Before a new boiler can be connected to a system, the entire system must

be thoroughly cleaned by flushing it. The flushing will remove residue from

the installation process (weld slag, fixing products etc.) and accumulations

of dirt (silt, mud etc.)

Important

Flush the heating system with a volume of water equivalent to at

least three times the volume of the system.

Flush the domestic hot water pipes with at least 20 times the

volume of the pipes.

4 Preparation of installation

7684359 - v.11 - 13122021 13

Important

Due to the presence of an aluminium heat exchanger, suitable

chemicals and the correct use of these chemicals should be

discussed with specialist water treatment companies.

4.4 Requirements for gas connection

Before starting work on the gas pipes, turn off the main gas tap.

Before installing, check that the gas meter has sufficient capacity. Take

into account the consumption of all appliances.

Notify the local energy company if the gas meter has insufficient

capacity.

Remove dirt and dust from the gas pipe.

Always perform welding work at a sufficient distance from the boiler.

We recommend installing a gas filter to prevent clogging of the gas

valve unit.

4.5.5 Additional guidelines

Installation

For installing the flue gas outlet and air supply materials, refer to the

instructions of the manufacturer of the relevant material. After

installation, check at least all flue gas outlet and air supply parts for

tightness.

Warning

If the flue gas outlet and air supply materials are not installed in

accordance with the instructions (e.g. not leak-proof, not correctly

bracketed), this can result in dangerous situations and/or physical

injury.

Make sure that the flue gas outlet pipe towards the boiler has a sufficient

gradient (at least 50 mm per metre) and that there is a sufficient

condensate collector and discharge (at least 1 m before the outlet of the

boiler). The bends used must be larger than 90° to guarantee the

gradient and a good seal on the lip rings.

Condensation

Direct connection of the flue gas outlet to structural ducts is not

permitted because of condensation.

If condensate from a plastic or stainless steel pipe section can flow back

to an aluminium part in the flue gas outlet, this condensate must be

discharged via a collector before it reaches the aluminium.

Newly installed aluminium flue gas pipes with longer lengths can

produce relatively larger quantities of corrosion products. Check and

clean the siphon more often in this case.

Important

4.6 Requirements for the electrical connections

Establish the electrical connections in accordance with all local and

national current regulations and standards.

Electrical connections must always be made with the power supply

disconnected and only by qualified installers.

The boiler is completely pre-wired. Never change the internal

connections of the control panel.

Always connect the boiler to a well-earthed installation.

The wiring must comply with the instructions in the electrical diagrams.

Follow the recommendations in this manual.

Separate the sensor cables from the 230 V cables

Make sure the following requirements are met when connecting the cables

to the CB and SCB connectors:

Tab.18 PCB connectors

Wire cross section Stripping length Tightening torque

solid wire: 0.14 – 4.0 mm² (AWG 26 – 12)

4 Preparation of installation

20 7684359 - v.11 - 13122021

4.7 Water quality and water treatment

The quality of the heating water must comply with the limit values in our

Water quality instructions. The guidelines in these instructions must be

followed at all times. In many cases, the boiler and central heating system

can be filled with normal tap water and water treatment will not be

necessary.

4.8 Process heat application

In process heat applications (for example pasteurisation and drying and

washing processes), the boiler is being used for industrial purposes and

not for central heating. With process heat, the nominal flow (at ΔT 20°C) in

the primary CH circuit must be guaranteed. The flow in the secondary

circuit may vary.

To ensure that this is the case, a flow rate sensor can be fitted, which

locks out the boiler if the flow falls below a specified level (due to a

defective pump or valve, for example).

Important

The service life of the boiler may be reduced if it is used for

process heat applications.

4.9 Increase default ΔT setting

In some cases, the default ΔT setting of the boiler will need to be

increased, for example in systems with:

underfloor heating

air heating

district heating

a heat pump.

Important

Do not increase the default ΔT setting when the boiler is used in

an open-vented system.

Important

To limit the amount of short cycling, ensure minimum water

circulation by using a bypass or low loss header.

4.10 Open-vented application

In open vented applications the boiler is often operating with lower water

pressure levels. In these cases the default minimum water pressure

setting must be decreased to a value of 0,0 bar.

Partial blocking: boiler frost protection (pump starts when the

temperature of the heat exchanger is < 6°C and the burner starts when

the temperature of the heat exchanger is < 3°C)

Lock out: no frost protection with outdoor sensor and partial boiler frost

protection (pump starts when the temperature of the heat exchanger is <

6°C, the burner does not start when the temperature of the heat

exchanger is < 3°C).

Release input

Caution

Only suitable for potential-free contacts (dry contact).

The boiler has a release input. A potential-free contact can be connected

to the RL terminals of the connector.

If the contact is closed during a heat demand, the boiler will be blocked

immediately.

If the contact is closed when there is no heat demand, the contact does

nothing until the main PCB receives a ‘start burner’- command. After that

command, a waiting time starts. If the contact is closed during this

waiting time, the burner does not start and the boiler will be blocked. Set

the waiting time with parameter AP008. A waiting time of 0 will disable

the contact.

Connecting an outdoor sensor

An outdoor sensor can be connected to the Tout connector. In the case of

an on/off thermostat, the boiler will control the temperature with the set

point from the internal heating curve. An OpenTherm controller can also

use this outdoor sensor. In that case, the desired internal heating curve

must be set on the controller.

Use below mentioned sensors, or sensors with identical characteristics.

Set parameter AP056 to the installed outdoor sensor type.

AF60 = NTC 470 Ω/25°C

QAC34 = NTC 1000 Ω/25°C

1. Connect the plug from the outdoor sensor to the Tout connector.

Frost protection combined with outdoor sensor

The central heating system can also be protected against frost in

combination with an outdoor sensor. The radiator valve in the frost-

sensitive room must be open.

1. Connect the plug from the outdoor sensor to the Tout connector.

The frost protection works as follows with an outdoor sensor:

If the outdoor temperature is lower than the threshold for frost

protection: heat demand from the boiler and the pump starts working.

If the outdoor temperature is higher than the threshold for frost

protection: no heat demand from the boiler.

Important

The outdoor temperature threshold for frost protection can be

changed with parameter AP080.

Connecting the calorifier sensor/thermostat

A calorifier sensor or thermostat can be connected to the Tdhw terminals

of the connector. Only NTC 10 kΩ/25°C sensors can be used.

1. Connect the two-wire cable to the Tdhw terminals of the connector.

5.5.4 Connection options for the expansion PCB - IF-01

The expansion board IF-01 is pre-installed in the instrument box as

standard.

Caution

Do not connect a frost thermostat or room thermostat to the boiler

if using the 0–10 V control PCB.

Connecting the status relay (Nc)

If the boiler locks out, a relay is de-energised and the alarm can be

transmitted via a potential-free contact (maximum 230 V, 1 A) on terminals

Nc and C of the connector.

Connection (OTm)

The interface uses OpenTherm to communicate with the boiler control

unit. To make this possible, the OTm connection must be connected to the

OpenTherm input of the boiler control unit.OTm

8.1 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.

The first letter is the category the code relates to.

AAppliance: Appliance

CCircuit: Zone

DDomestic hot water: Domestic hot water

GGas fired: Gas-fired heat engine

PProducer: Central heating

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.

9 Maintenance

9.1 Maintenance regulations

Important

The boiler must be maintained by a qualified installer in

accordance with local and national regulations.

Important

Adjust the frequency of inspection and service to the conditions of

use. This applies especially if the boiler is:

In constant use (for specific processes).

Used with a low supply temperature.

Used with a high ΔT.

Caution

Replace defective or worn parts with original spare parts. Not

doing so will void warranty.

During inspection and maintenance work, always replace all

gaskets on the parts removed.

Check whether all gaskets have been positioned properly

(absolutely flat in the appropriate groove means they are gas,

air and water tight).

During the inspection and maintenance work, water (drops,

splashes) must never come into contact with the electrical parts.

Warning

Always wear safety goggles and a dust mask during cleaning work

(involving compressed air).

Danger of electric shock

Ensure that the boiler is switched off.

9.2 Maintenance message

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 service 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) put together by Remeha are available from spare parts suppliers.

9 Maintenance

50 7684359 - v.11 - 13122021

Important

Maintenance messages must be followed up within 2 months.

Important

If the iSense or eTwist modulating thermostat is connected to the

boiler, this thermostat can also display the maintenance message.

Consult the thermostat manual.

Caution

Reset the maintenance message following every service.

See

The service manual of the boiler.

See also

Additional documentation, page 8

9.3 Opening the boiler

1. Remove the two screws at the bottom of the front casing.

2. Remove the front panel.

9.4 Standard inspection and maintenance operations

For a service, always perform the following standard inspection and

maintenance operations.

See

The boiler service manual for the specific maintenance work.

9.4.1 Checking the water pressure

1. Check the water pressure.

Important

The recommended water pressure is between 1.5 bar and 2 bar.

The water pressure must be at least 0.8 bar.

2. If necessary, top up the central heating system.

9.4.2 Checking the ionisation current

1. Check the ionisation current at full load and at low load.

The value is stable after 1 minute.

2. Clean or replace the ionisation/ignition electrode if the value is lower

than 4 µA.

9.4.3 Checking the flue gas outlet/air supply connections

1. Check the flue gas outlet and air supply connections for condition and

tightness.

9.4.4 Checking the combustion

Combustion is checked by measuring the O2percentage in the flue gas

outlet duct.

9.4.5 Cleaning the siphon

Danger

The siphon must always be sufficiently filled with water. This

prevents flue gases from entering the room.

1. Dismantle the siphon and clean it.

clean the top part of the heat exchanger (combustion chamber).

9. Vacuum again without the top brush on the end piece.

10. Clean the lower section of the heat exchanger with the special

cleaning blade (accessory).

11. Check (e.g. using a mirror) whether any visible contamination has

been left behind. If it has, remove it with the vacuum cleaner.

12. Check that the burner cover of the dismantled burner is free from

cracks and/or damage. If not, replace the burner.

Servicing the burner is usually not necessary, it is self-cleaning. Use

compressed air to carefully blow away any dust.

13. Reassemble the unit in reverse order.

Caution

Check that the gasket is correctly positioned between the mixing

elbow and the heat exchanger. The gasket must lie absolutely

flat in the appropriate groove to ensure that no gas can leak.

Remember to reconnect the fan plugs.

Tighten the nut on the gas valve unit with a torque of 27.5 N⋅m.

Tighten the front plate nuts with a torque of 10 N⋅m.

14. Open the gas supply and switch the power supply to the boiler back

on.

10 Troubleshooting

10.1 Error codes

The Quinta Ace is fitted with an electronic regulation and control unit. The

heart of the control is a e-Smart microprocessor, which controls and also

protects. In the event of an error, a corresponding code is displayed.

Tab.48 Error codes are displayed at three different levels

Code Type Description

A .00.00 (1) Warning The controls continue to operate, but the cause of the warning must be investigated. A

warning can change into a blocking or lock-out.

H .00.00 (1) Blocking The controls will stop normal operation, and will check with set intervals if the cause of

the blocking still exists.(2) Normal operation will resume when the cause of the blocking

has been rectified. A blocking can become a lock-out.

E .00.00 (1) Lock out The controls will stop normal operation. The cause of the lock-out must be rectified and

the controls must be reset manually.

(1) The first letter indicates the type of error.

(2) For some blocking errors, this checking interval is ten minutes. In those cases, it may seem that the controls do not start automatically.

Wait ten minutes before resetting.

The meaning of the code can be found in the various error code tables.

Important

The error code is needed to find the cause of the error quickly and

correctly and for any support from Remeha.

10.1.1 Display of error codes

11.13 Shut-down

Shut-down the boiler as follows:

1. Turn off the boiler using the on/off switch.

2. Shut off the gas supply.

3. Keep the installation frost-free.

Do not shut-down the boiler if the installation can't be kept frost-free.

11.14 Frost protection

Caution

Drain 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.

The frost protection does not work if the boiler is out of

operation.

The built-in boiler protection is only activated for the boiler and

not for the system and radiators.

Open the valves of all the radiators connected to the system.

Set the temperature control low, for example to 10°C.

If the temperature of the central heating water in the boiler drops too low,

the built-in boiler protection system is activated. This system works as

follows:

If the water temperature is lower than 7°C, the pump switches on.

If the water temperature is lower than 4°C, the boiler switches on.

If the water temperature is higher than 10℃, the burner shuts down and

the pump continues to run for a short time.

To prevent the system and radiators freezing in frost-sensitive areas (e.g.

a garage), a frost thermostat or, if feasible, an outdoor sensor can be

connected to the boiler.

12.5 Boiler pump

A boiler pump is not supplied with this boiler. Take the boiler resistance

and system resistance into account when selecting a pump. The graph

shows the hydraulic resistance at various water flow rates. The table

shows some significant nominal flow data and the corresponding hydraulic

resistance.

If possible, install the pump directly under the boiler on the return

connection.

Important

When the pump is managed by the boiler's control unit, check if

the deaeration program is correctly set (parameter AP101 = 1).
