I - COMMISSIONING

1 - PROTECTION OF THE INSTALLATION

Note : Our technical personnel, who will visit when the boiler has been installed to arrange for its final

commissioning and calibration, do not perform the role of inspector and/or approval officer for the system. Its compliance with standards and instructions remains the exclusive responsibility of the installation company.

Geminox insists the use of the following heating system water conditioning products:

- BIONIBAL corrosion inhibitor (or equivalent products),

- BIONIBAGEL antifreeze and corrosion inhibitor (or equivalent products).

BIONIBAL

1.1 - Bionibal 1.2 - Bionibagel

is a biocide, traceable corrosion inhibitor specially designed to protect multi-metal heating circuits. Through its efficient means of acting against all types of corrosion and all types of bacteria, BIONIBAL:

- Prevents the formation of rust and metallic slud-

ge,

- Prevents the formation of algae and bacteria

sludge,

- Also suitable for under-floor heating systems,

- Prevents hydrogen build up,

- Contains an internal marker so that doses can be

easily controlled.

BIONIBAL DOSAGE:

- Without under-floor heating: or connection using

reinforced polyethylene type pipes: 1% (0.5 l of BIONIBAL for 50 l of water).

- With under-floor heating or radiators connected in

reinforced polyethylene type pipes: 2% (1 l of BIONIBAL for 50 l of water).

BIONIBAGEL

BAL. Antifreeze, with glycol monopropylene base, corrosion inhibitor, biocide, traceable. In addition to the characteristics of BIONIBAL, it protects the installation from frost for residences that are not inhabited all the year round or that are in the coldest regions.

BIONIBAGEL DOSAGE:

The number of litres of BIONIBAGEL to put in the circuit depends on the volume of your installation and the extreme temperature of your region.

Important warning

Bionibal or Bionibagel must only be put in a clean installation that has been checked. It is therefore imperative to fill the entire system one or more times with clean water as required. In

some cases, the system may need washing by a suitable product:

Example:

- In a new installation: To detect any leaks and eliminate any traces of welding, weld solder or other residues.

- On an old installation: To eliminate any trace of sludge and other products in the radiators, under-floor heating system and the boiler.

Bionibal or Bionibagel will not clean dirt or corrosion left behind from the installation, it is not sufficient to believe that adding our chemicals will clean the system. The system should be clean and then our chemicals will keep it clean.

COMMISSIONING

- The installation will have to be rinsed before the boiler is filled with water.

- To ensure proper boiler bleeding during the installation’s filling stage:

• Filling the DHW tank for the THI 10-50 C mo-

dels + DHW production system: . Fill the tank with water by using the safety

control box of the installation, taking care to open a hot water tap,

. After filling, check that the tank access flap

is tightened correctly.

• Filling the installation :

. Open the heating flow/return isolation val-

ves,

3 - GAS SUPPLY

- Open the gas cock (item. 2, fig. 43 to fig. 45 page 41 to page 42- chapter IV - INSTALLATION

- SERVICING MANUAL).

- Carefully bleed the gas piping. If the installation is new, the bleed evacuates the air that is contained in the piping so that the boiler has an adequate fuel.

The presence of air in the gas prevents the ignition of the burner and leads to safety shut-down by the flame monitoring unit.

. Open the cold water inlet valve, . Fill the installation slowly (to make degas-

sing easier) by using the valve of the filling

system, . check the leaktightness of the circuit, . Bleed the entire installation, particularly the

radiators. Continue to fill the system until a

pressure of approximately 1.5 bar is rea-

ched,

To read the pressure:

1) Switch on the boiler

2) Press the info key twice

3) The value of the pressure is shown on the display

. turn off the filling valve.

This is the case both with a natural gas and a LPG new installation. With a LPG installation the storage tank must also be bled properly before commissioning.

The external discharge of the gas bleed must be carried out with all ne-

cessary safety measures.

- Check the tightness of the connectors and the airtightness of the gas circuit using a foaming product or a water column pressure gauge.

4 - FLOW RATE OF THE SEP VERSION

THI 10-35 SEP is equipped with a flow limiter to pro- vide 16 l/min at 2.5 bars.

5 - SETTING THE MAXIMUM POWER IN HEATING MODE

The maximum power of the boiler in heating mode can be limited. This operation requires modification of the PHz parameter in the boiler's LMU management unit.

Access to the PHz parameter is possible via the QAA 73 ambient temperature sensor (line 541).

The PHz value should be selected by following the diagram below. Adapting the boiler's maximum heating power to the maximum power of the installation helps avoid heavy loads during reheating phases and thus reduces the maximum sound output of the boiler.

2 - MAINTENANCE

Maintenance alarms can be automatically triggered, indicating that maintenance jobs are due. The following reasons for maintenance alarms can be delivered:

- Interval of burner hours run since last regular service visit exceeded.

- Interval of the number of startups since last regular service visit exceeded.

- Number of months since last regular service visit exceeded.

The alarm displayed is always the maintenance alarm that occurred first.

There is no storage for the maintenance alarms since all pending alarms can be checked at any time via the counter readings or the relevant parameters.

2.1 - Maintenance alarm

If a maintenance alarm occurs, an error code "105 maintenance" appears on the dipslay of the boiler and / or room unit.

This code does not give precise information on maintenance but is only a general maintenance note.

2.4 - General activation of maintenance alarms

Parameter "WartungsEinstellungen" (QAA 73 setting : 630) permits or suppresses the generation of maintenance alarms.

The subdivision of parameter "WartungsEinstellungen" by bit is shown in the following table :

These maintenance alarms are a priority lower than that of the error codes to ensure the error codes prevail.

The maintenance alarm is sent until the enduser has acknowledged the message or the heating engineer has rectified the fault.

2.2 - Maintenance code

The maintenance alarm does not provide detailed information about the reason for the fault. Details can be displayed using parameter "WartungsCode" (QAA 73 setting : 726).

Le maintenance code can also be viewed on the display of the boiler (b0).

OPERATING FAULTS

2.5 - Activation of the individual maintenance alarm

Every cause can be individually activated or deactivated by entering the associated limits.

- Burner hours run :

Burner hours run maintenance is activated by setting parameter "BetrStdWartGrenz" (QAA 73 setting : 625) to a value other than "0".

This value represents the target number of hours run. When this limit is reached, a maintenance alarm will be delivered (interval since last service visit).

- Number of startups:

Startup maintenance is activated by setting parameter "InbetrSetzWartGrenze" (QAA 73 setting :

626) to a value other than "0". This value represents the target number of star-

tups. When this limit is reached, a maintenance alarm will be delivered (interval since last service visit).

- Months (service):

Service maintenance is activated by setting parameter "MonatWartGrenze" (QAA 73 setting :

627) to a value other than "0". This value represents the target number of

months. When this limit is reached, a maintenance alarm will be delivered (interval since last service unit).

Note :

- The month counter is only active when the device is connected to power.

2.6 - Acknowledgement of maintenance alarms

The acknowledgement sets the internal error code "b0" and the fault statut message to "0", but the maintenance code still gives the precise reason for the maintenance alarm.

2.6.1 - Acknowledgement via QAA 73

For the parameter "WartungsQuittierung" (QAA 73 setting : 629) (defaut value: 0), to acknowledge the maintenance alarm the heating engineer (or the enduser) enters the value of "1".

If no repetition is required, all maintenance alarms after this acknowledgement will be locked, even if other reasons for maintenance occur. In that case, parameter "WartungsQuittierung" remains constantly at 1.

2.6.2 - Activation of the repetition after acknowledgement

If required, a timer (duration of repetition) can be started, that is, the maintenance alarm will reappear on the display after a certain period of time. An acknowledgement can also be made then. This period of time starts after each acknowledgement.

The repetition can be set via parameter «WartungsRepetitionsDauer» (QAA 73 setting 633).

Contents of parameter «WartungsRepetitionsDauer» is the desired period of time (in days) until the maintenance alarm appears again.

If a value other than «0» is entered there, a repetition is made within the entered duration of the repetition time.

During this period of time, no more maintenance alarms will appear, even if

other reasons for maintenance occur.

2.7 - Resetting the maintenance alarms

Resetting can take place at any time, and after acknowledgement or during the repetition sequence.

A reset can be made in 1 of 2 ways:

- Total reset :

Here, all maintenance alarms can be reset at the same time. If, in parameter «WartungsEinstellungen» (QAA 73 setting 630), «1» is entered, all maintenance counters will be set to «0» when the parameter is saved.

The maintenance counters of the hours run, startups and months maintenance alarms will be newly started.

- Individual resert of a certain maintenance

alarm :

Individual maintenance alarms can also be reset. In that case, parameter «WartungsEinstellungen» (QAA 73 setting : 630) will again be addressed bit by bit.

There is a bit available for each maintenance alarm via which this maintenance alarm can be reset (section 2.4 - page 19 - chapter IV - OPERATING FAULTS - SERVICING MANUAL). It is thus possible to also reset other reasons for maintenance although they have not yet occurred.

When resetting the maintenance alarm, the maintenance code and the internal error code (b0) will automatically also be reset.

Note : Only the QAA 73 can the maintenance alarms

be activated, the reasons for the maintenance alarms be checked and a reset via parameter be made.
