Introduction
Congratulations with the choice you have made, in choosing an ATAG Blauwe Engel S-HR heating boiler. This can be an boiler with or without
hot water facility.
While developing the ATAG Blauwe Engel S-HR it has been taken into account that the boiler adjusts and adapts itself to the required
temperatures. This means that in most practical situations no needless and / or difficult adjustments are necessary in order to supply the
boiler, the heating installation and domestic hot water facility with heat. It’s of course possible to adjust for each installation type different
settings. In most situations the installer will deliver the boiler ready for you to use.
Despite the intelligence and the operational comfort of the boiler, for you as a user, it can be beneficial to know about the operation of the
boiler.
Description of the boiler
The ATAG Blauwe Engel S-HR is a room sealed condensing and modulating central heating boiler which is designed with or without hot
water facility.
A built in ventilating fan sucks in the combustion air from outside and provides for a complete premixing of gas and air.
The gas mixture is lead through a ceramic burner which is above the heat exchanger.
Due to the small flame height a compact construction is possible. After the combustion gasses have passed through the stainless heat
exchanger, they are flued to outside.
Any condensation formed is drained away to waste.
The S-HR-T is an boiler designed with an integrated hot water facility and is provided with a calorifier and a thermostat mixing valve at the
right hand side which supplies a constant water temperature of 60°C.

Operating instructions S-HR series page 2
The unit anticipates the heat required by the heating installation and/or hot water facility.
By doing so as low a possible heat input is given for the required output.
The boiler is provided with an electrical ignition and energy saving pump start to prevent waste of energy. Furthermore the revolutions per
minute of this circulation pump will adjust itself to the amount required by the installation.
As a result unnecessary system noise is prevented.
When the boiler has been out of operation for a longer period of time the circulation pump will periodically start to prevent sticking when an
outside sensor has been connected to the unit. The circulation pump will start automatically when there is a chance of frost to prevent danger
of freezing.
The efficiency of the boiler is very high and the radiation convection and standby losses very low. The emission of noxious substances is
far below the fixed standards so the boiler meets the requirements of SEDBUK Class A.

The boiler
The casing of the boiler consists of metal and synthetic material which can be cleaned with a normal cleanser. At the left front side of the
boiler is an opening door panel. You can already see a part of the control lights and the display through the dark transparant window. After
opening the door, the control panel with the function keys is clearly visible. The control panel is provided with a number of push-buttons with
corresponding lights. The meaning of these push-buttons is explained hereunder.

Operating instructions S-HR series page 2
Program keys with indication lights
Press this key in order to turn on and off the central heating program. This program will become active when the key is pushed and the
indication light is illuminated. In this case the boiler will activate the burner when the room thermostat is calling for heat.
Press this key in order to turn on and off the hot water program. This function only works in the case of an boiler on which a hot water facility
is connected. This programm will become active when the key is pushed and the indication light is illuminated. In this case the boiler
will activate the burner when the calorifier thermostat is calling for heat.
Press this key in order to let the circulation pump circulate according to the automatic switch program or continually via the central heating
installation. The circulation pump will circulate continually via the central heating installation when the key is pushed and the indication
light is illuminated. In most situations the program can stay on automatic, so that the circulation pump starts functioning as desired for central
heating or hot water. If an outside sensor is connected to the unit the pump will start automatically in case of a low outside temperature in
order to reduce the chance of freezing.
At severe frost: It is possible when there is no outstide sensor connected, to choose manually to let the circulation pump
circulate continually to reduce the chance of freezing in the case when there are pipes (garage, attic or other
cold spaces / rooms) which are sensitive to frost.

The boiler display
The reading of the boiler display can be done in two ways.
The reading
During this reading the display will only show what is necessary. Under
normal circumstances the display will give a reading and if a fault
is established this will be reflected with the E for error and a certain
number code.
Choosing a technical or a reading.
In order to switch from a reading to a technical reading for
example the step key should be pushed for 5 seconds.
To return to the reading the step key should be pushed for 5 sec-
onds again.

The technical reading
During this reading the display will show in which operating status the
boiler is active. The technical reading is being repeated every 2
seconds by the reading of the waterpressure .
The first figure of the technical reading indicates the status in
which the boiler is active and the third and fourth figure indicate the water
temperature of the boiler. In case of the reading the character P
stands for pressure which represents the waterpressure. The third and
fourth figure indicate the water-pressure in bar. When a fault occurs it will
be shown by the E of Error with a number code.
The Reset key
The control panel is provided with a reset key. When a fault occurs it will
be shown by the flashing E of Error with a number code after which the
boiler is shut down. After pressing the reset key you can try to start the
boiler again. If the defect keeps returning contact your installer.

Adjusting the flow water temperature
For the user who has chosen the technical reading according to page 5
you can easily adjust the flow water temperature to his or her own wish.
In order to adjust the flow water temperature the following actions have
to be taken.
Push the mode key briefly. The display will show the text which
means that in this chapter adjustments can be made. Then push the step
key. The display will now show The first figure indicates which
adjustment is being shown and the third and the fourth figure shows the
value of this adjustment. The standard adjustment is 85°C flow water
temperature. By means of the + or - key this value can be changed. This
changed value has to be stored by means of the store key. If after this,
the mode key is pushed briefly the technical reading is shown
again.
The flow water temperature that has been adjusted only applies to the
central heating and is independent of the hot water facility for the
calorifier.

Adjusting the type of installation
The boiler is designed in such a way that it will adjust itself automatically to what is necessary for a normal heating system. In some cases
the installation may have convectors or complete underfloor heating. One can easily choose for the type of heating installation adjustments
that belong to the system such as maximum water-flow temperature or for the warming up of the installation after a night period.
In order to be able to adjust this, one needs to push the step key again after the adjustment of the maximum water-flow temperature is
showning the reading . After this the display will show the reading . This means that in this case adjustment 1 is active, and
that, for this installation type 1 has been chosen.
Described below is which installation type can be chosen. By means of the + or the - key the desired installation type can be chosen.
The choice has to be confirmed with the store key after which one can return by means of the mode key to the reading or the technical
reading .

When a type of installation has been
chosen with a low water-flow tempera-
ture it is possible that in case of a severe
winter period the temperature of the
heating system will need to be increased
slightly. In such situations the installation
choice may need to be changed, so that
a higher flow temperature can be
chosen.
More adjustments are defined in the
installation instructions.
