7.6 Starting and stopping the boiler

7.6.1 Commissioning

Caution

Initial commissioning must be done by a qualified professional.

If adapting to another type of gas, e.g. propane, the boiler must be adjusted before it is switched on.

1. Open the main gas valve.

2. Switch the power on with the boiler's on/off switch.

The boiler starts before the control panel display is active.

3. Set the following parameters when the appliance is first switched on:

Select Country and Language

Configure the date and time used by the appliance

Enable Daylight Saving Time

CN1 and CN2 (codes present on the boiler data plate).

4. Set the components (thermostats, control system) so that they request heat.

5. Check the hydraulic pressure in the installation shown on the control panel display.

Recommended hydraulic pressure between 0.15 and 0.2 MPa (1.5 and 2.0 bar).

Important

In the event of an error during start-up, a message with the corresponding code is displayed. The meaning of the error codes can be found in the error table.

7.6.2 Shutting down the boiler

The boiler must be shut down in order for certain operations to be carried out on the equipment or its environment.

In other situations, such as an extended absence period we recommend that Holiday Mode mode is used in order to benefit from the heating pump anti-blocking function and to protect the installation from frost.

To shut down the boiler:

1. Press the on/off switch.

Increase the ΔT value using the GP021 parameter. When increasing the

ΔT, the control unit limits the linear flow temperature to 80 °C maximum.

This does not modify the value set for the maximum flow temperature. This value can be adjusted using the CP000 parameter.

Important

If the heat demand is greater than 80 °C with the increased ΔT value, Recom (or the service tool) will use a sub-status to indicate that the limited flow temperature is active.

Always ensure that circulation is minimal (using a bypass or low-loss header if necessary) to prevent the boiler from locking out.

If a PWM-controlled central heating pump is controlled by the boiler control panel, set the PP014 parameter to 2.

7.10 Points to check after commissioning

1. Remove the measuring equipment.

2. Put the flue gas sampling plug back in place.

3. Put the front casing back.

4. Bring the heating system temperature up to approximately 50°C.

5. Shut down the boiler.

6. After about 10 minutes, vent the air in the heating system.

7. Check that there are no leaks (hydraulic circuit, gas circuit, etc.).

8. Check that the boiler equipment is operating correctly.

9. Check that the thermostats are operating correctly and have the correct settings.

10. Check the water pressure. Recommended pressure: between 0.15 and 0.2 MPa (1.5 and 2.0 bar).

11. Tidy away or scrap the various packaging items.

12. If necessary, affix the second type plate provided with the documentation to a visible part of the boiler.

13. Affix the data plate supplied with the control box beside the boiler type plate.

14. Instruct the user in the operation of the system, boiler and controller.

15. Inform the user of the periodicity of maintenance work to be carried out.

16. Hand over all manuals to the user.

Commissioning of the boiler is now complete.

9.10.1 Introduction to parameter codes

The controls platform makes use of an advanced system to categorise parameters, measurements and counters. Knowing the logic behind these codes, makes it easier to identify them. The code consists of two letters and three numbers.

CP010

AD-3001373-02

C P010

AD-3001375-01

C P 010

AD-3001376-01

CP 010

AD-3001377-01

The first letter is the category the code relates to.

A

C

D

G

P

Appliance: Appliance

Circuit: Zone

Domestic hot water: Domestic hot water

Gas fired: Gas-fired heat engine

Producer: Central heating

P

C

M

Category D codes are appliance controlled only. When the domestic hot water is controlled by an SCB, it is handled like a circuit, with C-category codes.

The second letter is the type.

Parameter: Parameters

Counter: Counters

Measurement: Signals

The number is always three digits. In certain cases, the last of the three digits relates to a zone.

9.10.2 Changing the parameters

The boiler’s control unit is set for the most common central heating systems. These settings will ensure that virtually every central heating system operates effectively. The user or the installer can optimise the parameters as required.

Caution

Changing the factory settings may adversely affect the operation of the boiler.

9.10.3 Control unit settings

Important

All tables show the factory setting for the parameters.

The tables also list parameters that are only applicable if the boiler is combined with other equipment such as an outdoor sensor.

All possible options are indicated in the adjustment range. The display of the boiler only shows the relevant settings for the appliance.

10.1 General

10.2 Maintenance message

We recommend having the boiler inspected and serviced at regular intervals.

Caution

Do not neglect to service the boiler. Contact a qualified professional or take out a maintenance contract for the obligatory annual servicing of the boiler.

Failure to service the appliance voids the warranty.

Danger of electric shock

Before service work is started, the boiler has to be de-energised and secured from accidentally being switched back on.

Caution

Have an inspection carried out and the flues swept at least once a year or more, depending on the regulations in force in your country.

Caution

Only qualified professionals are authorised to carry out maintenance work on the boiler and the heating system.

Caution

After maintenance or repair work, check the entire heating system to ensure that there are no leaks.

Caution

Only genuine spare parts may be used.

Off

The boiler display will clearly indicate that a service is required at the appropriate time. Use the automatic maintenance message for preventive maintenance, to keep faults to a minimum. The maintenance messages show which service kit must be used. These service kits contain all parts and gaskets that are required for the relevant service. These service kits

(A, B or C) are available from your spare parts supplier.

Important

A maintenance message must be followed up within 2 months.

Call your installer as soon as possible.

Caution

Reset the maintenance message following every service.

10.2.1 Viewing the service notifications

When a service notification appears on the display, you can view the details of the notification.

1. Select the Maintenance icon.

Information about maintenance is displayed (cannot be modified).

Control and setting values for O2 at part load, page 37

10.3.2 Venting the heating system

Any air in the boiler, pipes or valves must be vented in order to prevent annoying noises that may be generated during heating or when drawing water.

1. Open the valves of all the radiators and/or underfloor heating circuits connected to the system.

2. Set the room thermostat to the highest possible temperature.

3. Wait until the radiators are warm.

4. Shut down the boiler.

5. Wait approximately 10 minutes, until the radiators feel cold.

6. Bleed the radiators. Work from the lowest to the highest.

7. Open the venting valve with the bleed key, keeping a cloth pressed against the vent.

Warning

The water may still be hot.

8. Wait until water comes out of the venting valve and then close the venting valve.

9. Start the boiler.

Important

After the power is switched on, the boiler always runs through an automatic venting program lasting approx. 3 minutes.

10. After venting, check that the water pressure in the system is still adequate. If necessary, top up the water level in the heating system

11. Adjust the room thermostat or temperature control.

10.3.3 Draining the heating system

It may be necessary to drain the central heating system if radiators need to be replaced, if there is a major water leak or if there is a risk of freezing.

1. Open the valves on all the radiators connected to the system.

2. Shut down the boiler.

3. Wait approximately 10 minutes, until the radiators feel cold.

4. Connect a drain hose to the lowest draining point. Place the end of the hose in a drain or at a place where drained pipe water will not cause any damage.

5. Open the central heating system filling/draining valve. Drain the installation.

Warning

The water may still be hot.

6. Close the drain valve when no more water comes from the draining point.

Important

If the hydraulic pressure is lower than 0.08 MPa (0.8 bar), the bar symbol flashes.

2. Top up the heating system with water to increase the hydraulic pressure.

Important

The recommended hydraulic pressure when cold is between 0.15

MPa (1.5 bar) and 0.2 MPa (2 bar).

For more information, see

Displaying the water pressure on the control panel, page 38

10.3.5 Topping up the installation with water

1. Open the valves on all radiators connected to the heating system.

2. Set the room thermostat to as low a temperature as possible.

3. Put the boiler in shut-down/frost protection mode.

4. Open the fill valve.

5. Close the filling valve when the pressure gauge shows a pressure of

0.15 MPa (1.5 bar).

6. Put the boiler in heating mode.

14.1 Energy savings

14.2 Room thermostat and settings

Energy-saving advice:

Do not block ventilation outlets.

Do not cover the radiators. Do not hang curtains in front of the radiators.

Install reflective panels behind the radiators to prevent heat losses.

Insulate the pipes in rooms that are not heated (cellars and lofts).

Close the radiators in rooms not in use.

Do not run hot (or cold) water pointlessly.

Install an energy-saving shower head, which can save up to 40 % energy.

Take showers rather than baths. A bath consumes twice as much water and energy.

Various models of room thermostat are available. The type of thermostat used and the parameter selected impact total energy consumption.

A modulating regulator, which may be combined with thermostatic valves, is eco-friendly in terms of energy and offers an excellent level of comfort. This combination allows you to set the temperature separately for each room. However, do not install thermostatic radiator valves in the room in which the room thermostat is located.

Complete opening and closing of the thermostatic radiator valves causes undesirable variations in temperature. Therefore, these must be opened/closed progressively.

Set the room thermostat to a temperature of approximately 20°C to reduce heating costs and energy consumption.

Lower the thermostat setting to approximately 16°C at night or when you are not at home. This reduces heating costs and energy consumption.

Lower the thermostat setting well before airing the rooms.

Set the water temperature to a lower level in summer than in winter (e.g.

60°C and 80°C respectively) when an ON/OFF thermostat is used.

When clock thermostats and programmable thermostats are to be set, do not forget to take any holidays and days when no one is at home into account.
