3.7 Benchmark

Vaillant is a licensed member of the Benchmark Scheme

which aims to improve the standards of installation and com-

missioning of domestic heating and hot water systems in the

UK and to encourage regular servicing to optimise safety, ef-

ficiency and performance.

Benchmark is managed and promoted by the Heating

and Hotwater Industry Council. For more information visit

www.benchmark.org.uk.

▶Please ensure that the installer has fully completed the

Benchmark Checklist on the inside back pages of the

installation instructions supplied with the product and

that you have signed it to say that you have received a

full and clear explanation of its operation. The installer is

legally required to complete a commissioning checklist

as a means of complying with the appropriate Building

Regulations (England and Wales).

All installations must be notified to Local Area Building Con-

trol either directly or through a Competent Persons Scheme.

A Building Regulations Compliance Certificate will then be

issued to the customer who should, on receipt, write the No-

tification Number on the Benchmark Checklist.

This product should be serviced regularly to optimise its

safety, efficiency and performance. The service engineer

should complete the relevant Service Record on the Bench-

mark Checklist after each service.

The Benchmark Checklist will be required in the event of any

warranty.

4.10 Switching off the product's functions

4.10.1 Switching off heating mode (Summer mode)

1. To switch off heating mode without switching off the hot

water generation, press ( ).

◁The value of the heating flow temperature appears

in the display.

2. Use the button to set the heating flow temperature to

Off.

3. Confirm by pressing .

◁Heating mode is switched off.

◁The symbol appears in the display.

4.11 Guaranteeing the correct filling pressure of

the heating installation

4.11.1 Checking the filling pressure of the heating

installation

Note

To ensure that the heating installation operates

smoothly, the filling pressure when the heating

installation is cold must be between 0.10 MPa and

0.20 MPa (1.0 bar and 2.0 bar) or lie between the

two dashed lines in the bar graph display.

If the heating installation extends over several

storeys, a higher filling pressure may be required

for the heating installation. Ask a competent per-

son for details.

In addition, the symbol appears after approx.

one minute.

If the filling pressure in the heating installation

falls below 0.05 MPa (0.5 bar), then the product

switches off. The display alternates between the

fault message F.22 and the current filling pres-

sure.

1. Press twice.

◁The values for the current filling pressure and for the

minimum and maximum filling pressures appear in

the display.

2. Check the filling pressure in the display.

Result 1:

System pressure: 0.10 … 0.20 MPa (1.00 … 2.00 bar)

The filling pressure is in the intended pressure range.

Result 2:

Filling pressure: < 0.08 MPa (< 0.80 bar)

▶Fill the heating installation. (→Page 8)

◁If you have topped up the installation with suf-

ficient heating water, the display automatically

disappears after 20 seconds.

4.11.2 Filling the heating installation

Caution.

Risk of material damage due to heating

water that is extremely calciferous or cor-

rosive or contaminated by chemicals.

Unsuitable tap water damages the seals

and diaphragms, blocks components in the

product and heating installation through

which the water flows and causes noise.

▶Only fill the heating installation with suit-

able heating water.

1. Ask a competent person where the filling cock is loc-

ated.

2. Connect the filling tap to a heating water supply in the

way you were told by the competent person.

3. Open all radiator valves (thermostatic radiator valves) of

the heating installation.

4. Open the heating water supply.

Troubleshooting 5

0020277253_00 ecoFIT sustain Operating instructions 9

5. Turn the filling cock on slowly and allow water to flow in

until the required filling pressure has been reached.

6. Close the heating water supply.

7. Purge all radiators.

8. Check the filling pressure in the display.

9. Top up with more water if necessary.

10. Close the filling cock.

11. Return to the basic display. (→Page 7)

4.12 Protecting the heating installation against

frost

4.12.1 Frost protection function

Caution.

Risk of material damage due to frost.

The frost protection function cannot guaran-

tee flow through the entire heating installa-

tion, which means that parts of the heating

installation may freeze and therefore become

damaged.

▶During a period of frost, ensure that the

heating installation remains in operation

and that all rooms are sufficiently heated,

even when you are away.

Note

To keep the frost protection devices active, you

should switch your product on and off using the

controller, if one is provided.

If the heating flow temperature falls below 5 °C when the

on/off button is on, the product comes into operation and

heats the circulating water to approx. 30 °C on both the heat-

ing side and the hot water side (if available).

4.12.2 Draining the heating installation

When the unit is switched off for an extended period, frost

protection can be guaranteed by completely draining the

heating installation and the product.

▶Consult a competent person about this.

4.13 Switching the product to standby mode

▶Press the reset button for less than three seconds.

◁The display shows OFF and goes out.

◁The product is now in standby mode.

◁The product's frost protection function is activated.

◁The main power supply is not interrupted. The

product continues to be supplied with power.

5 Troubleshooting

5.1 Detecting and rectifying faults

▶If faults occur, proceed in accordance with the table in

the appendix.

Troubleshooting (→Page 11)

▶If the fault cannot be eliminated using the specified

measures or if fault messages (F.xx) occur, contact a

competent person.

5.2 Calling up (Live monitor) status codes

▶Press and at the same time.

Status codes –Overview

◁The current operating mode (status code) is shown

on the display.

6 Care and maintenance

6.1 Maintenance

An annual inspection of the product carried out by a compet-

ent person is a prerequisite for ensuring that the product is

permanently ready and safe for operation, reliable, and has a

long working life.

6.2 Caring for the product

▶Clean the casing with a damp cloth and a little solvent-

free soap.

▶Do not use sprays, scouring agents, detergents, solvents

or cleaning agents that contain chlorine.

6.3 Reading maintenance messages

If the symbol is shown in the display, the product requires

maintenance work.

The product is not in fault mode but continues to operate.

▶Consult a competent person about this.

▶If the water pressure is flashing at the same time, simply

add more heating water.

6.4 Checking the condensate discharge pipe

and tundish

The condensate discharge pipe and tundish must always be

penetrable.

▶Regularly check the condensate discharge pipe and tun-

dish for faults and, particularly, for blockages.

You must not be able to see or feel any obstructions in the

condensate discharge pipe and tundish.

▶If you notice a fault, have it eliminated by a competent

person.

7 Decommissioning

10 Operating instructions ecoFIT sustain 0020277253_00

7 Decommissioning

7.1 Temporarily decommissioning the product

Caution.

Risk of material damage due to frost.

The frost protection and monitoring devices

are only active while the unit is connected

to the power mains and switched on via the

on/off button, and when the gas isolator cock

is open.

▶Temporarily decommission the product

only if no frost is expected.

▶Temporarily decommission the product only if no frost is

expected.

▶Switch off the product via the main switch installed on-

site.

◁The display goes out.

▶When decommissioning the product for a prolonged

period (e.g. holiday), close the gas isolator cock and also,

for combination products, the cold water stop valve.

7.2 Permanently decommissioning the product

▶Have a competent person permanently decommission

the product.

8 Recycling and disposal

▶The competent person who installed your product is re-

sponsible for the disposal of the packaging.

If the product is labelled with this mark:

▶In this case, do not dispose of the product with the

household waste.
