5.3.5 Connecting a modulating thermostat
The boiler is fitted with an R-Bus connection as standard. This connection is also compatible with OpenTherm. This enables the user to connect
OpenTherm modulating thermostats (such as iSense Pro) or R-Bus thermostats (such as eTwist) without any further adjustments being made to the appliance. The boiler is also suitable for OpenTherm Smart Power.
1. In the case of a room thermostat: install the thermostat in a reference room.
2. Connect the two-wire cable for the thermostat to the R-Bus terminals for the connector. It does not matter which wire is connected to which terminal block.
Important
If the domestic hot water temperature can be set on the
OpenTherm thermostat, the boiler will supply this temperature, with the value set in the boiler as a maximum.
5.3.6 Connecting an on/off thermostat
The boiler is suitable for connection to a two-wire on/off room thermostat
(Tk).
1. Fit the thermostat in a reference room.

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.
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.

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.
7.10 Points to check after commissioning
1. Remove the measuring equipment.
2. Put the flue gas sampling plug back in place.
3. Put the front casing back.

5. Shut down the boiler.
6. After about 10 minutes, vent the air in the heating system.
7. Check that there are no leaks (hydraulic circuit, gas circuit, etc.).
8. Check that the boiler equipment is operating correctly.
9. Check that the thermostats are operating correctly and have the correct settings.

10.1 General
10.2 Maintenance message
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.
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.
Off
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

10.3.2 Venting the heating system
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.

14.1 Energy savings
14.2 Room thermostat and settings
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.
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.
