General information
2.6
Connection to chimney
Existing regulations for the design of the chimney must be taken into
consideration. An optimal utilization of the flue gases and with that an
energy-saving operation, requires hereby a mostly optimized adaption
between boiler and burner.
The most important conditions are the following:
• Good thermal insulation in order to as much as possible avoid
temperature losses from the connection between the boiler and
chimney.
• Accurate sealing of the flue gas connections
• Smooth surfaces of the combustion chamber to avoid turbulence.
• Heat-shock resistance as well as water- and steamtight.
According to regulations:
• The boiler must be connected to the chimney with the shortest feasible
flue duct at an angle of 30-45°.
• The flue duct must not be fully inserted through the chimney wall.
• If flue ducts with a cross-sectional dimension which deviate from the
dimension of the flue gas outlet would be used, the connection must
be cone-shaped. Cone angle of maximum 7,5°.
• By the construction of the flue duct between boiler and chimney must
feasible actions be taken to secure that no condensate can flow back
to the boiler (condensate trap).
2.7
Flue gas temperatures
When a new boiler is being connected to an old chimney, the chimney is
often not dimensioned to the new high efficiency of the boiler, which may
easily result in condensation in the chimney depending on lower flue gas
temperatures. In order to ventilate the chimney with warmer boiler room air, a
draught interrupter can be mounted.
All boiler-sizes of the CTC 380 Ecoswiss serie has for the current output-size
design related operational flue gas temperatures. For flue gas temperature
data, see Technical information.
2.8
Hydraulic connection boiler
The dimensioning and plumbing of the system shall be accomplished
according to the measurements in the part Technical information.
2.9
Safety valve boiler
In a closed system, an approved safety valve according to existing
regulations must be mounted.
The max. Operation pressure of the boiler is 3 bars. The connection
pipebetween boiler and safety valve must be constructed in such way
that no pressure increase is possible. The safety valve drain pipe must be
uncovered and visible. Possible exhausting high-temperature hot water must
without danger be removed (Caution! Risk of scalding)

Commissioning
Prerequisites
To commission the units, the following steps must be carried out:
• Prerequisite is correct mounting and correct electrical installation and,
in the case of wireless systems, correctly working radio links to all the
auxiliary units
• Make all plant-specific settings. Special attention must be paid to
operating page ”Configuration“.
For that purpose, the relevant operating level is to be selected
as follows: Press the OK button on the operator unit to switch to
programming. Press the Info button for at least 3 seconds and select
operating level “Commissioning“ with the setting knob. Then, press the
OK button.
• Make the functional check as described below
• Reset the attenuated outside temperature (operating page “Diagnostics
of consumers“, operating line
“Outside temp attenuated“ (line 8703)))
Functional check
To facilitate commissioning and fault tracing, the controller allows output
and input tests to be made. This allows to test the outputs and inputs. To
make the tests, select operating page “Input/output test“ and go through all
available operating lines..
Operating state
The current operating state can be checked on operating page “State“.
Diagnostics
For detailed diagnostics of the plant, check operating pages “Diagnostics
heat source“ and “Diagnostics consumer”.
CTC 380 S

General information
Time programs
For the heating circuits and DHW heating, a number of switching program
are available. They are activated in “Automatic” operation and control the
change of the temperature levels via the selected switching times.
The switching times can be set in a combined way, that is, either commonly
for several days or separate times for individual days. When preselecting
groups of days like for instances Mo…Fr and Sa…Su that use the same
switching times, setting of the switching programs is simplified.
• Press the ”OK-button”
• Select “Time prog heating circuit 1” and press “OK”.
• The text “Preselection” is shown.
• Press “OK” and the selection start flashing.
• You can select between program for Mo-Su, Mo-Fr, Sa-Su, or each
day separately
• Select “1 st phase on” and press “OK”.
• The time start flashing and you can select the start time for heating
“comfort setpoint” Press “OK”
• Select “1 st phase off” and press “OK”.
• The time start flashing and you can select the stop time for heating
“comfort setpoint” Press “OK”
• Phase off means that “Reduced setpoint” is active.
• It is possible to select 3 phase for each day.
• Press “ESC” and “ESC” again.
All time programs can be reset to the default settings. Each time program
has its own operating line to make this reset.
In that case, individual settings will be lost!

CTC 380 S
General information
Heating curve
The heating curve is used to generate the flow temperature setpoint, which
is used to maintain a certain flow temperature depending on the prevailing
weather conditions.
The heating curve can be adjusted with a number of settings, thus matching
heat output and room temperature to individual needs.
As the heating curve slope is raised, the flow temperature increases the
quicker the lower the outside temperature or, in other words, if the room
temperature is not correct at low outside temperatures but correct at higher
outside temperatures, the heating curve slope requires readjustment.
Increase adjustment: Raises the flow temperature, especially when outside
temperatures are low. Decrease adjustment: Lowers the flow temperature,
especially when outside temperatures are low. Default setting 1,5
Parallel displacement of the heating curve is used to change the flow
temperature evenly across the entire outside temperature range or, in other
words, if the room temperature is always too high or too low, a readjustment
must be made with the help of the parallel displacement.
• Press the “OK-button”
• Select “Heating circuit 1” and press “OK”
• Select Menu 720 “Heating curve slope” and press “OK”
• Select setpoint and press “OK” for confirm
• Select Menu 721 “Heating curve displacement” and press “OK”
• Select setpoint and press “OK” for confirm
• Press “ESC” and “ESC” again
CTC 380 S
33
General information
Flow temperature limitation
Using this limitation, a temperature range for the flow temperature setpoint
can be defined. If the flow temperature setpoint demanded by the heating
circuit reaches the relevant limit and the heat request increases or decreases,
the flow temperature setpoint will be maintained at the maximum or
minimum limit.
If you want to have floor heating in the summer for example in a basement or
a bathroom you set the “Flow temp min” to a higher temperature.
Notice that the value for “Summer/winter setpoint stops the heating circuit at
chosen temperature, in “Automatic mode”. So you maybe have to select a
higher temperature on this as well.
To select a value for the set points do as follow:
• Press the ”OK-button”
• Press the ”i-button” for 3 seconds.
• Select “Commissioning” and press “OK”.
• Select “Heating circuit 1” and press “OK”.
• Select “Flow temp setpoint min” (Menu 740) and press “OK”
• The temperature starts flashing.
• Select a temperature for min flow temp, and press “OK” to confirm.
• Select “Flow temp setpoint max” (Menu 741) and press “OK”
• Select a temperature for max flow temp, and press “OK” to confirm.
• Press “ESC” and “ESC” again.

General information
9. Operation
9.1
General information
After the installation check together with the installer that the installation is
fully ready for operation. Let the installer show you all important regulation
devices, etc. so that you are well aware of how the boiler installation
functions and should be maintained. Vent the radiators after appr. 3 days of
operation and fill up with more water if necessary.
9.2
Regular inspection
The regular inspection should include following items:
• Check control of the pressure gauge (manometer). By too low
pressure, fill-up water in the heating system by means of charging- and
drainage device.
• Check control of the heating oil level in the tank.
• Check control of the settings of the Comfort-control.
• Check control of the temperature of the heating boiler, primary flow
and flue gas.
• Check control of the burner according to the instructions in the
technical manual from the manufacturer.
• In a closed system, check control of the safety valve by means of
either turning or lifting the regulation device of the valve. Check if water
run out from the safety valve drain pipe.
9.3
Standstill
If the installation should be put out of operation, use the mains switch.
See the part Electrical installation – Comfort-Control.
9.4
Frost risk
Never put the boiler in operation if its pose a risk that the boiler or parts
of the heating system is frozen. This leads to damages on the boiler and
piping in the house. Consult your heating technician for advice. Concerning
protection mode, see the part Electrical installation – Comfort-Control.

Boiler Cleaning
The boiler must be currentless by the boiler cleaning!
• The combustion chamber is from the front easily cleaned:
• Remove the burner hood.
• Switch off the burner.
• Pull out the burner Eurostecker.
• Undo and remove the burner door screws. The door may now be
swinged out without dismantling of the burner.
• Remove the turbulators.
• Clean the combustion chamber and heating surfaces by using the
supplied tube brushes.
• Reassemble the turbulators, close the burner door and put back the
screws and tighten after finishing the cleaning.
• Connect the burner Eurostecker and switch on the burner.
• Attach the burner hood.
The boiler installation must be regularly cleaned according to existing
regulations.
9.6
Drainage
The boiler must be currentless upon drainage. The drainage connection/
drain valve is low located on the rear side of the boiler. By drainage of the
whole system must the heating circuit mixing valve be fully open. In a closed
system air must be supplied.
9.7
Oil operation
General information: Adjustments and maintenance of the oil burner must
always be performed according to the technical manual of the burner.
In order to secure that the installation operates correctly, has low energy
consumption and minimizes the harmful emissions, is it of great importance
that maintenance with a check control in consideration of the setting values
is performed on a regularly basis (recommended annual).
