Introduction
Congratulations with the choice you have made, in choosing a STREBEL S-HR heating apparatus. This can be an apparatus with or without
hot water facility.
While developing the STREBEL S-HR it has been ta en into account that the apparatus adjusts and adapts itself to the required
temperatures. This means that in most practical situations no needless and / or difficult adjustment are necesessary in order to supply the
apparatus, the heating installation and .. hot water facility with heat. Its of course possible to adjust for each installation type different settings.
In most situations the installator will deliver the apparatus ready for you to use.
Despite the intelligence and the operational comfort of the apparatus, for you as a user, it can be beneficial to now about the operation of
the apparatus.
Description of the apparatus
The STREBEL S-HR is a room sealed condensing and modulating central heating apparatus which is designed with or without hot water
facility.
A built in ventilating fan suc s in the combustion air from outside and provides for a complete premixing of gas and air.
The gas mixture is leaded through a ceramic burner which is placed 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 apparatus designed with an integrated hot water facility and is provided with a calorifier and a thermostat mixing valve
at the rightside which supplies a constant water temperature of 60°C.

Operating instructions S-HR serial page 2
The unit anticipates the heat required by the heating installation and/or hot water facility.
By doing so a low as possible heat input is given for the required output.
The apparatus 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 apparatus has been out of operation for a longer period of time the circulation pump will periodically start to prevent stic ing 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 apparatus 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 apparatus meets the requirements of the Gas eur HR (High Efficiency) and Gas eur SV (Clean
Combustion).
If the apparatus is designed in combination with the Brain thermostat, information about the wor ing of the apparatus can be displayed at
the Brain thermostat. It is also possible to turn on and select from this thermostat the different programs. For more information on the Brain
thermostat you are referred to the user instructions of the Brain thermostat.

The apparatus
The casing of the apparatus consists of metal and synthetic material which can be cleaned with a normal cleanser. At the left front side off
the apparatus is a revolving door. You can already see a part of the control lights and the display through the dar transparant window. After
opening the door, the control panel with the function eys 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.

Program keys with indication lights
Press this ey in order to turn on and off the central heating program. This program will become active when the ey is pushed and the
indication light is illuminated. In this case the apparatus will activate the burner when the room thermostat is calling for heat.
Press this ey in order to turn on and off the hot water program. This function only wor s in the case of an apparatus on which a hot water
facility is connected. This programm will become active when the ey is pushed and the indication light is illuminated. In this case the
apparatus will activate the burner when the calorifier thermostat is calling for heat.
Press this ey 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 ey 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 apparatus display
The reading of the apparatus 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 ey should be pushed for 5 seconds.
To return to the reading the step ey should be pushed for 5 sec-
onds again.

The technical reading
During this reading the display will show in which operating status the
apparatus 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 apparatus is active and the third and fourth figure indicate the
water temperature of the apparatus. 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 certain numbercode.
The Reset key
The control panel is provided with a reset ey. When a fault occurs it will
be shown by the flashing E of Error with a certain numbercode after which
the apparatus is shut down. After pressing the reset ey you can try to
start the apparatus again. If the defect eeps 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 ta en.
Push the mode ey briefly. The display will show the text which
means that in this chapter adjustments can be made. Then push the step
ey. 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 - ey this value can be changed. This
changed value has to be stored by means of the store ey. If after this,
the mode ey 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 apparatus 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 belongs to the system such as maximum flow water 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 ey again after the adjustment of the maximum flow water temperature is shown
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 - ey the desired installation type can be chosen.
The choice has to be confirmed with the store ey after which one can return by means of the mode ey to the reading or the technical
reading .

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

Replenishing or complete filling up of the installation
The installation functions at an optimum water pressure of between 1 and 2 bar. If the step ey is pushed briefly, the water pressure can
be shown. After this the waterpressure is shown. When the step ey is pushed again briefly one will return to the or
reading. When the water pressure drops below 1 bar the display will automatically show the text . This text is being
interchanged with the normal display reading . The Brain thermostat will show the text Waterpressure too low - no disorder - fill water.
Through out this the apparatus will only function at a reduced output. When the water pressure is sufficiently high again (above 1,5 bar) the
text will disappear and the apparatus will return to the normal act. If the water pressure drops further and comes below 0,7 bar the
display will show a flashing text. The Brain thermostat will show the text Waterpressure too low - disorder - fill water. After this the
apparatus is switched off and will only function again when the waterpressure comes above 1,5 bar.
Turning the apparatus off
oliday period: Adjust the Brain thermostat to the holiday period. See the thermostat manual for this operation. When there is no Brain
thermostat present the room thermostat or the regulation on the night temperature can be adjusted and the hot water
facility can be switched off by means of the program ey on the control panel.
Activities: Switch off the three program eys , , when these are activated. When the apparatus is being drained
one should ta e into account that a part of the heating water will stay in the apparatus. When the situation of frost danger
arises one should ta e care that the remaining central heating water in the apparatus will not freeze.
