Congratulations on buying your new product
You have just bought a CTC EcoZenith i250, which
we hope you will be very pleased with. In the following
pages you can read about how to operate and maintain
your boiler. One chapter is written for the property
owner and one chapter for the installer.
Keep this manual containing the installation and
maintenance instructions. If it is properly maintained,
you will be able to enjoy the use of your CTC EcoZenith
i250 for many years. This manual will provide all the
information you will need.
The complete system tank
The CTC EcoZenith i250 is a complete system tank
which meets your home’s heating and hot water
requirements. It has a built-in immersion heater giving a
total of 15 kW and is equipped with a motorised mixing
valve which ensures correct and even temperatures are
supplied to your heating system. The CTC EcoZenith
i250 has a built-in circulation pump for connection to a
heat pump.
The CTC EcoZenith i250 is fully designed to work with
the CTC EcoAir 406-410 outdoor air heat pump or
CTC EcoPart 406-410 bedrock/ground source heat
pump. CTC EcoPart 412 can also be connected to the
EcoZenith i250 provided that the function "exact primary
flow" is activated. All controls for the heat pump and
charge pump are built into the CTC EcoZenith i250.
With this added feature you achieve a very eco-friendly
and energy-saving heating system.
For more information, please see the separate section in
this manual.
The CTC EcoZenith i250 has a control

system functions
• Permits individual settings
• Displays desired values, such as temperatures,
operation times, energy consumption and fault
signals
• Facilitates the setting of values and troubleshooting
in a simple and well-structured way
The built-in copper coil provides copious amounts of
hot water. The CTC EcoZenith i250 also has a socalled summer-time basement heating function and a
floor heating block, which maximises the temperature
supplied to the floor circuits. Using the integrated
night reduction function, you can set and change the
temperature in the house during the day, from one day
to the next.
Easily accessible electrical components, along with
effective troubleshooting functions in the control
program, make the CTC EcoZenith i250 easy to service.
It comes with a room sensor as standard, which is
equipped with an LED which flashes in the event of a
fault.

The House Heating Curve
The heating curve is the central part of the product’s control system. It is the heating
curve which determines the compensated flow temperature requirements for your
property dependent upon the outdoor temperatures. It is important that the heating
curve is correctly adjusted, so that you achieve the best operation and economy
possible.
One property requires a radiator temperature of 30 °C when the outdoor temperature
is 0 °C, whilst a different property requires 40 °C. The difference between different
properties is determined by the radiator surface area, the number of radiators and how
well insulated the house is.
!
The set heating curve is always given priority. The room sensor can only increase
or decrease the compensated flow temperature to a certain extent above the set
heating curve. Where operating without a room sensor, the selected heating curve
determines the flow temperature supplied to the radiators purely from the outside
temperature reading.
Adjustment of Default Values for the Heating Curve
You define the heating curve yourself for your property by setting two values in
the product control system. This is achieved by selecting the options Inclination or
Adjustment under the Installer/Settings/Radiator system menu. Ask your installer to
help you set these values.
It is extremely important to set the heating curve and, in some cases, unfortunately,
this process may take several weeks. The best way of doing this, upon the initial
start-up, is to select operation without any room sensor. The system then operates
using the outdoor temperature reading and the property’s heating curve only.
During the adjustment period it is important that:
• the night reduction function is not selected.
• all thermostat valves on the radiators be fully opened.
• the outdoor temperature is not higher than +5 °C. (If the outdoor temperature is
higher when the system is installed, use the factory set curve until the outdoor
temperature falls to a suitable level.)
• the radiator system is operational and correctly adjusted between different
circuits.
Appropriate Default Values
During installation you can seldom achieve a precise setting for the heating
curve instantly. In this case, the values given below may provide a good starting
point. Radiators with small heat-emission surfaces require a higher primary flow
temperature. You can adjust the gradient (heating curve gradient) for your heating
system under the Installer/Settings/Radiator system menu.
Recommended values are:
8
Floor heating only
Inclination 35
Low temperature system (well insulated houses)
Inclination 40
Normal temperature system (factory setting)
Inclination 50
High temperature system
(older houses, small radiators, poorly insulated)
Inclination 60
CTC EcoZenith i250
General Information
Adjusting the heating curve
The method described below can be used to adjust the heating curve correctly.
Adjustment if it is too cold indoors
• If the outdoor temperature is lower than 0 degrees:
Increase the Inclination value by a couple of degrees.
Wait 24 hours to see if any further adjustment is required.
• If the outdoor temperature is higher than 0 degrees:
Increase the Adjustment value by a couple of degrees.
Wait 24 hours to see if any further adjustment is required.
Adjustment if it is too warm indoors
• If the outdoor temperature is lower than 0 degrees:
Decrease the Inclination value by a couple of degrees.
Wait 24 hours to see if any further adjustment is required.
• If the outdoor temperature is higher than 0 degrees:
Decrease the Adjustment value by a couple of degrees.
Wait 24 hours to see if any further adjustment is required.
!
If the values set are too low, this may mean that the desired room temperature
is not being reached. You then need to adjust the heating curve, as necessary,
following the method shown above.
When the basic values have been set more or less correctly, the curve can be
finely adjusted directly using the Room temp. shown on the home menu screen.
Description of inclination and adjustment
Inclination 50:
The value set is 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 selected where a radiator
system has large radiator areas (a low temperature system). Floor heating systems
require low temperatures. A low value should therefore be selected. The value must be
increased for high temperature systems to achieve a high enough indoor temperature.
Adjustment 0:
The adjustment means that the flow temperature can be raised or lowered at a specific
outdoor temperature.
Adjustment 0 means 50 °C primary flow when the outside temperature is -15 °C.
Adjustment -5 means 45 °C primary flow when the outside temperature is -15 °C.
For example:
Inclination 50 means that the temperature of the water supplied to the radiators will
be 50 °C when the outdoor temperature is –15 °C (if adjustment is set to 0). If the
adjustment is set to +5, the temperature will be 55 °C instead. The curve is increased
by 5 °C at all temperatures, i.e. it is parallel displaced by 5 °C.

General Information
Examples of Heating Curves
You can see in the diagram below how the heating curve
changes with different Inclination settings. The gradient of
the curve shows the temperatures that the radiators require
at different outdoor temperatures.
Primary Flow Temperature
Curve Inclination
The inclination value which is set is the primary flow
temperature when the outside temperature is –15 °C.
Outside Temperature
Heating off, out
Adjustment
The curve can be parallel displaced (adjusted) by the
desired number of degrees to adapt to different systems/
houses.
Inclination 50 °C
Adjustment +5 °C
Primary Flow Temperature
Inclination 50 °C
Adjustment 0 °C
Outside Temperature
Heating off, out
An example
Inclination 60 °C
Adjustment 0 °C
Primary Flow Temperature
In this example, the maximum outgoing primary flow
temperature is set at 55 °C.
The minimum permitted primary flow temperature is 27 °C
(e.g. summer-time basement heating or the floor circuits in
a bathroom).
Outside Temperature
Summer-time operation
All properties have internal heat gains (lamps, oven,
personal heat etc.), which means that the heating can be
switched off when the outdoor temperature is lower than
the desired room temperature. The better insulated the
house is, the earlier the heating from the heat pump can be
switched off.
The example shows the product set at the default value of
18 °C. This Heating off value can be changed under the
Installer/Settings/Radiator system menu.
When the heat is switched off in this way, the radiator
pump stops and the mixing valve is shut down. The heating
starts up automatically when it is required again.

General Information
4. CTC EcoZenith i250 design
The picture below shows the basic construction of CTC EcoZenith i250.
If a heat pump is connected, the energy in the air or bedrock/ground is drawn
up by the cooling system. The compressor then increases the temperature to
a usable level. Afterwards it releases the energy for the heating system and
hot water. The built-in immersion heaters help when additional heat is needed
or when a heat pump is not connected.
Fresh Water Connections
The property’s fresh water
supply is connected here.
The cold water is fed down
and heated in the lower part
of the coiling.
Upper part
In the upper part of the coil
the hot water is then heated
to the desired temperature.
Finned Coil for Hot Water
The EcoZenith i250 is
equipped with a welldimensioned finned coil made
of copper. Since hot water is
not stored, there is no risk of
legionella bacteria.
Upper immersion heater
Built-in upper immersion
heater. When connected to
a heat pump, the immersion
heater acts as additional heat.
Lower immersion heater
Built-in lower immersion
heater. Not used in normal
operation when the heat
pump is connected.
Draining/expansion vessel
connection
Two connections in the
lower part of the product
where water from the boiler
and radiator system can be
drained.
14
CTC EcoZenith i250
Bivalent Mixing Valve
The automated mixing valve
ensures that an even heat is
continuously supplied to the
radiator system.
Insulation
The heat pump’s tank is
insulated with die-cast
polyurethane foam for minimal
heat loss.
Lower part
In the lower part of the coil
the hot water is pre-heated by
the water heated by the heat
pump. The major section of
the coil is located in this part.
Expansion connection
15 mm.
Diverting valve
The heated water from the
heat pump heats up the
upper or lower part of the
tank alternately.
Heat medium pump
The adjustable-speed charge
pump transports the cold
water from the boiler to the
heat pump where the energy
from the air or bedrock/ground
is drawn up and taken back to
the boiler.

Factory values
The CTC EcoZenith i250 is delivered with set factory
values which are suitable for a standard house with
a standard radiator system. The CTC EcoZenith i250
automatically adjusts the water temperature to the
primary flow’s current heating requirement. This is
monitored by the control system, which continuously
ensures that you are provided with optimum function
and economy. These values are easy to change as and
when required. Ask your installer to help you determine
the correct values.
Heat pump
On delivery the CTC EcoZenith i250 is ready for
connection to a CTC heat pump, CTC EcoAir 400
outdoor air heat pump or CTC EcoPart 400 bedrock/
ground source heat pump.
This means that the control system already contains all
the controls for the heat pump. When the heat pump
is defined, the EcoZenith i250 automatically goes to
heat pump operation. Once this has taken place the
menus for the heat pump are displayed. On delivery the
compressor is blocked and must be set to permitted.
This is done under the Installer/Settings/Heat pump
menu.

Heating circuit 1
This is used to set the desired room temperature. Use
the plus and minus buttons to set the temperature you
want, which gives you the “setpoint” temperature, in
brackets. You can see the current value next to the
brackets.
If two radiator systems are installed, the values for both
are displayed.
Night reduction
Night reduction
1
If you want to schedule a temperature reduction, you
can continue to the Night reduction or Holiday submenus.
You can select Room sensor No under the Installer/
Define system/Radiator system menu. This can be
done if the room sensor is poorly positioned, if the floor
heating system has a separate room sensor or if you
use a fire place or open stove. The alarm LED on the
room sensor still functions as normal.
If you use the fire or open stove only occasionally, the
firing process can affect the room sensor and reduce
the temperature supplied to the radiators. It can then
get cold in the rooms in other parts of the house. The
room sensor can temporarily be deselected during the
firing process. The EcoZenith i250 then provides heating
to the radiators using the set heating curve. The radiator
thermostats reduce the heating supplied to the section
of the house where a fire is burning.

8.3.1 Setting temperature without a
room sensor
If a room sensor has not been installed (selected in
the Settings menu), you use this option to adjust the
room temperature by trimming the flow temperature.
If this range is not sufficient, the basic setting must be
adjusted under the Installer/Settings/Radiator system
menu.
Change the value in small steps each time (approx. 2
to 3 steps) and wait for the result (approx. one day), as
there is a delay in the system responding.
Several adjustments may be necessary at different
outdoor temperatures, but you will gradually achieve the
right setting that will not need to be changed.

For example:
“Inclination 50” means that the temperature of the water
supplied to the radiators will be 50°C when the outdoor
temperature is -15°C, if the adjustment is set to 0. If the
adjustment is set to +5, the temperature will be 55°C
instead. The curve is increased by 5°C at all outdoor
temperatures, i.e. the curve is parallel offset by 5°C.

Inclination (default setting)
Inclination means the temperature your property needs
at different outdoor temperatures. See more detailed
information about this in the chapter on Your property’s
heating installation. The value set is the outgoing flow
temperature to radiators when the outdoor temperature
is -15 °C. After this default setting, fine adjustment takes
place in the “Room temperature” menu.

Exact primary flow means that the heat pump never
switches over and heats the upper tank (hot water
charging). This is provided solely by the electric heater.
In summer mode however, i.e. if the outdoor

heat pump will be allowed to send water to the upper
tank.

Electric heater
Temperature when the immersion heater kicks in
and helps EcoZenith i250 to produce domestic hot
water when there is great demand. A low setting is
recommended.
The immersion heater is also responsible for providing
the house with additional heating. If the house requires
a higher temperature than that selected, the control
system compensates by automatically raising the
temperature of the immersion heaters.

General Information
9. Operation and
Maintenance
When the installer has installed your new system, you should check along
with the installer that it is in perfect operating condition. Let the installer show
you where the switches, controls and fuses are so that you know how the
system works and how it should be maintained. Bleed the radiators after
around three days of operation and top up with water if required.
Boiler and radiator system safety valve
Check around four times a year that the valve is working by manually turning
the control. Check that water is coming out of the safety valve discharge.
Mixing Valve
increase
The mixing valve is operated automatically from the control system, ensuring
that the radiators reach the correct temperature, no matter what season it
is. However, where a fault occurs, you can operate the valve by pulling out
the knob on the motor and turning it clockwise to reduce the temperature or
anticlockwise to increase it.
Draining the tank
The CTC EcoZenith should be disconnected from the power source when
it is being drained. The drain valve is positioned at the bottom left of the
unit when viewed from the front, behind the front of EcoZenith. When
draining the whole system, the mixing valve should be fully open, i.e. turned
anticlockwise as far as it will go. Air must be supplied to the closed system.
Shut-down
The CTC EcoZenith i250 is shut down using the operating switch. If there
is a risk of the water freezing, all the water should be drained from the heat
pump and the radiator system (see drainage above).
The DHW circuit, which contains around five litres, must also be emptied.
Disconnect the cold water connection to CTC EcoZenith i250. Feed a hose
into the cold water connection to CTC EcoZenith i250. The hose must go
down to the bottom of the coil for all the water to be drained. Draining is
carried out by siphoning out the water.

General Information
10. Troubleshooting/measures
The CTC EcoZenith i250 is designed to provide reliable operation and high
levels of comfort, and to have a long service life. Various tips are given
below which may be helpful and guide you in the event of an operational
malfunction.
If a fault occurs, you should always contact the installer who installed your
unit. If the installer believes the malfunction is due to a materials or design
fault, then they will contact us to check and rectify the issue. Always provide
the product’s serial number.
DHW
Many people want to gain maximum benefit from the CTC EcoZenith i250’s
low operating costs.
The control system is equipped with three comfort levels for hot water. We
recommend starting at the lowest level and if there is not enough hot water,
increase it to the next level. We also recommend that you operate a regular
hot water pattern.
Check that the hot water temperature is not being affected by a poor mixing
valve, whether in the CTC EcoZenith i250 or possibly the shower mixer.
The Heating System
A room sensor, which should be fitted when possible, ensures that the
temperature in the room is always suitable and stable. For the sensor to
provide the correct signals to the control unit, radiator thermostats should
always be fully open in the area where the room sensor is located.
A correctly operating heating system is of significant importance to the heat
pump’s operation and affects energy savings.
When adjusting the system, always do so with all radiator thermostats fully
open. The thermostats can be individually adjusted after a few days in the
other rooms.
!
!
!
Avoid running hot
water at the highest
flow capacity. If you
run a bath at a rather
slower rate instead,
you will get a higher
temperature.
Avoid placing the
room sensor close
to the stairway due
to the uneven air
circulation.
If you do not have
radiator thermostats
on the upper floor,
you may need to
install them.
CTC EcoZenith i250

General Information
If you do not achieve the set room temperature, check:
• that the radiator system is correctly adjusted and is functioning
normally. that radiator thermostats are open and the radiators are
equally warm all over. Touch the entire radiator surface. Bleed the
radiators. The CTC EcoZenith i250's economical operation requires that
the radiator system functions well, if you are to make good savings.
• that EcoZenith is operating and no error messages are displayed.
• that there is sufficient electrical power available. Increase if necessary.
Also check that the electric power output is not limited due to
excessively high electricity loads in the property (load monitor).
Vent valve
• that the product is not set to the “Max. allowed primary flow
temperature” mode with a too low set value.
• that “Primary flow temperature at –15°C outdoor temperature” is set
sufficiently high. Increase if necessary. More can be read about this in
the chapter on The house heating curve. However, always check the
other points first.
• that the temperature set back is not maladjusted. See Settings/Radiator
system.
• that the mixing valve is not in the manual position.
If the heat is not even, check:
• that the placement of the room sensors is appropriate for the house.
• that the radiator thermostats don't interfere with the room sensor.
• that no other heat sources/cold sources interfere with the room sensor.
• that the mixing valve is not in the manual position.

CTC EcoZenith i250
!
Don’t forget that the
radiators may also
need bleeding.
General Information
Current Monitor
The CTC EcoZenith i250 has an integrated current monitor. If the system
is fitted with a current sensor, the property’s main fuses are continuously
monitored to ensure they are not overloaded. If this should happen, electric
stages are disconnected from the CTC EcoZenith.
The CTC EcoZenith i250 may be restricted where high heating requirement
levels are combined with, for example, single-phase motor heaters, cookers,
washing machines or tumble dryers. This may result in inadequate heating
or hot water temperatures. If the CTC EcoZenith is restricted, “High current,
elpower redu (X A)” appears in text form in the display. Consult an electrician
to determine whether the fuse size is correct or the three phases in the
house are evenly loaded.
Air problems
If you hear a rasping sound from the tank, check that it has been properly
bled. Turn the boiler vent valve so that any air can be evacuated. Top up with
water where required, so that the correct pressure is achieved. If this noise
recurs, call a technician to check the cause.
Unusual noise when shutting off DHW
In some cases, unusual noises may be produced by the house's pipe
system and the CTC EcoZenith i250 due to the jolts which occur when the
flow is quickly interrupted. There is no fault with the product, but the noise
may occur when older model outlets are used. More recent outlets are
often fitted with a soft-closing mechanism. If an unusual sound comes from
hard-closing dishwasher and washing machines, this can be remedied using
a shock arrestor. A shock arrestor can also be an alternative to soft-closing
water taps.
Motor protection (when heat pump is connected)
The CTC EcoZenith i250 constantly monitors the compressor’s operating
current and an alarm is triggered if the compressor is using an unusually high
current. When a fault occurs the message "Motor protect high current" is
displayed.
The cause of the fault may be as follows:
• Phase failure or mains interruption. Check the fuses, which are the
most common cause.
• Compressor overload. Call out a service engineer.
• Faulty compressor. Call out a service engineer.
• Circulation too poor between the cooling circuit and cylinder. Check the
heat medium pump (left pump, viewed from front).
• Abnormally high temperature in the brine circuit. Call out a service
engineer.

General Information
10.1 Information messages
Information messages are displayed when appropriate and are intended to
inform users about various operational situations.
Start delay
Start delay
The compressor is not allowed to start too quickly when it has stopped. The
delay is usually approx. 10 minutes.
Heating off, radiator sys
Shows that the product is operating in summer-time mode when only hot
water is required, not heating.
Ripple control
Shows that ripple control is active. Ripple control is a device which an
electricity provider can fit with the aim of disconnecting high current draw
equipment requiring power for a short period of time. Not currently in use
in the UK. The compressor and electrical power are blocked when ripple
control is active.
High current, reduced electricity (xA)
The property's main fuses are overloaded due to the fact, for instance, that
several appliances requiring power are being used simultaneously. The
product reduces the electric heaters' electrical output over time.
Tariff, HP off.
This is used when a dual tariff is used with lower energy costs at set hours of
the day. The heat pump can then take advantage of reduced primary energy
costs.
Tariff, EL, off.
This is used when a dual tariff is used with lower energy costs at set hours of
the day. The heat pump can then take advantage of reduced primary energy
costs.
Compressor blocked
The compressor is set to be shut down, e.g. before drilling or digging
has been carried out for the collector loops. The product comes with the
compressor shut off. This option is selected under the Installer/Settings/Heat
pump menu.

10.2 Alarm messages
Alarm: Wrong phase order
compressor
Reset alarm
If a fault occurs with a sensor, for instance, an alarm is triggered. A message
appears on the display informing about the fault.
You reset the alarm by pressing the Reset alarm button on the display.
If several alarms are triggered, they are displayed one after the other. An
outstanding fault cannot be reset without being rectified first. Some alarms
are reset automatically if the fault disappears.
The description below also includes an alarm for connected heat pump.
Alarm text
Description
Wrong phase order
compressor
The product’s compressor motor must rotate in the right direction. The
product checks that the phases are connected correctly; otherwise, an
alarm is triggered. In this case, two of the phases to the product need to be
changed. The power supply to the system must be shut off when rectifying
this fault. This fault generally only occurs during installation.
Alarm sensor
An alarm is displayed if a fault occurs with a sensor that is not connected or
has short-circuited and if the value is outside the sensor's range. If this sensor
is significant to the system's operation, the compressor stops. In this case, the
alarm is reset manually after the fault has been rectified. For these sensors the
alarm is reset automatically after correction:
Sensor upper tank (B5), Sensor lower tank (B6), Sensor prim flow 1 (B1),
Sensor prim flow 2 (B2), Sensor out (B15), Room sensor 1 (B11), Room
sensor 2 (B12), Sensor brine out, Sensor brine in, Sensor HPin, Sensor HPout,
Sensor discharge, Sensor suction gas, Sensor high pressure, Sensor low
pressure.
Motor protect compressor
High/low current has been detected to the compressor. Press reset and
check whether the alarm recurs. If the fault recurs, contact your installer.
High pressure switch
The refrigerant's high pressure switch has been triggered. Press reset and
check whether the alarm recurs. If the fault recurs, contact your installer.
Low brine temp
Incoming brine temperatures from borehole/ground loop are too low. Press
reset and check whether the alarm recurs. If the fault recurs, contact your
installer to check the dimensions of the cold side.
High brine temp
Incoming brine temperatures from borehole/ground circuits are too high. Press
reset and check whether the alarm recurs. If the fault recurs, contact your
installer to check the heat source.
Excessively high brine circuit temperatures over a long period can damage the
compressor.
Low brine flow
Low brine flow is very often due to air in the collector system, particularly just
after installation. Collectors which are too long can also be a cause. Check
also that the brine pump is set to speed 3. Press reset and check whether the
alarm recurs. Also check the brine filter that has been installed.
If the fault recurs, contact your installer.

Installation
Expansion vessel connection
The CTC EcoZenith i250 is best connected to a closed expansion vessel.
The CTC EcoZenith i250 is designed to be fitted to an 18 l closed expansion
vessel. The expansion vessel is either fitted in the area under the tank or on
top of the product (see pictures). The expansion vessel with installation kit is
available as an accessory.
Expansion vessel
for installation
above the tank.
!
Expansion vessel
for installation
under the tank.
NB: If the heat pump is not connected, the connections not being used must be
capped off!
If you use an open system, the distance between the expansion vessel
and the highest placed radiator must not exceed 2.5 m in order to avoid
introducing oxygen into the system.
Note that no hot water circulation may be connected as it affects the
function of the EcoZenith and the system. If the EcoZenith i250 is connected
to another heat source, e.g. an existing boiler, the installations must have
separate expansion vessels.
Water taps
In some cases, unusual noises may be produced by the house’s pipe
system and the EcoZenith i250 due to the jolts which occur when the flow
is quickly interrupted. There is no fault with the product, but the noise may
occur when older model outlets are used. More recent outlets are often fitted
with a soft-closing mechanism. Alternatively, a shock arrestor can be fitted.
Keeping the jolting to a minimum also helps avoid unnecessary wear and
tear affecting the DHW system.

Installation
12.3 Connection to heat pump
The heat pump can be connected on the sides, back, underneath or on
top. At least Ø22 mm copper pipe must be used when connecting the
CTC EcoZenith i250 to the CTC EcoAir 406-410 and CTC EcoPart 406-410
heat pumps. CTC EcoPart 412 can also be connected to EcoZenith i250
providing that the function exact primary flow is activated. The charge pump
for the heat pumps is factory-installed in the CTC EcoZenith i250L.
The CTC EcoZenith i250 L has pipes at the rear right edge for connection of
the heat pump.
CTC EcoAir's lower connection (5) is connected to the right connection (2)
when viewed from the front, so that water is pumped out to the heat pump.
CTC EcoAir's upper connection (4) is thus connected to the left connection
(1).
The CTC EcoZenith i250 H heat pump is connected directly to the provided
charge pump located under the tank. The heat pump’s lower connection (5)
must be connected to the charge pump (3) so that water is pumped out to
the heat pump. The heat pump’s upper connection is connected to the right
diverting valve (viewed from the front).
Draining: A drain valve must be fitted to the EcoZenith’s left connection
(where the charge pump is mounted). It functions as drainage for both the
boiler and the radiator system.

12.5 External systems (solar
heating, pool heating)
The product is adapted for the connection of external
systems for energy supply or heat extraction. In order
to avoid damage to the product, it is important that
any external system is hydraulically separated through
a plate heat exchanger. The connection is made to the
front of the unit behind the front panel. Two capped
water connections each with 3/4” internal threads
suitable for right-angle connectors (3/4” – 22 mm) are
situated to the right. Insulated 22 mm copper piping is
used to form an outlet through suitably made openings
in the top cover.
When an energy supply system (e.g. solar heating) is
connected, the water for the solar heating system must
be drawn from the lower connection and returned via
the upper connection.
NOTE: Solar panels are connected with an intermediate
heat exchanger; a solar coil is not built into the CTC
EcoZenith i250.
When a heat extraction system is used (e.g. pool
heating), the water must be drawn from the upper
connection and returned via the lower connection.

Connecting external systems can seriously affect the EcoZenith’s operation and
performance and can therefore produce undesirable effects if the system is not
installed correctly.
If you are unsure how to make the connection, contact CTC for suggestions on
how to install the system.

13. Electrical installation
Installation and connection in the CTC EcoZenith i250 must be undertaken
by an authorised electrician. All wiring must be installed according to
applicable regulations. The boiler is internally connected by the factory and
set for a 5.5 + 6.0 kW power output. Depending on the country in which
CTC EcoZenith i250 is to be installed, it is available with a 400 V or 230 V
electrical connection.
Electrical connections are made behind the product's front panel. Undo
the screws on the top (2 screws), bend out and put the front to one side
(disconnect any network cables on the front printed circuit card for easier
access). The terminal blocks are located behind the electrical
connection box cover. Connection cables are inserted in the cable ducts
on the unit’s top cover, which exit at the same height as the bottom of the
electrical connections box. Sensor cables are inserted separately as far as
possible through the cable ducts to the right of the product’s top cover.
Safety switch
The installation should be preceded by a dual pole isolating safety switch
which ensures disconnection from all electric power sources.

13.5 Extra low voltage protection
The following outputs and inputs have extra low voltage protection: current
transformer, outdoor sensor, room sensor, primary flow sensor, return
sensor, NR/SO, temperature sensor, level switch and PWM signals.
Connection of outdoor sensor (B15)
The sensor should be set up on the house’s northwest or north side, so that
it is not exposed to morning and evening sun. If there is a risk of the sensor
being affected by the sun’s rays, it must be protected by a screen.
Place the sensor at around 2/3 of the height of the facade near a corner, but
not under a roof projection or other form of wind protection. Do not place it
either above ventilation ducts, doors or windows where the sensor may be
affected by factors other than the actual outdoor temperature.
!
Do not attach the
sensor cable permanently until you have
tested where the
best location is.
Connection of room sensor (B11) (B12)
The room sensor is fitted at a central point in the house, in the most open
position possible, ideally in a hall between several rooms. This is the best
position for the sensor to record an average temperature for the house.
Feed a three-conductor cable (minimum 0.5 mm2) between the heat pump
and room sensor. Then attach the room sensor securely in a position at
roughly two thirds of the way up the wall. Connect the cable to the room
sensor and EcoZenith.
Connection of primary flow sensor (B1, B2) /return sensor
(B7)
Fit the primary flow sensor to the primary flow pipe, ideally after the
circulation pump. Fit the return sensor to the return pipe.
The sensing part is towards the end of the sensor (see sketch).

Installation
13.5.1 Remote-controlled temperature reduction
The night temperature reduction function can be activated via a closed
function on the electricity remote control input, pins G33 and G34 on the
terminal board. The function can be controlled remotely using “Minicall”, for
instance.
While the input is short circuited, the temperature reduction is activated,
regardless of other settings. When the short circuit ceases, the product
returns to ordinary settings.
The size of the reduction is set in the menu: Installer/Settings/Radiator
system/Prim reduced.
NOTE: the input function can be selected according to the following:
• NR = Night reduction of temperature (time-controlled lowering of
temperature)
• SO = Shut off (compressor and power output blocked by the electricity
supplier)
• DHW = Extra hot water button (accessory)
13.5.2Current sensor connection
The three current sensors (designated current transformer on the connection
block), one for each phase, are fitted on the fuse panel in the following
manner.
Each phase from the electricity distribution board supplying the EcoHeat
is channelled through a current sensor before termination at the relevant
terminal. Then connect to the boiler based on the terminal board diagram.
This allows the phase current to be sensed all the time and compared with
the value set for the EcoZenith’s current monitor. If the current is higher, the
control unit drops to a lower heat output. If it is still too high, further reduction
in output takes place.
When the current has dropped below the set value again, the output will
increase.
This means that the current sensors, along with the electronics, prevent
more power being supplied than the main fuses can tolerate.
Use at least 0.5 mm2 cable.

Installation
16. First start
When the CTC EcoZenith i250 is delivered, the heat pump is blocked to avoid it
being started unintentionally. EcoZenith I250 can be installed and started before
the bedrock/ground source or air/water heat pump is put into operation.
The EcoZenith i250 can also be started without a room sensor being fitted as
the curve which has been set then regulates the heating. Deselect the room
sensor in the Settings menu. The sensor can however always be fitted for the
alarm LED function.
Before first start
1. Check that the EcoZenith I250 and system are full of water and have been
bled.
(The EcoZenith i250 is bled through the safety valve on the top cover of the
product.)
2. Ensure that the brine system is filled with water and antifreeze and that it is
bled, or ensure that the compressor is blocked.
3. Check that all connections are tight.
4. Check that sensors and the radiator pump are connected to the power
source.
5. The backup heating thermostat has OFF as its factory setting. The recommended position is
= Antifreeze setting, around +7°C. The backup heating thermostat is reset on the electrical switchboard behind the front panel.
It is in the OFF position when it is turned anticlockwise as far as it will go (the
screwdriver slot should be vertical).
NB: On installation in a newly built dwelling, the regulations of the Swedish
National Board of Housing, Building and Planning (Boverket) must be
adhered to when setting maximum power output. The installer must key in
the four figure code 8818 under the menu: Service/Factory settings coded,
within one week – this locks maximum power. The maximum power output
must also be written on the rating plate with a marker.
NB: At the end of the installation, check the current transformers’
connection. In this situation it is important that you have switched off
any major consumers of electricity in the house. Also make sure that the
backup thermostat is turned off.

Installation
First start
Switch on the power using the safety switch. The display comes on.
CTC EcoZenith i250 now asks the following:
1. Select the language and press next.
2. Confirm that the system is filled with water and press OK. Press next.
3. Size of main fuse Choose between 10 and 35 A.
4. Specify the maximum electric heater power. Choose between 0.0 and
9.0 kW in different steps.
(This value does not lock the supply, but the value can be changed in
the settings menu.)
5. Select the option permitting the compressor (if the collector system is
ready or the air/water pump is already installed). When the compressor
is started for the first time, it is automatically checked that it is running in
the correct direction. An error message is displayed in the panel display
if it is rotating in the wrong direction. Switch any two phases to change
the direction of rotation. Use your hand to feel that the hot gas pipe
immediately becomes warm when the compressor starts, but bear in
mind that the pipe may be hot!

6. Specify the max. primary flow °C for radiator system 1.
7. Specify the inclination for radiator system 1.
8. Specify the adjustment for radiator system 2. If the primary flow sensor
for radiator system 2 is installed, repeat steps 7 to 9 for radiator system
2.
9. Current sensors identified. The CTC EcoZenith i250 then starts and the
start menu appears.
