ECO 20 Automatic Regulation of Burning

1DEVICE DESCRIPTION

1.1 Basic Description

The ECO 20 is an automatic burn control device for fireplace stoves. It is not suitable for burn control

in fireplace inserts or accumulation stoves.

This product offers unique features representing the cutting edge in burn control technology for an

enhanced user experience.

•Overheating indication

•App color indicates optimal fuel quantity

•Can control 2 external devices

•Can be equipped with a second thermal sensor

•Control through mobile app

The ECO 20 is a fully autonomous control system. It is not necessary to connect the control unit to

the mobile app. Not connecting will, however, make it impossible to adjust settings and / or receive

information about the combustion process and overheat warnings.

The ECO 20 Puts an End to Overheating

Overheating is possibly the most wasteful home heating practice. It is very common to introduce more

fuel than necessary for your heating needs; this results in most of the “extra” energy from the fuel

escaping uselessly through the chimney. Aside from wasting fuel, this also significantly increases wear

on the heating system, including the chimney.

The ECO 20 can detect overheating and inform the user to add less fuel in the next refueling.

The mobile app informs the user about the current status throughout the entire burn process. Based

on the current firebox temperature, the app displays 3 color indicators (yellow, green, red).

The user should adjust the fuel amount so that when the firebox is at maximum temperature, the

app shows the green indicator. Once the current burn has progressed sufficiently, the app evaluates

the adequacy of the fuel load used by displaying a colored dot in the top left corner of the app

screen:

-yellow: fuel load was less than optimal

-green: fuel load was optimal

-red: fuel load was more than optimal (overheating)

1.2 General Information

Most fireplace stove manufacturers recommend using the air intake shutter to control the amount of

air in the firebox, using the 100% –50% –0% positions. Start the fire with the shutter fully open,

close it to one half when the firebox reaches maximum burn, and close it completely when only coals

are left. This improves both the environmental and economic performance of the heating system: A

fuel load lasts longer, heating is more efficient, and the energy left in hot coals is not lost through the

chimney.

This approach does have an obvious problem: The user would have to continually mind the stove to

keep adjusting the shutter at the right times. Automatic regulation systems address this problem, as

they monitor the exhaust temperature and automatically adjust the shutter position in response.

ECO 20 Automatic Regulation of Burning

The automatic regulation system has its own shutter mounted on the external air intake (EAI) flange

or inside the flexible air intake hose. All modern stoves have a compatible EAI flange, usually with

diameter 100 mm or 120 mm.

The automatic regulation then serves as the “brains” of your heating system, managing airflow to the

firebox to maximize burn efficiency and extract as much useful thermal energy from your fuel as

possible.

The Timpex system for automatic regulation of burning has a microprocessor-based control unit,

which compares the current situation in the firebox with a “Combustion Optimization” program;

depending on the results, the system adjusts the airflow to the firebox using an electronically-

controlled motorized shutter in the external air intake.

1.3 Advantages of Automatic regulation of burning

•Increases burn time and refueling interval

•Improves fuel economy by up to 30%

•Prevents overheating

•Improves burning and heating efficiency

•Increases thermal comfort

•Enhances safety of heating

4INSTALLING THE MOBILE APP

4.1 Downloading the Mobile App

The mobile app is available on the Google Play Store and the Apple App Store; the app name is

Timpex ECO. Open the app details in the store and tap “Install”; the app will then be automatically

installed on your phone.

4.2 Pairing the App with the ECO 20 Control Unit

1. Turn on Bluetooth and GPS positioning on your device.

2. Launch the mobile app.

3. The app will need permission to access your device’s location. This is necessary because the

app searches for your specific ECO 20 control unit only near your position.

4. Once launched, the app starts an automatic search for nearby ECO 20 devices. Once the

search completes, the app will show a list of units found. Select the one called Timpex_ECO.

5. The app will then request a pairing password. Enter the default password 123456 and press

OK to confirm.

Note: If the app failed to request a pairing password, check your phone’s notification bar.

Some Android devices move the password request and entry to a notification item.

6. The mobile app is now paired with the ECO 20 device.

Note: The ECO 20 can only be paired with a single mobile device at a time. If you wish to connect

another mobile device, you will need to disconnect the current one first.

5MOBILE APP DOCUMENTATION

5.1 Main Screen

Background color

The app background alternates between four colors based on current firebox temperature:

•yellow - firebox temperature below optimum

- should only show when starting a fire or when down to hot coals

•green - firebox at optimum temperature

- best fuel efficiency –shows a green leaf icon

•red - firebox overheated

- excess energy lost via chimney –shows a chimney icon

Grey colour means cold firebox (firebox at room temperature, no fire).

ECO 20 Automatic Regulation of Burning

The Settings menu is password-protected; the default password is 1234.

Contents

•Program setting

-Allows you to select one of a number of pre-set control curves, each of which

maps exhaust temperature to shutter position in a different way. The factory

setting is no. 3, which should work well with most fireboxes.

-If your firebox generally burns too hot using program 3, step down to program 2 or

further down to 1.

-If the firebox generally burns too cool, raise the setting to program 4 or 5.

•Software door sensor /SDS/

-The SDS bypasses the need to push START in the app when beginning a new burn

cycle.

-The SDS is a software algorithm that monitors the changes of current exhaust

temperature, from which it can infer that fuel was added and / or the firebox door

was opened, and start a new burn control cycle accordingly.

-When using the SDS feature to auto-start the burn cycle, keep the firebox door

slightly open after refueling until the control unit sounds an alert (3 short beeps).

-The sensitivity of the SDS algorithm to temperature changes can be calibrated in

steps from 1 to 5.

oThe factory default setting is 3.

oIf you would like the SDS to be more sensitive to temperature changes,

increase the value to 2 or further up to 1.

oIf you want the SDS to be less sensitive, lower the value to 4 or 5.

•Test

-Test the functionality of the automatic regulation system. Click an item to test EAI

shutter open / close, sound alerts, relay contacts on / off, and (when installed)

color LED function.
