4 Description of the product

4.1 General description

POWER HT + floor-standing condensing gas boilers have the following characteristics:

Low pollutant emissions High efficiency heating Electronic control panel Flue gas discharge by a forced flue, chimney or bi-flow type connection. Perfectly suitable for cascade systems with several boilers.

4.2

Operating principle

4.2.1

Circulation pump

Note The benchmark for the most efficient circulators is EEI ≤ 0.20.

4.2.2 Gas/air setting

The casing fitted to the boiler is also used as an air box. Air is drawn in by the fan and gas injected into the Venturi by the fan intake. The fan speed is modulated according to the settings, the heat demand and the actual temperatures measured by the temperature sensors. The gas and air are mixed in the Venturi. The gas/air ratio command function accurately ad justs the quantities of gas and air required. This provides optimum com bustion over the entire output range. The gas/air mixture is sent to the burner, located upstream of the heat exchanger.

4.2.3 Low-loss header (accessory)

The low-loss header is used to prevent interaction between the dynamic pressures within the boiler and the heating circuits. The low-loss header considerably reduces the variations in pressure and flow rate caused by the use of several circulating pumps in an installation and is used to man age flows in the installation and to control temperatures.

header kit

4.2.4 System in cascade

The boiler is ideally suited for a cascade system configuration. Use a boil er/cascade connection kit to connect boilers in cascade.

Note Please contact the After Sales Service for further information.

4.2.5 Settings and safety devices

Note The settings and safety devices are only operational if the boiler is powered up.

Tab.10 Description of the safety devices

Device Description

Safety thermostats The safety thermostats suspend the supply of gas to the burner if the water in the pri

mary circuit overheats. To resume normal operation of the boiler, eliminate the cause of this interruption.

Caution The safety thermostats must in no circumstances be switched off or disconnected.

NTC flue gas sensor The control panel blocks the gas supply to the burner in the event of overheating. To

resume normal operation of the boiler, switch off the boiler and switch it back on again with the ON/OFF switch.

Flame detector by ionisation The boiler is put into safety shut-down in the event of gas shortage or incomplete inter

ignition on the burner.

Hydraulic pressure switch Thanks to this device, the burner can only operate if the system pressure is higher than

0.5 bar (0.05 MPa). When the pressure switch detects a pressure lower than 0.8 bar (0.08 MPa), a warning message is displayed, without stopping the circulating pump.

Post-circulating pump After the burner stops, depending on the room thermostat setting and if in heating

mode, the circulating pump runs for a further 3 minutes.

Frost protection device When the flow temperature is lower than 5°C, the burner starts up and runs until the

flow temperature reaches 15°C. This device runs under the following conditions:

The boiler is switched on The gas supply is working The pressure in the system is higher than 0.5 bar (0,05 MPa)

Anti-blocking of the pump If there are no heating or domestic hot water requirements for 24 consecutive hours, the

pumps start up automatically and run for 10 seconds. The pumps connected directly to the appliance's terminal blocks are started up every Friday at 10:00 a.m. and run for 30 seconds.

Anticipatory start-up of the circulat ing pumps

In heating mode only, the appliance can start up the circulating pumps before burner ig nition. The duration and activation of anticipatory start-up depends on the conditions of installation and the operating temperatures. The duration of anticipatory start-up of the circulating pumps therefore varies from a few seconds to several minutes.

7.1 General

We recommend having the boiler inspected and serviced at regular inter vals.

Boiler maintenance and cleaning must be carried out at least once a year by a qualified professional. 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 Failure to service the appliance voids the warranty.

Caution Maintenance work must be carried out by a qualified professional.

Caution Only genuine spare parts may be used.

133 133:Safety time exceeded Ignition error (4 attempts).

Note Contact the installer:

If an error code different from the ones described is displayed on the screen If an error code is displayed on a regular basis

Note If the error code simultaneously displays the and symbols, contact the accredited technical assistance service.

Code E110 The code E110 is displayed when overheating occurs due to a breach in the insulation:

Remove the heat exchanger. Replace the insulation behind the burner bracket. Replace the safety thermofuse behind the heat exchanger.

8.1.1 Automatic error code clearing

If the symbol is displayed at the same time as the error code, the error code is automatically cleared when the cause that prompted it stops.

A flow or return temperature in excess of the critical value prompts an er ror code. The error code is automatically cleared when the temperature drops below the critical value.

8.1.2 Clearing error codes

If the probable cause of an error code is resolved but the error code con tinues to be displayed, proceed as follows to clear the error code:

1. Press the button. The command Reset? Yes is displayed on the control panel.

2. Confirm by pressing the button. The error code disappears after a few seconds.

9.1 Energy savings

Tips on saving energy:

Keep the room in which the boiler is installed well ventilated. 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). Turn off the radiators in rooms not being used. Do not run hot (or cold) water pointlessly. Install a water-saving shower head to save up to 40% energy. Take showers rather than baths. A bath consumes twice as much water and energy.

9.2

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 cau ses undesirable variations in temperature. Therefore, these must be opened/closed progressively. Set the room thermostat to a temperature of approximately 20°C to re duce 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.
