5 CTC V22/V40

For the property owner

Congratulations on buying your new product

You have chosen a CTC V22/V40 wood boiler, which we

hope you will be very pleased with.

CTC V22/V40 is available in two sizes. The lambda

model has automatic control of the air supply, the other

model has a manual air supply.

Both boilers have powerful suction fans which provide

good combustion with low emissions. The efﬁ ciency is

over 90%.

On the lambda model sweeping is easily performed with

a lever, so called lever sweeping.

The best system function is achieved by using a charge

group and mixing valve groups which control what

should be heated or which areas should be heated.

The boiler is designed to be burning to accumulators

and must therefore not be connected for burning directly

to a radiator system.

For the property owner

Your home's heating installation

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.

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.

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:

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

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.

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.

Outside Temperature

Adjustment

The curve can be parallel displaced (adjusted) by the

desired number of degrees to adapt to different systems/

houses.

An example

Inclination 60°C

Adjustment 0°C

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).

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.

CTC V22/V40

For the property owner

If the boiler is powered on, and the ﬁll door is open,

the fan operates at maximum speed.

2. Firing

2.1 Reverse burning

The combustion must last during a sufﬁciently long time, at sufﬁciently high

temperature and at sufﬁcient turbulence. This condition, time, temperature

and turbulence is often called the 3 Ts. A good mixture of these three

provides good combustion.

The ﬂue gas fan ensures that the ﬂame ﬁnds its way down the grate, and

with the help of a control ﬂue the ﬂame starts rotating. The fan sucks the

air and the ﬂame on through the ceramics where the remaining gases are

burned. The air continues through the heat transfer pipes and out through

the chimney.

CTC V22/V40

For the property owner

It is both inappropriate and prohibited to heat with waste, chip boards, painted

wood, pressure-impregnated wood or similar, as these materials emit gases

which are very corrosive and hazardous when heated

V40 factory setting:

Primary air setting: 7

Secondary air setting: 4

2.2 Fuel

• Moisture content, type, size and cut of the wood is of importance for

burning and for the operation of the boiler, among other things the

output.

• Suitable moisture content is about 15–25%. Higher moisture content

gives lower output and lower efﬁciency.

• The wood should be stored under roof or rain cover. The drier the

surrounding air is, the quicker the wood dries.

• The boiler is designed for 0.5 m wood and it is important that the wood

be cut. Large, round logs do not dry as well and are therefore less

suitable as fuel. Suitable piece size is when 3–6 logs can be placed next

to each other in the hearth.

2.3 Air setting

• CTC V22/V40 with Lambda probe automatically sets itself for best

burning with both primary and secondary air settings.

• For CTC V40 without Lambda probe the property owner sets the

primary and secondary air settings. The primary and secondary air

settings are set at the factory at an average value which corresponds

with most wood types and moisture contents.

With two dampers, the primary and secondary air can be set in intervals

between of 3 and 7 for desired combustion. Adjustment of the inlet air is

primarily done depending on the moisture content of the wood.

• The CTC V22 boiler supplies approximately 22 kW in ≈5 hours when

ﬁring with birch wood with 20% moisture content.

• The CTC V40 boiler supplies approximately 40 kW in ≈2.5 hours when

ﬁring with birch wood with 20% moisture content.

• Make sure that the ﬂue gas temperature in the chimney is not below

70ºC, 1 meter down, to avoid condensation.

For damp/roughly chopped wood:

Increase the primary air setting.

For dry/ﬁnely chopped wood:

Reduce the primary air setting.

The smoke should always have a transparent, light grey nuance.

CTC V22/V40

For the property owner

At delivery the ceramics are not completely dried out. This is done at the ﬁrst ﬁr-

ing. Therefore, during the ﬁrst two hours, ﬁre very carefully with small wood inlays

only.

Too much wood gets the boiler up to max. temperature and the fan stops. This

can provide undesirable emissions and possible cooling of the boiler with the

cooling coil cooling the boiler without the possibility of beneﬁting from this heat.

Appropriate quantity of wood means that, when the accumulator tanks are fully

charged, the wood in the boiler has all burned up. The warning High PT means

that there is too much wood.

It is important that, when loading the logs, you stack them as tightly as possible,

partly because you then get in more logs and can utilize the boiler maximally,

partly because you get more even and environmentally friendly combustion with

tightly stacked logs.

Plan the heating and wood inlay so that you utilise the boiler and the accumulator

system maximally.

2.4 Stoking

In order to get a good combustion, the moisture content of the wood is

important. There are two alternative ways to start combustion.

Alternative 1

1. Press the start button.

2. Open the door.

3. Fill with wood so that the bottom is covered with ﬁnely chopped wood.

Cover with newspaper. Make a small newspaper “fuse” with which to

light. Cover with another layer of ﬁnely chopped wood. Continue to ﬁll

on logs to a sufﬁcient quantity.

4. Light.

5. Close the door.

Alternative 2

1. Open the door.

2. Fill with starting wood/sticks and add newspaper. Continue to ﬁll with a

few logs.

3. Light.

4. Press the start button, close the door and wait a few minutes in order to

get an ember bed.

5. Open the door and ﬁll the boiler with wood to the suitable quantity.

6. Close the door.

CTC V22/V40

For the property owner

Do not open the ﬁll door when the boiler has reached its maximum temperature

or when the maximum ﬂue gas temperature has been reached, as there is a risk

of combustion of ﬂue gases in the hearth.

Any embers in the ashes could ignite. Always

store ashes in a safe manner

The ash door must

not be opened

during heating

2.5 Heating phase

• For CTC V22/V40 Lambda: after ﬁlling with the appropriate amount

of wood, the control system of the boiler monitors the heating fully

automatically.

• For CTC V40: The air is set before lighting. The ash door must not be

opened during heating.

2.6 Wood charging

Wood is charged as needed.

If the boiler is in the “Shutdown” phase and wood must be charged, start by

pressing the start button and the boiler will enter the “Stoking phase”.

If the ﬁll door is opened during ﬁring, smoke and ﬂare-ups may escape into

the room. Open the door a couple of centimetres and wait until the fan turns

quicker before opening the door completely.

2.7 Shutdown

When the wood has burned up, the output decreases and the ﬂue gas

temperature drops. When the ﬂue gas temperature drops to set value, the

fan and the charge group/charging pump stop.

2.8 Airborne noise

Airborne noise originate from the ﬂue gas fan. Normally the boiler room is

suited for heating products with a certain noise level. If the noise level is

disturbing noise damping material can be used in the boiler room to lower

the noise level. Do pay attention to distanses to the boiler and use non

burning material. If outdoor noise has to be reduced, use intended ﬂue gas

noise damper.
