Caution

Make sure the boiler can be reached at all times. The boiler must be installed in a frost-free area. If the power cord is permanently connected, you must always install a main bipolar switch with an opening gap of at least 3 mm (EN 60335-1). Drain the boiler and central heating system if you are not going to use your home 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 boiler protection only protects the boiler, not the system. Check the water pressure in the system regularly. If the water pressure is lower than 0.8 bar, the system must be topped up (recommended water pressure between 1.5 and 2 bar)

Note Keep this document near to the boiler.

Note Casing panels may only be removed for maintenance and servicing purposes. Refit all panels when mainte nance work and servicing are complete.

Note Instruction and warning labels must never be removed or covered and must be clearly legible throughout the entire service life of the boiler. Replace damaged or il legible instruction and warning labels immediately.

Note Modifications to the boiler require the written approval of Remeha.

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 appli ance.

4.2

Operating principle

4.2.1 Circulating pump

The boiler is supplied without a pump. Take the boiler resistance and sys tem 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 11

If possible, install the pump directly under the boiler on the return connec tion.

For more information, see Connecting the heating circuit, page 22

4.2.2 Cascade system

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

Note Contact us for more information.

4.2.3

Water flow

The modulating control of the boiler limits the maximum temperature differ ence 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 m3/h. If progres sive calorifier control is activated with parameter , then maintain a

minimum water flow of 0.8 m

/h.

4.2.4

Calorifier connection

A calorifier can be connected to the boiler. Our range includes various cal orifiers.

Note Contact us for more information.

Connect the calorifier to the boiler with a calorifier pump. A three-way valve is not suitable due to the hydraulic resistance. An optional PCB is re quired to connect a calorifier pump.

Fig.7 Mounting the boiler

AD-0000018-01

6 Installation

123157 - v.07 - 10082015 21

Page 22

step is absolutely crucial. The flushing helps to remove residue from the installation process (weld slag, fixing products etc.) and accumulations of dirt (silt, mud etc.)

Note Flush the CH installation with a volume of water equivalent to at least three times the volume of the CH installation. Flush the DHW pipes with at least 20 times the volume of the pipes.

Note Due to the presence of an aluminium heat exchanger, suitable chemicals and the correct use of these chemicals should be dis cussed with specialist water treatment companies.

6.3.2 Connecting the heating circuit

1. Remove the dust cap from the CH flow connection at the bot tom of the boiler.

2. Fit the outlet pipe for CH water to the CH flow connection.

3. For filling and tapping the boiler, install a filling and drain valve in the system.

4. Remove the dust cap from the CH return connection at the bot tom of the boiler.

5. Fit the inlet pipe for CH water to the CH return connection.

6. Install the pump in the CH return pipe (if applicable).

See For the pump's electrical connection: Connecting the pump, page 31

Note Fit a service shut-off valve in the CH flow pipe and the CH return pipe to facilitate servicing work.

Caution

When fitting service shut-off valves, position the filling and drain valve, the expansion vessel and the safety valve between the shut-off valve and the boiler. Carry out any welding work required at a safe distance from the boiler or before the boiler is fitted. If using synthetic pipes, follow the manufacturer's (connection) instructions. When installing open-vented systems, the cold feed and expan sion tank heights must comply with the requirements laid down in the Health and Safety Executive publication PM5.

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 dis charged 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 to gether with the condensate must be taken into account the first time. Clean the siphon of the appliance regularly or install an extra conden sate 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 conden sate 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.

Note Contact us for more information.

Frost protection combined with on/off thermostat

When an on/off thermostat is used, the pipes and radiators in a frost-sen sitive 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 ga rage).

2. Connect the frost thermostat (Tv) parallel to the on/off thermostat (Tk) on the On/Off OT terminals of the connector.

Note When an OpenTherm thermostat is used, it is not possible to con nect 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 combina tion 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°C (can be set with parameter

): the circulating pump switches on.

At an outside temperature higher than -10°C (can be set with parameter

): the circulating pump continues to run and then switches off.

Connecting an outside sensor

Ba Outside sensor An outside sensor can be connected to the Tout terminals of the connector (accessory). In the event of an on/off thermostat, the boiler will regulate the temperature using the set point of the internal heating curve (F). Vari ous parameter settings can be used to change the internal heating curve.

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

Note An OpenTherm controller can also use this outside sensor. In that case, the required internal heating curve must be set on the con troller.

6.7 Filling the system

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, pHincreasing or lowering agents, chemical additives and/or inhibitors. Such agents can cause errors in the boiler and damage to the heat exchanger.

Note

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 °dH (dependent on the total heat output generated). More information is available in our Water quality regulations. Always adhere to the instructions in the aforementioned docu ment.

6.7.2

Filling the siphon

Danger The siphon must always be sufficiently filled with water. This pre vents flue gases from entering the room.

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.

Note 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.

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

2. Check the water-side connections for tightness.

Fig.35 Filling the siphon

6 Installation

40 123157 - v.07 - 10082015

Page 41

Note After switching on the power and if there is adequate water pres sure, 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 pro gram starting up. That would indeed be undesirable if the boiler is not filled. Switch the boiler off if the CH installation is not be ing 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

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. The frost protection does not work if the boiler is out of opera tion. 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 fol lows:

At a water temperature lower than 7°C, the heating pump starts. If the water temperature is lower than 4°C, 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. Depend ing 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 in staller. During inspection or maintenance work, always replace all gas kets of the disassembled parts. Replace defective or worn parts with original spare parts. An annual inspection is mandatory.

10.2

Service message

The boiler display will clearly indicate that a service is required at the ap propriate time. Use the automatic service message for preventive mainte nance 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.

Note

A service message must be followed up within 2 months. There fore, call your installer as soon as possible. If the iSense modulating thermostat is connected to the boiler, this service message can also be forwarded to the iSense. Con sult the thermostat manual.

Caution Reset the service message following every service.

10.2.1 Resetting the service messages

A service message on the boiler display must be reset by a qualified in staller after the maintenance service has been carried out using the rele vant service kit. Proceed as follows:

1. When the maintenance message is displayed, press the key once.

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 main tenance operations.

Caution

Check whether all gaskets have been positioned properly (abso lutely 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 electri cal 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.

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

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 pro tects 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.

Note 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 ). The con trol unit makes a number of attempts to start the boiler again. The blocking codes can be read out as follows:

1. Press the two keys at the same time.

2. Confirm by pressing key . The display alternates between and the blocking code .

3. Press the key.

14.3.2 Connection options for the PCB (SCU-S03)

If the boiler is fitted with the PCB (SCU-S03), then this PCB is automatical ly recognised by the boiler's automatic control unit.

Note On removing this PCB, the boiler will show error code . To prevent this error, an auto-detect must be carried out after remov ing this PCB. For information on carrying out an auto-detect, see: Carrying out an auto-detect, page 53

Connecting the minimum gas pressure switch (Gps)

The minimum gas pressure switch blocks the boiler if the gas inlet pres sure becomes too low.

1. Connect the minimum gas pressure switch to the Gps terminals of the connector.

The presence of the gas pressure switch must be set using parameter

Connecting a heat recovery unit (Hru)

1. Connect the wires from the heat recovery unit to the Hru terminals of the connector.

14.3.4 Connection options for the PCB (SCU-X03)

The SCU-X03 PCB can control a modulating central heating pump. De pending on the make and type of pump, the pump can be controlled by a 0–10 V, 4–20 mA or a PWM signal. The speed of the pump is modulated based on the signal received from the boiler.

Note For correct connection of the pump, see the documentation sup plied with the pump.

Connecting on/off contact

1. Connect the on/off contact of the CH pump to the connector X1.

Caution Do not use the on/off contact to interrupt the power supply to the pump.

Connecting a central heating pump

1. Connect the CH pump controller to the connector X2.

Select the type of signal that will be received from the boiler using the rota ry knob SW1 on the PCB. See table below

Caution

If possible, use the pump modulation signal. This provides the most accurate pump control. In positions 3 to 9 the control PCB receives no signal from the boiler and the boiler responds as in position 0. If the automatic burner unit does not support pump modulation, the pump will behave as an on/off pump.

Select the type of signal that controls the pump using the rotary knob SW2 on the PCB. See table below.
