General information
Welcome
Congratulations! You have just bought a CTC EcoEl, which we hope you will be very
pleased with. In the following handbook, you can read about how to operate your
electrical boiler. One chapter is written for the property owner and one chapter for the
installation contractor.
Keep this handbook with the installation and maintenance instructions. The CTC EcoEl
is designed to last for many years, and it is here you will find the information you need
to operate and maintain the unit correctly and ensure its longevity.
The complete electrical boiler
CTC EcoEl is a complete electrical boiler which can provide your detached house’s
heating and hot water requirements. It is equipped with a motorised mixing valve valve
which ensures correct and even temperatures are supplied to your radiators.
CTC EcoEl has a control system which:
◗Monitors all functions of the electrical boiler as well as potentially connected CTC
EcoAir or CTC EcoPart heat pumps.
◗Permits individual settings.
◗Displays required values, such as temperatures, operation times, energy consumption,
and fault recording.
◗In a simple and well structured way, allows settings to be adjusted and fault tracing
Your CTC EcoEl is equipped with a built in copper coil providing copious amounts of
hot water. CTC EcoEl also has a so called summer time cellar heating function and a
floor heating block, which maximises the temperature supplied to the floor circuits.
Using the built in night time reduction function, you can set and change house tem-
peratures during the day and from day to day in the Week program.
Easily accessible electric components and good fault tracing functions in the control
program make CTC EcoEl service friendly. It is supplied with a room sensor as stand-
ard, which is equipped with a light diode which flashes in the event of a fault.
The CTC EcoEL is designed for easy connection of the air/water heat pumps CTC
EcoAir or the ground source heat pump CTC EcoPart. When connected the complete
functions of the heat pump are controlled from the CTC EcoEl control system and
menu display.

General information
!The set heating curve
is always prioritised.
The room sensor can
only call on the mixing
valve to increase temper-
atures to a specific level
beyond the set heating
curve. Where operating
without a room sensor,
the selected graph de-
termines the temperature
supplied to the radiators.
Heating curve
The heating curve is a central part of the product’s control system. It is the heating
curve which determines the temperature requirement for your property at different
outdoor temperatures. It is important that the heating curve is correctly adjusted, so
that you achieve the best function and economy possible.
One property requires a radiator temperature of 30°C when the outdoor temperature
is 0°C. A different property requires 40°C. The difference between different properties
is determined by radiator surface area, the number of radiators and how well insulated
the house is.
Adjustment of heating curve basic values
The heating curve for your property is set using two values in the product control
system. This is set in the menu Installer/Settings/Setting house paramt/
Inclination and Adjustment.
Arriving at the correct heating curve can take some time. The best way to achieve this
is to select operation without room sensor in the initial period. The system then oper-
ates using outdoor temperatures only.
During the adjustment period it is important that:
◗Night reduction function is not selected.
◗All radiator thermostat valves are fully open.
◗Outdoor temperature is not higher than +5°C. (If the outdoor temperature is
higher when the system is installed, use the factory set graph until the outdoor
temperature falls to this level.)
◗The radiator system functions well and is correctly adjusted for the different
circuits.
Inclination and adjustment
Inclination 50:
The value defies the outgoing temperature of the water supplied to the radiators at an
outdoor temperature of –15°C, e.g. 50°C.
A lower value is set where a radiator system has larger radiator areas (a low temperature
system).
Floor heating systems require much lower temperatures. An even lower value should
therefore be selected.
The value must be increased for high temperature systems to achieve high enough in-
door temperatures.
Adjustment 0:
The inclination defines how much the temperature of the water supplied to the radia-
tors should be increased for falling outdoor temperatures. The adjustment specifies that
the temperature level can be raised or be lowered at specific outdoor temperatures.
Example:
Inclination 50 means that the temperature of the water supplied to the radiators is 50°C when
the outdoor temperature is –15°C (if adjustment is set to 0). If the adjustment is set to +5, the
temperature is instead 55°C.
The graph is increased by 5°C at all temperatures, i.e. the graph is parallel displaced by 5°C.

General information
Examples of heating curves
Below you find three charts where you can see how the heating curve changes by differ-
ent settings of the Inclination. The gradient of the curve shows which temperature the
heating system requires at different outdoor temperatures.

General information
!To low adjusted values
might imply that the re-
quired indoor tempera-
ture is not being reached.
Then you have to adjust
the heating curve accord-
ing to need.
Suitable standard values
At the time of the installation it is seldom possible to instantly set the heating curve
exactly . The values to the right may then be a good starting-point before the more ac-
curate adjustment is set.
Radiators with small heat emission surfaces require higher primary flow temperatures.
Menu:
Installer/Settings/Setting house paramt ----->Inclination
Floor heating only Inclination 35
Low temperature system (well insulated house) Inclination 40
Standard temperature system (older house) Inclination 50
High temperature system
(older house, small radiators, poorly insulated) Inclination 60
Adjustment (if the outdoor temperature is lower than 0 degrees)
◗At too cold indoors: Increase the value at Inclination a couple of degrees.
Wait one day before the next adjustment.
◗At too warm indoors: Decrease the value at Inclination
a couple of degrees. Wait one day before the next adjustment.
Adjustment (if the outdoor temperature is higher than 0 degrees)
◗At too cold indoors: Increase the value at Adjustment a couple of degrees.
Wait one day before the next adjustment.
◗At too warm indoors: Decrease the value at Adjustment

values are fairly correct
adjusted, the curve can
be displaced directly in

General information
Construction EcoEl
The picture below shows the fundamental construction of the product.
Fresh water connections
Here you connect the fresh
water connections of the
property. The cold water is
led down to the lower part of
the coil.
Gilled coil for hot water
The product is equipped with a well dimensioned
gilled coil in copper. The product is not supplied
with any parts which can rust and break. The
temperature can be kept low without risk of
legionella bacteria.
Bivalent mixing valve
The automatized mixing valve
ensures that an even heat
reaches the radiator system
continously. The valve has
double doors and first collects
the hot radiator water from the
water heated by the heating
pump.
Upper part
In the upper part of the coil the
water is heated to the selected
hot water temperature.
Immersion heaters
A built-in immersion heater
functions as peak heat if the
effective output is not sufficient
along with the rising of the hot
water temperature.
Lower part
In the lower part of the coil the
water is pre-heated by the heat
pump. The major part of the coil
is located in this part.
!Note: Do not connect
the product accord-
ing to this construc-
tion sketch, see instead
the measurements on
page 30 and the chapter
”Plumbing system”.
Drainage valve
Used for drainage of the pro-
duct and/or radiator system.
When EcoEl connected to heat
pump, this would be the flow
pipe to the heat pump.
Insulation
The tank of the boiler is
insulated with die cast
polyurethane foam for
minimal heat losses.
Connection for heat pump
When EcoEl connected to heat
pump, this would be the flow
pipe from the heat pump.

The room temperature is set in this menu if a room sensor has not been fitted
(selected in the settings menu). The house’s basic settings are first set in the
“house parameters” menu, usually with the help of the installation contractor.
Basic settings are then fine tuned using this menu.
If the indoor temperature is experienced as being too low or too high, move the
cursor towards + (increase) or – (reduce). Move a little at a time and see what effect
this has on indoor temperatures (1 day) before making further changes. Several ad-
justments may be necessary at different outdoor temperatures. However, a correct
setting will be arrived at which will not require further changing. A reference value
(for example 50) is displayed under the bar. This value depends on the basic value
set. If the bar does not extend far enough to allow the correct indoor temperature
to be obtained, the basic setting must be adjusted in the Installer/Settings/Setting
house paramet. The cursor is then centred in relation to the new values.
NOTE: radiator thermostats must be fully open and fully functioning
when adjusting the system.

Menu Operation data (the menu is directly accessed from the
main menu)
This menu displays current product and system temperatures and operating data.
Values in brackets are either required values or automatically generated values
which the product aims to achieve (expected values).
Outdoor °C -5 Displays current outdoor temperature.
The product uses this value to determine a number of different operating data.
Boiler°C 47 (56) Displays the upper boiler section temperature (electric boiler) and the temperature
which the boiler aims to achieve. This value automatically increases if a poor radiator
system requires higher temperatures.
Primfl °C 47 (49) Displays the temperature of the water supplied to the house’s radiators, and the
temperature which the system aims to achieve. This value will vary during operation
depending on set parameters and current outdoor temperatures.
Boiler lower °C 48 (50) Displays the lower boiler section temperature (electric boiler) and the temperature
which the boiler aims to achieve.
Heatingcir.pump Displays the heating circuit (radiator) pump’s operating status. The pump stops in
On/Off the summer time when there is no heating requirement. The pump is however
exercised occasionally to avoid it jamming.
El power kW 6.0 Displays auxiliary power of the electric boiler (0…9 kW).
The electric boiler connects power in steps of 1.5 kW (6 connection steps).
Current A 11 (20) Displays the house’s total current consumption on the hardest loaded phase. The
house’s main fuse size is displayed in brackets. Assumes that the current sensor
upplied has been fitted to the incoming cables. If the current drawn exceeds the
main fuse size, the electric boiler automatically steps down a power step to protect
the fuses, for example when several high consumption equipment units in the house
are being used.
Mixing valve A micro switch in the mixing valve valve’s motor ensures that auxiliary heating is not
used unnecessarily.

Menu Night reduction (the menu can be directly accessed
from the main menu)
Night time lowering of temperatures can be activated and set in this menu.
Night time temperature lowering means that the indoor temperature is lowered
during scheduled periods, for example at night or when you are at work. Two
types of night time temperature lowering can be selected. Week Program is se-
lected to schedule daily lowering of temperatures. Block is selected to schedule
night temperature lowering periods which last for several days.
Activated Yes/No Here you can select whether scheduled temperature lowering is active. Where “No”
is selected, there is no temperature lowering.
Typ WeekProgram The type of lowering is selected here:
WeekProgram means that periods of lower temperatures can be scheduled for all
days of the week, with the option of two periods of lower temperatures per day.
The schedule repeats every week.
Block means that lowering is scheduled for several days of the week, for example
Monday to Friday. Two lower temperature periods can be scheduled.
The schedule repeats every week.
Prim red °C -5 Here you can set how many degrees the room temperature is to be lowered during
the lower temperature periods. NB: –5 means that the room temperature is lowe
red 5°C below the ordinary temp. If the room sensor is not included in operation,
the lowering is applied to the primary flow temperature. Rule of thumb: a 3–4°C
lower primary flow temperature gives around 1°C lower room temp in a normal
system.
WeekProgram or Block Scheduling is set under these menus, see next section.
