Boiler room requirements

!Please note

Incorrect ambient conditions can

lead to damage to the heating

system and put the safe opera-

tion at risk.

■ Ensure ambient temperatures

above 0 ºC and below 35 ºC.

■ Prevent air contamination by

halogenated hydrocarbons

(e.g. as contained in paints,

solvents or cleaning fluids) and

excessive dust (e.g. through

grinding/polishing work).

■ Avoid continuously high humid-

ity levels (e.g. through frequent

drying of washing).

■ Never close existing ventilation

apertures.

Auxiliary components, spare and

wearing parts

!Please note

Components which are not tes-

ted with the heating system may

5592 683 GB

The commissioning and matching of the

control unit to local conditions and build-

ing characteristics, as well as instructing

the user in the operation of the system,

must be carried out by your heating con-

tractor.

As the user of new combustion equip-

ment, you may be obliged to notify your

local flue gas inspector of the installation

[check local regulations]. Your local flue

gas inspector will also inform you [where

appropriate] about work he may be

required to carry out on your combustion

equipment (e.g. regular checks, clean-

ing).

Your system is preset at the factory

The control unit is factory-set to " "

for central heating and DHW heating.

Your heating system is therefore ready

for use:

Central heating

■ The rooms are heated in accordance

with the settings on your control unit

and room temperature control unit.

■ Your heating contractor can make fur-

ther settings for you during commis-

sioning.

You can change any settings individu-

ally at any time to suit your require-

ments (see chapter "Central heating").

DHW heating

■ The DHW is heated to 50 °C.

■ Your heating contractor can make fur-

ther settings for you during commis-

sioning.

You can change any settings individu-

ally at any time to suit your require-

ments (see chapter "DHW heating").

Frost protection

■ Your boiler and DHW cylinder are pro-

tected against frost.

Power failure

■ All data is saved if there is a power

failure.

Introductory information

Commissioning

5592 683 GB

To provide you with a better understand-

ing of the functions of your control unit,

the appendix contains the chapter "Ter-

minology" (see page 29).

Tips on saving energy

Utilise the setting options on the control

unit and the room temperature control

unit:

■ Never overheat your rooms. Every

degree by which the room temperature

is reduced saves up to 6 % on heating

costs.

Never set your room temperature

higher than 20 °C (see page 12).

■ Never set the DHW temperature too

high (see page 14).

■ Select the heating program that meets

your current requirements:

– In the summer, if you do not want to

heat any rooms but require hot

water, select the " " heating pro-

gram (see page 14).

– If you do not want to heat any rooms

and require no hot water for a pro-

longed period of time, select the

" " heating program (see

page 11).

Further recommendations:

■ Correct ventilation/airing.

Briefly open windows fully and at the

same time close the thermostatic radi-

ator valves.

■ Close roller shutters (if installed) at

dusk.

■ Set thermostatic valves correctly.

■ Never cover radiators or thermo-

static valves.

■ Controlled DHW consumption: A

shower generally uses less energy

than a full bath.

You can change the settings for your

heating system centrally at the program-

ming unit of the control unit.

If you have a room temperature control

unit installed in your rooms, you can also

change the settings on the room temper-

ature control unit.

1. Check the heating system pressure

at the pressure gauge. The system

pressure is too low if the indicator

points to the area below 1.0 bar. In

this case, top up with water or notify

your local heating contractor.

2. For open flue operation:

Check that the ventilation apertures

of the installation room are open and

unrestricted.

Note

With open flue operation, the com-

bustion air is drawn from the installa-

tion room.

3. Open the gas shut-off valve.

Note

Ask your heating contractor to

explain the positioning and handling

of these components.

4. Switch ON the power supply, e.g. at

a separate MCB/fuse or a mains iso-

lator.

5. Turn the ON/OFF switch " " ON.

After a short time, the standard dis-

play appears and the green ON indi-

cator illuminates. Your heating sys-

tem and room temperature control

unit are now ready for operation.
