Legionella
If the DHW cylinder has been fitted with a control sensor instead of a thermostat for increased efficiency, the control will recognise this and automatically initiate an anti-legionella function. In this case the user should be aware that once a week the
DHW set point is overridden and the cylinder is heated to 65° C for 10 minutes.
The default time for this action is monday 8am every week.
If the set point has been reduced to say 40° C for safety reasons, the users must bear in mind that the temperature around this time may be much hotter than usual.
The time of the function may be altered or the action disabled.

2.0 Introduction
2.1
Description
1. The appliance incorporates a Stirling engine which is capable of generating between 0.4 – 1.0 kW of electrical power depending on the running conditions of the heating system. High return temperatures especially above 65°C will reduce the power generation.
It is therefore in the interests of the householder to ensure that the central heating system is maintained and working as efficiently as possible. Balance the radiators in the central heating system so that there is suitable drop in temperature across each radiator. 20°C is optimum for new systems but some older radiators originally installed with non condensing appliances may only manage 11°C.
2. The use of a programmable room unit incorporating a room sensors (as apposed to a room thermostat) will also improve the power generation.
3. If the return temperature to the appliance gets too hot the engine burner will switch off to protect the engine – in this case the supplementary burner will light on its own until the return temperature has cooled sufficiently and the engine burner will be enabled again.
4. The electricity generated in this manner if not consumed directly by the user is fed back into the grid. Arrangements can be made with the electricity provider to compensate the householder by way of a feedin tariff. See section 13.3.
5. It is your responsibility to contact your electricity supplier and inform them that you have installed a Baxi Ecogen which will generate electricity. This is a legal requirement.
6. Operation and control is similar to a domestic boiler and is fully automatic.
7. All interactions with the appliance are either through the removable
Programmable Operator Unit (POU) on the front of the appliance or on a remote wall cradle.
2.2
Important Notes
1. Read and follow these instructions thoroughly before switching on and operating this appliance. These instructions must be followed and warning labels must be adhered to.
2. As with any domestic boiler, flammable materials MUST NOT be placed near this appliance and materials emitting flammable vapours must not be stored in the same room.
Do not position a kettle or toaster directly below the appliance.
3. The appliance MUST NOT be tampered with, abused or any sealed components adjusted as this may result in a hazardous situation.
4. Please note that because of the high efficiency of the appliance, condensate (water) is produced from the flue gases. A condensate
‘plume’ (water vapour) may also be seen coming out of the flue.
Gas Connection
5. Your Baxi Ecogen appliance has been installed by a Gas Safe registered installer– this is both good safe working practice and complies with the current gas safety regulations.
Electrical Connection
6. Your Baxi Ecogen appliance has been installed in accordance with the Installation Instructions, this means that:
The appliance has been earthed.
The electricity supply to the appliance is 230V ~ 50Hz.
7. Connection to the electricity supply has been made in a way that allows complete isolation of the electricity supply from the appliance.
The isolation switch is located in an accessible position within your installation.
8. It is a legal requirement that both the District Network Operator
(DNO) and the electricity provider are informed of the installation of this appliance - see section 13.3.
NOTE: In the event of a power failure the appliance will turn off automatically and will not restart for at least 3 minutes after the power supply has been restored.

3.0 The Programmers
3.1
Getting Started
1. Ensure that both gas and electricity are turned on to the appliance.
2. The Gas Safe registered installer will have set-up the appliance to a programme of your choice and it should be providing heat and hot water in line with your requirements. These can be altered via the wall-mounted room unit or the programmer on the product fascia, both of which are shown in this section. Section 4.0 and 5.0
detail how the timings and settings for your heating and hot water can be changed.
3.2
Programmable Operator Unit (POU)
1. This is located at the base of the appliance on the front cover. It displays important information about how the appliance is working and allows you to alter settings to configure the operation to your requirements.
2. It can be removed from the appliance to act as a programmable room unit (PRU) when mounted in a wall cradle accessory. This then becomes a temperature sensor and programmer.
3. If your Ecogen appliance has been installed using the existing room temperature and time controls the installer should have made sure that the appliance programs for the central heating and domestic hot water are set to 24hr operation – see sections 7.1
and 7.3 - choose ‘On’ in both cases.
4. Refer to the instructions for the existing programmers for setting the timed periods and the room temperatures. The programmable operating unit will display the boiler flow temperature and any errors see section 9 onwards.
3.3
POU as a Programmable Room Unit (PRU)
1. The Room Unit Wall Cradle accessory is available in two formats. a) Hard Wired i.e fixed to a wall, the screen illuminates upon operation.
b) Radio Frequency, cradle mounted and portable, with no permanent screen illumination.
2. The Radio Frequency unit is powered by three AA batteries located in the rear of the unit behind a slide down panel. If battery power is depleted a warning symbols appears on the display screen, replace the batteries.
3. The operation of both Radio Frequency and hard wired units is identical.
3.4
5 LED Unit
1. The 5 LED Unit is fitted when the POU is removed and gives basic information about the state of the appliance:-
1st Green Mains On
2nd Green Communication Status
1st Yellow Engine Burner On
2nd Yellow Supplementary Burner On

9.1
Exceptional conditions
1. In exceptional cases, the display will show an error screen see diagram opposite.
2. With the following information: -
An error number a short description of the error
The display may or may not show a flashing spanner, a flame crossed out or both depending on whether the unit is on the appliance or the wall.
3. Pressing the menu button will return the POU to the standard display which will now show the following symbol E which indicates that an error or fault has occurred in the appliance.
After 1 minute the display will automatically revert to the error screen.
4. Press the menu button twice to revert to the error display immediately. A list of error codes is shown in section 10.1. This list contains both user reset and automatic rest codes. Automatic codes are given here as they are capable of clearing automatically and do not necessarily indicate that a service visit is required.
9.2
Automatic reset
1. If a flashing spanner is shown on the POU the error may reset once the condition has cleared. Many of these automatic reset errors are connected with temperature sensors of both the system and the appliance and once the appliance has cooled it may restart. If the problem persists where the same error code is repeatedly displayed or the error will not clear you should call for a service engineer.
9.3
User reset
1. A user reset can only be carried out on the appliance POU not on a PRU.
2. To perform a user reset:a) on the 5 LED unit, press the reset button at the bottom of the unit, after a few seconds the red flashing LED will go out.
b) on the POU reset appears, press the dial knob twice, after a few seconds the error symbol should disappear.
3. The error will clear and the appliance will restart if there is a demand for heat as long as the error condition has cleared. The user error codes give an indication of possible problems which the user may be able to rectify such as accidental isolation of either the gas supply (error 261and 262) or the central heating circuit, pump problems etc (error 275 and 276).
4. If the error returns the fault condition is still present.
9.4
Service reset
When a flashing spanner is accompanied by a crossed out flame symbol on the appliance, a fault has occurred which requires the presence of a service engineer. When ringing the Heateam
Service Department to request a service engineer please quote the error code and accompanying message.

This is a shortened list of the error codes, which will be displayed on the Programmer or on the room unit. If more than one error is active, the one with the higher priority or the one that appeared first will be displayed.
Error codes 157,274,261,262 and 300 can be reset by the user by pressing the user reset button for 2 seconds, turning the dial to alter the flashing NO to a YES and then pressing the OK button. After a few seconds the error should clear enabling a restart of the appliance. Errors 261 and 262 may indicate a problem with the gas supply.
Errors 157,164,274 and 300 may indicate a problem with the central heating water fill or pump. If the problem persists contact the installer with the error code.
Error 158 indicates a possible blockage in the condense drain.
Error codes 10 through to 99 (except 97) are linked to installation and commissioning of your system and as such you should contact your installer to complete commissioning.
Error codes that are shown as automatic reset will disappear once the fault has cleared. The appliance will restart if there is a demand except in the case of errors 263 and 264 when the appliance must be switched off and on again to enable a restart.
All other error codes indicate a fault condition, which will require the attention of a service engineer.
