4 Description of the product

4.1 General description

The Quinta Pro boiler has the following characteristics:

• High-efficiency heating.
- Limited emissions of polluted substances.
- Ideal choice for cascade configurations.
- Option to produce domestic hot water using a separate hot water appliance.

4.2 Operating principle

4.2.1 Circulating pump

■ Model not supplied with circulating pump

The boiler is supplied without a pump. Take the boiler resistance and system resistance into account when selecting a pump.

Caution

The pump may have a maximum input of 200 W. Use an auxiliary relay for a pump with greater power.

See

Technical data, page 12

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

For more information, see

Connecting the heating circuit, page 23

■ Pump settings

The pump settings for a modulating circulating pump controlled by the control unit can be modified using parameters P480: P29

• If there is insufficient flow in the radiators or if they do not warm up completely, the minimum pump speed can be increased using parameter P 28.
• If there are audible flowing noises in the system, the maximum pump speed must be lowered using parameter P2 Qbleed the CH installation first).

Caution

The pump may have a maximum input of 200 W. Use an auxiliary relay for a pump with greater power.

For more information, see

Changing the parameters at installer level, page 54

4.2.2 Cascade system

The boiler is ideally suited for a cascade system. There are a number of standard solutions available.

Important

Contact us for more information.

4.2.3 Water flow

The modulating control of the boiler limits the maximum temperature difference between the flow and return and the maximum rise velocity of the

flow temperature. As a result, the boiler is virtually unaffected by low water flow. In all cases, maintain a minimum water flow of 0.4 m^3/h . If progressive calorifier control is activated with parameter P then maintain a minimum water flow of 0.8 m^3/h .

4.2.4 Calorifier connection

A calorifier can be connected to the boiler. Our range includes various calorifiers.

Important

6.5.5 Additional guidelines

• For installing the flue gas outlet and air supply materials, refer to the instructions of the manufacturer of the relevant material. If the flue gas outlet and air supply materials are not installed in accordance with the instructions (e.g. not leakproof, not properly bracketed), this can result in dangerous situations and/or physical injury. After installation, check at least all flue gas outlet and air supply parts for tightness.
• Direct connection of the flue gas outlet to structural ducts is not permitted because of condensation.
• Always clean shafts thoroughly when using lining pipes and/or an air supply connection.
• It must be possible to inspect the lining duct.
• 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.
• With longer lengths of aluminium flue gas outlet pipes, relatively large quantities of corrosion products flowing back out of the outlet pipes together with the condensate must be taken into account the first time. Clean the siphon of the appliance regularly or install an extra condensate collector above the unit.
• 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.

■ Frost protection combined with on/off thermostat

When an on/off thermostat is used, the pipes and radiators in a frost-sensitive room can be protected by a frost thermostat. The radiator valve in the frost-sensitive room must be open.

1. Place a frost thermostat (Tv) in a frost-sensitive room (e.g. a garage).
2. Connect the frost thermostat (Tv) parallel to the on/off thermostat (Tk) on the On/Off OT terminals of the connector.

Important

When an OpenTherm thermostat is used, it is not possible to connect a frost thermostat parallel to the On/Off OT terminals. In that case, implement frost protection of the central heating system in combination with an outside sensor.

■ Frost protection combined with outside sensor

The central heating system can also be protected against frost in combination with an outside sensor. The radiator valve in the frost-sensitive room must be open.

1. Connect the outside sensor to the Tout terminals of the connector.

The frost protection works as follows with an outside sensor:

• At an outside temperature lower than -10^ (can be set with parameter P30): the circulating pump switches on.
• At an outside temperature higher than -10^ (can be set with parameter P30): the circulating pump continues to run and then switches off.

■ Connecting an outside sensor

6.7 Filling the installation

6.7.1 Water treatment

In many cases, the boiler and central heating system can be filled with normal tap water and water treatment will not be necessary.

Warning

Do not add chemical agents to the central heating water without consulting Remeha. For example: antifreeze, water softeners, pH-increasing or lowering agents, chemical additives and/or inhibitors. Such agents can cause errors in the boiler and damage to the heat exchanger.

Important

• For untreated water, the pH value of the water in the installation must be between 7 and 9 and for treated water between 7 and 8.5.
• The maximum hardness of the water in the installation must be between 0.5 and 20.0^ (dependent on the total heat output generated).
• More information is available in our Water quality regulations. Always adhere to the instructions in the aforementioned document.

6.7.2 Filling the siphon

Danger

The siphon must always be sufficiently filled with water. This prevents flue gases from entering the room.

Fig.35 Filling the siphon

Illustration of a faucet dispensing liquid into a test tube (no text or symbols)

AD-0000064-01

1. Remove the siphon.
2. Fill the siphon up with water.
3. Fit the siphon.
4. Check whether the siphon is firmly fitted in the boiler.

6.7.3 Filling the system

Caution

Before filling, open the valves on every radiator in the installation.

Important

In order to be able to read off the water pressure from the boiler display, the boiler must be switched on.

1. Fill the central heating system with clean tap water.

Important

The recommended water pressure is between 1.5 and 2 bar.

1. Check the water-side connections for tightness.

Important

After switching on the power and if there is adequate water pressure, the boiler always runs through an automatic venting program lasting approximately 3 minutes (air may escape via the automatic air vent during filling). If the water pressure is lower than 0.8 bar, the symbol will appear. If the water pressure is too low, top up the CH installation.

Caution

• Carry out the filling within 30 minutes to avoid the venting program starting up. That would indeed be undesirable if the boiler is not filled. Switch the boiler off if the CH installation is not being topped up immediately.
• When venting, prevent water from getting into the boiler casing and electrical parts of the boiler.

8.2 Shutdown

If the central heating is not due to be used for a long period of time, it is recommended that the boiler be disconnected from the power supply.

1. Switch off the boiler's electrical connection.
2. Shut off the gas supply.
3. Keep the area frost-free.

8.3 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 there is no heat demand, the boiler will only switch on to protect itself against frost.

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:

- At a water temperature lower than 7^ , the heating pump starts.

- If the water temperature is lower than 4^ , the boiler switches on.

- If the water temperature is higher than 10^ the boiler switches off and the circulation 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 outside sensor can be connected to the boiler.

10 Maintenance

10.1 General

The boiler does not require a lot of maintenance. Nevertheless, the boiler must be inspected and maintained periodically. To determine the best time for servicing, the boiler is equipped with an automatic service message. The control unit determines when this service message appears. Depending on boiler use, the first service message appears no later than 3 years after installation of the boiler.

Caution

• Maintenance operations must be completed by a qualified installer.
• During inspection or maintenance work, always replace all gaskets of the disassembled parts.
• Replace defective or worn parts with original spare parts.
  • An annual inspection is mandatory.

10.2 Maintenance message

The boiler display will clearly indicate that a service is required at the appropriate time. Use the automatic service 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 your spare parts supplier.

Important

A service message must be followed up within 2 months. Therefore, call your installer as soon as possible.

Important

If the iSense modulating thermostat is connected to the boiler, the thermostat can also display the maintenance message. Consult the thermostat manual.

Caution

Reset the maintenance message following every service.

10.2.1 Resetting the service messages

A service message on the boiler display must be reset by a qualified installer after the maintenance service has been carried out using the relevant service kit. Proceed as follows:

Warning

Always wear safety goggles and a dust mask during cleaning work (involving compressed air).

For a service, always perform the following standard inspection and maintenance operations.

Caution

- Check whether all gaskets have been positioned properly (absolutely flat in the appropriate groove means they are gas tight).

- During the inspection and maintenance operations, water (drops, splashes) must never come into contact with the electrical parts.

10.3.1 Checking the water pressure

1. Check the water pressure.

→ The water pressure must be at least 0.8 bar. If the water pressure is too low, the symbol will appear.

Important

For open vented systems, the water pressure must be at least 0.3 bar (Q30/Q45/Q65/Q90) or 0.5 bar (Q115).

1. If necessary: top up the central heating system.

11 Troubleshooting

11.1 Error codes

The boiler is fitted with an electronic regulation and control unit. The heart of the control is a microprocessor, the Comfort Master ^® , which both protects and controls the boiler. In the event of an error, a corresponding code is displayed.

The meaning of the error codes can be found in the error table.

Important Note the error code displayed. The error code is needed to find the cause of the error quickly and correctly and for any support from Remeha.

11.1.1 Blocking

A (temporary) blocking mode is a boiler status, resulting from an abnormal state. The display shows a blocking code (for example \$5The control unit makes a number of attempts to start the boiler again. The blocking codes can be read out as follows:

Fig.65 Blocking code

11.1.2 Lock out

If the blocking conditions still exist after various start attempts, the boiler goes into lockout (also called error). The boiler will also lock out if an error is signalled anywhere in the boiler. An error code will appear on the display. The error code is displayed as follows:

In a red flashing display:

• the symbol
• the symbol RESET
• the error code, for example E:01

The meaning of the error codes can be found in the error table. Note the error code.

Important

The error code is needed to find the cause of the error quickly and correctly and for any support from Remeha.

Press the RESET for two seconds. If the error code continues to display, search for the cause in the error table and apply the solution.

Important

If the display does not show RESET rather, the boiler must be switched off and then switched on again 10 seconds later before the error can be reset.
