3.3 Adjusting the boiler to the system

The boiler's control unit is set to the most common central heating systems. With these settings, practically all central heating systems will work well. However, the user or the installer can optimise the parameters as he/she wishes.

3.3.1 Changing parameters at user level (without access code)

The following settings can be changed at user level:

= Maximum flow temperature [^], adjustable between 20 and 90^;

P 2 = Pump post-circulation time 0..98 mins, 99 is continuous; P 3 = Boiler control; central heating on/off.

0 = Central heating off

1 = Central heating on (= factory setting)

P 4 = Display

0 = Simple display

1 = Comprehensive display

2 = Display automatically goes to simple after three minutes (factory setting)

The parameters can be changed at user level as follows:

1. Press the ⏻ -key several times until the 🔔 symbol flashes in the menu bar;
2. Select the users menu using the ← -key, P: I appears (the / flashes);
3. Press the [+] -key; P:2 appears (the 2 flashes);
4. Press the ← -key again; 3 (min) appears and flashes: (factory setting);
5. Change the value by pressing the [-] -key or the [+] -key, in this case for example to 15 min, with the [-] -key;
6. Confirm the value with the ← -key, P2 appears (the 2 flashes);
7. Press the ←- key twice, the boiler enters the current operating status.

The P1 to P4 settings can be changed in the same way as P2.

In some cases, it may be necessary to set the boiler to manual operation, for example when the controller has not yet been connected. The boiler can be set to automatic or manual operation under the 🔊 symbol. Do this as follows:

• Press the ⏻ -key several times until the 🔊 symbol flashes in the menu bar;
• Press the -key once, either the minimum flow temperature or R U E O (only if an external sensor has been connected) will appear in the display; the flow temperature is determined by the internal heating curve;
• Press the [+] -key to increase this value in manual operation temporarily;
• Confirm with the ← -key;
  • The boiler is now set to manual operation;
• Press the ←→ -key twice to exit manual operation; the boiler enters operating status.

Manual operation keeps active after power breakdown.
fig. 04 Setting manual operation

3.5 Taking the boiler out of operation

The boiler must be switched off for maintenance or repair work. If the central heating system is not going to be used for a long time (for example, during holidays in frost-free periods), it is advisable to put the boiler out of operation.

3.5.1 Boiler with frost protection, out of operation for a long time

- Set the controller low, for example to 10^ ;

The Gas 210 ECO PRO will now only come into operation to protect itself against freezing (= depending on parameter 33). To prevent radiators and the system from freezing in rooms where there is a risk of frost (e.g. garage or storage room), a frost thermostat can be connected to the boiler. The boiler will then keep the radiators in that room warm.

This frost protection does not work if the boiler is out of operation.

3.5.2 Boiler without frost protection, out of operation for a long time

• Isolate the mains power supply from the boiler;
- Close the boiler gas cock.

Tap the boiler and central heating system if you are not going to use your home or the building for a long time and there is a chance of frost.

4. Control stops and faults

4.1 General

The boiler is fitted with an advanced control unit. The heart of the control is a microprocessor, the abc ^® , which both protects and controls the boiler.

Before calling in the installing engineer, first check if:

• the gas cock is open
• the maximum operating temperature setting is high enough
• the boiler control has been correctly set
• the main switch is on
• a sufficient water flow is possible (the radiator valves are entirely opened)
• the water pressure is sufficient (> 0.8 bar).

Note down the failure message before resetting. Reset the failure by pressing the reset-key on the instrument panel.

4.2 Control stops and faults

Control stop:

The control stop is a (temporary) boiler operating mode due to an abnormal situation. The boiler switches to the neutral position so that it can return to a normal state. The display then shows the shutdown status (with code 9) again. The boiler control unit will, at first, try several times to start the boiler again. The boiler shall operate again when the causes of the control stop have been removed.

Fault:

If the shutdown condition still exists even after various automatic control unit start attempts have been made or if a non-reproducible phenomenon has arisen, the boiler switches to fault mode (also known as lock-out). The boiler can only resume operation if the cause of the fault is rectified and the 'RESET button' is pressed

4.3 Control stop codes

The boiler display will show code 9.

The control stop codes can be read out as follows:

• Push the Ⓜ -key, and then the ← -key;
  • The display shows 5t = 9;
• Push the [+] -key one time; the display shows 5 and the control stop code.
  • Note down the control stop code.

The boiler shall start automatically when the causes of the control stop have been removed.

The list enumerates only control stop codes you might be able to solve by yourself. If the control stop code continues to appear after you seem to have rectified the fault, please contact your service engineer. For control stop codes not mentioned in this list also contact your service engineer.

table 02 Control stop codes

4.4 Fault codes

The boiler displays the fault codes as follows:

E 12 (the display shows the ⚠ symbol and the fault code flashes). The meaning of the fault codes can be found in the fault table, see table 03.

In the event of faults, proceed as follows:

• Note the fault code.

The fault code is needed to find the cause of the fault quickly and correctly.

- Press the "RESET -key" for 2 seconds. If the fault code continues to appear, look for the cause in the following fault table and rectify the fault.

If the display does not show RESET but SERVICE, the boiler must be switched off and switched on again after 10 seconds before the fault can be reset.

The list enumerates only fault codes you might be able to solve by yourself. If the fault code continues to appear after you seem to have rectified the fault, please contact your service engineer. For fault codes not mentioned in this list also contact your service engineer.

5.3 Operating principle

The inlet side of the fan is fitted with a venturi, where air and gas are mixed according to a fixed ratio. When there is a heat demand, the fan will pre-vent. The fan draws in the combustion air, which is mixed with the gas to optimum effect in the venturi. The fan moves the homogenous gas/air mixture through to the burner. The mixture is then ignited by the combined ignition and ionisation electrode, which also monitors the flame. Combustion then takes place. Following combustion, the hot flue gases pass through the cast aluminium heat exchanger. Here, the flue gases release their heat to the heating water in the heat exchanger. The heat output of the boiler is controlled on the basis of the settings and the prevailing water temperatures that are measured by the temperature sensors. With flue gas temperatures below dew point (approx. 55°, the temperature at which the water vapour in the flue gases starts to condense), the water vapour in the flue gases will condense in the lower part of the heat exchanger. The heat released during this condensation process (called latent heat or heat of condensation) is also transferred to the heating water. The condensed water is discharged through a trap. The flue gases flow through the condensate collector and are discharged via the flue gas discharge pipe.

The advanced control system of the boiler, the abc ^® , guarantees extremely reliable heat supplies. This means that the boiler responds quickly and efficiently to negative environmental influences (such as hydraulic flow problems, air flow problems, etc.). If problems of this kind occur, the boiler will not lock out, but initially modulate down and, depending on the nature of the problem, switch off temporarily (shutdown or control stop) and try again after a pre-determined time. Providing the situation is not hazardous, the boiler will always continue to attempt to provide heat. For a continuous supply of heat, the boiler requires a minimum flow of 30 % of the nominal water flow at the relevant design temperatures. The boiler can be equipped with a second return (available as an accessory). The second return can contribute additional efficiency if the installation includes different temperature groups.
