5.3.7 Frost protection combined with on/off thermostat

Fig.26 to SCB-02

Fig.27 to SCB-02

When an on/off thermostat is used, the pipes and radiators in a frostsensitive 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) and the on/off thermostat (Tk) in parallel to the

R-Bus terminals of the connector.

Warning If a Remeha eTwist or OpenTherm thermostat is used, a frost thermostat cannot be connected in parallel to the R-Bus terminals. In this case, ensure frost protection of the central heating system in combination with an outside sensor.

5.3.8 Frost protection combined with outdoor temperature sensor

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

1. Connect the outdoor temperature sensor to the Tout terminals of the connector.

The frost protection works as follows with an outdoor temperature sensor:

If the outdoor temperature is lower than -10 °C: heat demand from the boiler. If the outdoor temperature is higher than -10 °C: no heat demand from the boiler.

Fig.28 to SCB-02

Fig.29 to CB-09

Important The outdoor temperature before the start of frost protection can be changed with the AP080 parameter.

5.3.9 Connecting an outdoor temperature sensor

An outdoor temperature sensor (accessory) can be connected to the Tout terminals of the connector. If the boiler is equipped with an on/off thermostat, the temperature is controlled using the setpoint of the internal heating curve (F). Various parameter settings can be used to change the internal heating curve.

1. Connect the plug from the outdoor temperature sensor to the Tout terminal.

5.3.10 Blocking input

The boiler has a blocking input (normally closed contact). This input relates to the BL terminals of the connector.

Displaying the water pressure on the control panel

1. Highlight the Water Pressure icon.

The pressure is displayed on the main screen of the control panel.

Modifying the ΔT value

In systems with several operating temperatures, the boiler's ΔT value must be increased.

Tab.19 Standard ΔT values

7717201 - v03 - 25062019 MID _HMI T-control - Gas 120 ACE 39

Gas 120 ACE - 65 25 K 40 K

Gas 120 ACE - 90 25 K 40 K

Gas 120 ACE - 115 20 K 35 K

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.

List of parameters

Fig.58 Code on a OEtroCom-3

Fig.59 First letter

Fig.60 Second letter

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.

The first letter is the category the code relates to.

A Appliance: Appliance C Circuit: Zone D Domestic hot water: Domestic hot water G Gas fired: Gas-fired heat engine P Producer: 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.

The second letter is the type.

P Parameter: Parameters C Counter: Counters M Measurement: Signals

Fig.61 Number

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

7717201 - v03 - 25062019 MID _HMI T-control - Gas 120 ACE 49

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 Maintenance

10.1 General

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.

10.2 Maintenance message

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.

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).

10.3 Standard inspection and maintenance operations

MW-2000560-1

7717201 - v03 - 25062019 MID _HMI T-control - Gas 120 ACE 77

10.3.1 Checking the combustion

Combustion is checked by measuring the O2 percentage in the flue gas discharge pipe.

For more information, see Checking/adjusting the combustion, page 36 Performing the full load test, page 36 Control and setting values for O2 at full load, page 36 Performing the part load test, page 37 Control and setting values for O2 at part load, page 37

10.3.2 Venting the heating system

10 Maintenance

Fig.62

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.

MW-2000561-1

10 Maintenance

78 MID _HMI T-control - Gas 120 ACE 7717201 - v03 - 25062019

10.3.3 Draining the heating system

Fig.63

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.

10.3.4 Check the hydraulic pressure

1. Check the hydraulic pressure in the installation.

Caution The hydraulic pressure must reach a minimum of 0.08 MPa (0.8 bar).

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.

10 Maintenance

7717201 - v03 - 25062019 MID _HMI T-control - Gas 120 ACE 79

7. When the pump has stopped, vent again and top up the water pressure.

Important Filling and venting the installation twice a year should be sufficient to obtain an adequate hydraulic pressure. If it is often necessary to top up the installation with water, contact your installer.

10.3.6 Cleaning the casing

1. Clean the outside of the boiler using a damp cloth and a gentle detergent.

14.1 Energy savings

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.

14.2

Room thermostat and settings

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.
