

- About twenty minutes after lighting the firebox, the remote control will

indicate that fuel needs to be added.

Fuel can also be added earlier if ignition is complete and the bed of

embers is even

- Open the damper

- Refuel by spacing the logs a few centimetres apart so that the flames

can engulf them evenly

To encourage correct ignition, always add fuel to an even bed of embers

- Close the damper

- Follow the instructions on the remote control for the successive statuses
