General information

Introduction

General information prior to installation

he following documents are supplied with the unit:

• Installation instructions/Software instructions

• User manual

• Wiring diagram

The instructions can be downloaded from the Nilan website: http://www.nilan.dk/da-dk/forside/ download

If you have further questions on unit installation after reading the instructions, contact your nearest

Nilan distributor, who can be found on www.nilan.dk/forhandlere.

The purpose of these instructions is to give the installer advice on correct installation and maintenance of the unit.

The unit must be started up immediately after installation and connection to the duct system. In periods where the ventilation system is not in operation, humid air from the rooms may penetrate into the ducts and form a condensate. The condensate may leak out of the valves and damage furniture and floors. In addition, condensate may form inside the unit, damaging the unit's electronics and fans.

The unit is supplied fully tested and ready for operation.

Unit type

Product description

ompact P GEO is a ventilation unit with an integral heat exchanger that also produces hot water for

domestic use as well as central heating via an ground source heat pump.

Compact P is designed for air flows of up to 275 m3/h at 100 Pa external counter-pressure. Compact P XL can handle air flows up to 430 m3/h at 100 Pa external counter-pressure.

The ventilation part draws the humid, vitiated air out of the dwelling via the bathroom, WC, kitchen and utility room and introduces fresh air into the habitable rooms, i.e. living room, bedrooms and office. The

could outdoor air is heated up in the heat exchanger (heat recovery) by the warm extract air.

In addition to a (counterflow) heat exchanger, Compact P has an integral heat pump. The heat pump uses the heat remaining in the extracted air following heat recovery in the heat exchanger to produce hot water. In case of high hot water consumption, there is a 1.5 kW electric supplement heater in the hot water tank, which can also be used to heat the water.

In the winter, the heat pump can be used to heat the supply air during periods in which not domestic hot water is being produced. The supply air can be heated up to 34 ºC.

As it is a reversible heat pump, it can be used in summer to cool the supply air. Compact P is able to cool

the supply air by up to 10 ºC. However, it will not function as an air conditioning unit, as it operates with a relatively low air change rate. Cooling of the supply air removes humidity from the indoor air, providing good comfort for persons in the dwelling, even if the indoor temperature is high. Compact P is able both to provide cooling and produce domestic hot water, so it could be said that the cooling of the supply air is "free of charge".

The energy-efficient and low-noise GEO ground source heat pump heats the home via floor heating or l

ow-temperature radiators. It extracts energy form the ground. The heat pump has an electrical power supply to help it to function during very cold periods. The GEO can cool the dwelling during the summer by passive cooling, using either the floor heating system or fan coils.

The GEO ground source heat pump can also be used to help produce hot water for domestic use, either by pre-heating the water in a buffer tank, or directly in a Compact P hot water tank, if bought with a solar coil.

Accessories

lectrical preheating element for frost protection

In longer periods of sub-zero temperatures, the high-efficiency counterflow heat e

xchanger will ice up. To avoid icing, it is recommended that an electrical

preheating element is mounted.

The preheating element uses very little energy, but ensures efficient heat recovery without de-icing, thus achieving an overall saving in energy consumption.

Adjustable water comfort heater

A water comfort heater can be used to increase supply air temperature to the d

esired level. It is fitted in the supply air duct and must be connected to the

primary heat supply.

Supplied with a two-way regulating valve, temperature sensor and frost thermostat.

Electric heating element

An electric heating element allows the supply air temperature to be raised to the d

esired level. Electric heating elements are supplied for mounting in the supply

air duct, and are provided with the necessary sensors.

Pollen filter F7

The unit is supplied as standard with a G4 filter.

f persons in the dwelling suffer from a pollen allergy, there is an option for mounting a F7 pollen filter in the outdoor air inlet to minimise the pollen in the indoor air.

EM box

With an EM box it is possible to divide the extract air between the kitchen and b

athroom.

If the cooker hood is operating via the unit and is switched on, air extraction from the bathroom reduces slightly to allow sufficient air for the cooker hood to extract kitchen fumes.

The EM box has a metal filter which efficiently separates grease particles from the cooker hood air, thus protecting the unit.

CO2

sensor

Fitting a CO2

sensor means the ventilation speed can be pre-programmed to run

higher ventilation levels in the event of high CO2 level in the extracted air. CO

levels can be programmed.

Safety group

The safety group, which is made of brass, consists of a stop valve with an integral n

on-return valve, a safety valve and drain cock. It can be installed directly

beneath the hot water tank.

Safety features

During periods with cooling ventilation, hot water in the tank can reach very high t

emperatures - up to 80 ºC.

A maximum temperature of up to 60 ºC can be set in the control system to prevent scalding, but active cooling is then limited.

To make full use of the cooling function, scalding protection should be fitted that mixes hot water with cold to bring the temperature down.

If a solar panel is used to supplement hot water heating, scalding protection must be fitted.

Flexible silencing

To facilitate later servicing of the unit, we recommend fitting a flexible connection between the unit and the duct system.

Nilan's sound damping flexi-hose gives good sound damping both to the duct system and to roof stacks.

Trolley

A trolley makes it possible to lift the unit of the pallet without physical strain. T

he same trolley can be moved to wheel the unit around.

SHW hot water tank

If there is a large demand for hot water, a 250 litre hot water tank can be c

onnected. The hot water tank is heated by the central heating system’s heat pump and/or via solar panels. The water runs from the SHW tank, through the DHW tank in Compact P, before running into the domestic hot water supply.

Installation

Installing the unit

Transport into the dwelling

ompact P is supplied in one piece on a pallet, packed in cardboard.

It is fitted at the factory with 4 lifting straps, one for each top corner. This makes it possible to lift in the unit with a crane. When lifting the units with the supplied straps, these must be at an angle of max. 45° from the vertical.

Nilan also offers a lifting trolley, with which the unit can be lifted directly off the pallet and into the building. If the filter box is removed, the unit can be manoeuvred through an ordinary door.

Positioning of unit

ATTENTION

hen setting up the unit, consideration must always be given to future servicing and

maintenance.

It must be easy to replace filters, and it must be possible to perform tasks such as removing the heat exchanger, replacing fans and other components.

ATTENTION

minimum free space in front of the unit of 60 cm is recommended.

It is important that the unit is level in order to achieve proper run-off from the condensate tray.

The unit should be positioned on a level and vibration-free substrate. In itself, the unit is low-noise and

ow-vibration, but even so, account must be taken of possible vibrations which could be transferred to building parts. We recommend maintaining a minimum 10 mm gap from building parts and other fixed equipment.

ATTENTION

or noise reasons, it is recommended that the unit is positioned with its rear panel against an

outer wall.

At the lower rear and sides there are punched areas which can be clipped out. This avoids the necessity of cutting holes yourself.

The rear angle iron on the base frame can be removed, allowing the unit to be pushed up against the wall, thereby concealing the water connections.

ATTENTION

f a screen is mounted over the Compact P, it must be easy to dismantle this.

Ground collector circuit

xamples of the laying

By laying the geothermal circuit there are some range distances, which need to be observed to get a unit which will have an effective and smooth operation. Further local authorities may make requirements for installation and acceptance of the facility before entry into use.

In some cases where there is less space vertically holes is drilled for hoses, but most lay the hoses horizontally. Below are some examples of laying the ground collectors.

ATTENTION

s is important to pressure test the pipes for tightness one by one immediately before covering

with soil, as during handling.

CO2

sensor

It is possible to purchase a CO2 sensor as an accessory if it is wished to control the ventilation level via the CO2level in the dwelling.

The CO2 sensor is positioned in the extract air from the dwelling, and mounted on the beam with the screws supplied:

The wire from the CO2sensor is led to the circuit board and connected as shown below:

The three wires are connected as follows:

ND: Blue Out: Black 24V Brown

Cooker hood and EM box

here are several benefits from connecting the cooker hood to the dwelling's ventilation system.

Firstly, there is full heat recovery of heat from cooking.

Secondly, the unit is able to provide balance in the ventilation. If the cooker hood does not run via the ventilation system and if the house is new and airtight, use of the cooker hood will create a underpressure in the dwelling, minimising the suction effect from the cooker hood and also creating smoke problems, for instance if a wood-burning stove or open fire is installed and in use. By running the cooker hood via the ventilation system, the unit can increase the supply air as the volume of extract air from cooker hood operation goes up. In this way, a balance can be maintained in the dwelling, and the

cooker hood will retain its full suction power.

In the case of ventilation of a large dwelling/building, with more than one bathroom, there may be

problems creating sufficient air capacity for the cooker hood. In these cases, an EM box will be an ideal

addition, as it minimises the extract air from the other high-humidity rooms for the short period that

the cooker hood is in use, and in this way ensures sufficient air for extraction via the cooker hood.

ATTENTION

f the cooker hood is connected to the ventilation system, it is important that it is fitted with a

good grease filter and that this can be regularly cleaned.

User selection 1

User selection 2

EM box

The potential free contact for the cooker hood is connected to User selection 1 or 2, which are

rogrammed in the unit's software under the section General settings. User selection 2 is chosen if an

EM box is to be installed.

Other electrical connections

ser selection 1

It is possible to override the unit's functions via an external signal from a potential free contact.

The User selection function can be used for many purposes, e.g. in the case of a wood burning stove or open fire. Initial settings of the ventilation system set up a small underpressure, so that humidity in the air is not forced into building parts. This is naturally a disadvantage when lighting a wood burning stove, as smoke will enter the room. By means of an potential free contact, one of the fan speeds, e.g. fan speed 4, can be set to run with a slight overpressure instead, so the smoke goes up the chimney as it

should.

Connection to CTS700 control system:

Potential free contact

User selection 1 is programmed in the unit's software under General settings. See the options in the

oftware instructions.

User selection 2

s with User selection 1, it is also possible with User selection 2 to override the unit's functions via an external signal from a potential free contact. The difference is that by activating User selection 2, the control system also transmits an output signal.

User selection 2 has the higher priority and is therefore used for cooker hood operation if a cooker hood is connected to the ventilation system. Normally fan speeds 3 or 4 are set for cooker hood operation. The output signal can be used for connecting an EM box or external damper which is to

assume a particular setting during cooker hood operation.

There are many other uses for User selection 2 which we shall not discuss further in these instructions.

External room temperature sensor

o you not want to control the unit according to a room temperature measured through the T3 extract

air, an external room temperature sensor can be connected..

The room temperature sensor is placed in the room, which should be the reference for the house.

Fire protection

fire thermostat or external fire automatic can be connected. It must be a joined signal, when it is

broken the Compact P register it as a fire and stop the unit.

Note! If the unit is connected to external fire automatic, you set the software: General Settings/

ervice/Auto reset for external fire alarm to "On".

Common alarm

f the unit is located in a place where access is poor or infrequent, and if the control panel is also located

here, it may be hard to observe any alarms.

An external alarm in the form of a light or acoustic signal, etc., can be connected to the unit.

External heat supply

ompact P is able to control an external room heating such as electric radiators or a floor heating

system.

The room temperature is monitored by the Compact P, which block the external heating supply when

there is no need for heating. If Compact P cannot achieve the desired room temperature through the ventilation, the external heating supply is released until the room temperature is in the desired level.

The external heat supply is connected via relay 8, and set in the touch-display under the menu: Ventilation-/Temperature regulation

A maximum effect of 500W can be connected (Compact P Polar need to have a transfer relay mounted).

Connecting EHD damper

o conduct outdoor air down through a geothermal pipe in the ground makes good sense. The air is

heated during the winter and cooled in the summer by the ground.

But passing outdoor air through such a geothermal system may not be the best idea in the spring and

autumn, but taking it directly through a roof vent is recommended.

The CTS700 control system has a built-in function that measures whether the geothermal pipe or roof vent provides the best option for air intake.

It measures the outdoor temperature during a stabilising period from the geothermal pipe and roof vent respectively. The measurement indicates where it is best to direct the outdoor air. CTS700 sets the EHD damper to the best option, and continues ventilation for a set period, referred to in the program as holding time.

The EHD damper is connected via relay 7 and set on the display menu item: Ventilation / Frost protection or de-icing / Frost protection.

Passive cooling function

EO has a passive cooling function. It works by the soil which cools the temperature of the brine, the

cold brine water used to cool the water in the central heating floor system or led to a fan coil.

Passive cooling by the floor heating system

An external temperature sensor is connected to digital input 10. When the contact is switched on GEO goes into passive cooling, where the circulation pump for the brine circuit and the circulation pump for the central heating are running. The relay output 10 is activated and turns a tree-way-valve, so the brine water is led to the passive heat exchanger (not a Nilan delivery). When the contact is switched off

again, GEO will go back to normal operation.

The external temperature sensor is often equipped with an infrared sensor, which measures the floor temperature and stop the cooling before, dew is formed on the floor.

Condensate drain

Important information

ompact P is supplied with a reinforced 20 mm condensation drain pipe with built-in water lock.

ATTENTION

nstall the condensation drain with an even slope of minimum 1 cm per metre to the nearest drain. The overflow from the safety valve to the cold water supply must be piped to a visible drain.

ATTENTION

f the unit is placed outside the building, the condensation drain must be protected against icing up. The fitter is responsible for ensuring that the unit is protected from freezing.

The connection of the water lock must be airtight to prevent air being sucked into the unit, trapping c

ondensation in the unit. Ehen the condensation overflows the tray and runs out of the unit, damages

must be expected.

After fitting the water trap, you must test the function in the following way: Fill the condensate tray with water. Start up the unit at highest fans speed, and allow it to run for several minutes. After that control that no water is left in the condensation tray (the unit must be connected to the duct system, and the lid must be on during the test).

The water trap can dry out, preventing water to run out from the unit condensation tray. Control the

water trap in regular intervals, especially after the summer and top up with water if needed.

The water trap is integrated in the pipe running from the condensation tray to the drain.

and provisions.

Nilan's hot water tanks are double-enamelled, ensuring long life. The efficient foam insulation protects a

gainst unnecessary heat loss.

All connection nozzles for water have 3/4" thread and are located in the tank bottom.

The tank is also fitted with an electronically-monitored sacrificial anode that automatically displays a warning on the display when it needs changing.

Compact P / Compact P Polar - GEO (English)

BY NILAN

CAUTION

hanging the anode when notified on the display is important. Failure to do so can cancel the

guarantee on the hot water tank.

The tank is fitted with a 1.5 kW supplementary electrical heater deactivated by default and activated v

ia the control panel if required.

ATTENTION

he supplementary heating must not be activated before the water tank is full of water.

Hot water circulation

f wished, hot water circulation can be established by fitting a non-return valve and a circulation pump

for domestic water to the tank's circulation connector (1).

If hot water circulation is not established, the connector must remain closed with the factory-mounted shut-off plug.

ATTENTION

ot water circulation can lead to a significant heat loss in the pipes, diverting a good proportion of the heat pump's output. To avoid this, circulation pipes and the hot water loop must be insulated with at least 30 mm mineral wool.

It is advisable to set a timer so that the circulation pump is not running constantly.

Solar coil

ll Compact P SOL models have integral supplementary coil, see connections list.

The solar coil with a surface area of 0.6 m2 is intended for solar heating systems, though it can also be connected to other heat sources.

ATTENTION

f a solar collector or other heat source is connected to a Compact P model, it is recommended

that a safety group is connected to the hot water outlet to secure against scalding.

Softened water

f it is wished to soften water with salt in a Nilan hot water tank, the following must be observed:

• The hardness of the water must be at least -2° dh (proportion of alkaline earths 0,4 mmol/l)

• The conductivity must be between 13 mS/m og 150 mS/m (millisiemens per m)

• The pH value must be between 6.5 and 9.5

• The chlorine content must be under 250 mg Cl/l

If the above criteria are exceeded, the anode current will be too high, the anode will break down too

quickly and the water will begin to smell bad.

CAUTION

emineralised water (double ion exchange) must not be used as the tank will corrode very rapidly. Demineralised water is also called totally desalinated water and deionised water.

Brine circuit

fter completed and demonstrated leak testing, brine can be filled. Filling the brine should be

performed by a qualified installer.

It is recommended to buy ready-mixed brine with corrosion inhibitors. If you mix the brine by yourself,

the water quality must be suitable for brine.

CAUTION

nsure that the brine hoses are deflated and without dirt, befor the brine is connected to the

heat pump.

Isolation of the brine tubes

ll pipes to and from the ground collectors / geothermal circuit must be isolated completely into the

heat pump, to prevent condensation on the cold tubes.

A collection tray must be established for condensation water from the heat pump and water from the safety valve.

Safety for the brine system

The brine hoses is equipped with a pressure control which make an alarm by falling pressure in the ground hoses. The alarm is triggered, if the pressure falls below 0,6 bar. The unit is turned of and cannot start up again automatically.

The ground hose system must be designed as a closed system with a pressure at rest of 1,5 - 2,5 bar.

CAUTION

safety device must be connected to the hot water tank.

When water is heated to 60 °C, it expands by 2%. A pressure tank could burst without a safety valve k

eeping excess water out. The safety valve should therefore drip during warming up.

Installation:

The following should be remembered during installation: a

. The double nut is attached to the water heater’s cold water pipe so that the arrows are pointing in towards the water heater (in the direction of the flow). The joint with the water heater is sealed using a threaded washer. b. The joint between the double nut and the system is sealed using fibre packing. c. The rubber ring seal (the O-ring) is fitted to the unit so that it can function as a seal between the safety valve and the unit in such a way that the valve is locked.

The end of the overflow pipe must be visible, and it must be able to run out safely via the drain.

ATTENTION

s water expands as it heats up, the safety valve will drip.

ATTENTION

It is up to the installation engineer to tell the customer where the safety valve is and how it works, and also that it must be regularly checked at least twice a year in order to prevent incrustation.

Safety group with anti-scald protection

he control system contains as standard a temperature limit for domestic hot water of 65 ºC. This

setting prevents users from scalding themselves when the hot tap is turned on.

It also means that when Compact P is in cooling mode, cooling will stop when the domestic hot water reaches a temperature of 65 ºC.

If the cooling requirement is higher than this, the temperature limit may be raised to 80 ºC, but in this case an anti-scald device must be mounted under the hot water tank, to prevent users from scalding themselves when turning on the hot tap.

The anti-scald device mixes hot water with cold water, thus bringing down the temperature and avoiding scalding. This will extend the period for which Compact P can perform cooling.

Ventilation mounting

Duct system

Legislation

ATTENTION

ll work must be carried out by qualified personnel and in accordance with applicable legislation

and regulations.

Ducts

here are two systems for transporting air round the building.

Spiral tubes

Spiral tubes are metal ducts which are cut to size with an angle grinder, screwed together with bends and manifolds and laid out in accordance with the working drawing. The duct pipes are typically laid at

the rafter ends and fixed with perforated band or suspended with suspension band. Avoid unnecessary bends in the ducting.

To avoid noise transmission, where sound is transmitted from room to room, a sound damper must be mounted in each room.

The ducts must be insulated to avoid heat loss and condensation. In some cases this can be avoided if the ducts are led through the ordinary insulation or inside the climate screen.

NilAIR tubes

NilAIR tubes are a flexible system which is easy to mount. The tubes are easily cut to size with a hobby knife and laid according to the working drawing without use of bends and manifolds. A manifold box is installed after the unit and the tubes run from this out to the various rooms.

With NilAIR tubes it is unnecessary to mount sound dampers in each room, as there is no risk of noise

transmission.

If the tubes are led outside the climate screen they must be insulated to avoid heat loss and condensation. This is easier than with spiral tubing, as NilAIR tubes are easier to lead through ordinary insulation.

NilAIR tubes are more flexible than spiral tubing and can therefore be laid in places where ordinary spiral tubing would be impossible.

Unit

Nilan recommends mounting a flexible connection between the unit and the duct system.

This is to avoid oscillations from the unit being transmitted to the duct system, but also to ease future

servicing where it is necessary to move the unit.

Nilan offers flexible silicing, which, apart from providing a flexible connection between the unit and the

duct system, also dampen the passage of sound from the unit to the duct system.

Flexible silencing are insulated for condensation, but it may be necessary to insulate them further to

meet local requirements for duct system insulation.

Extract air

xhaust valves are mounted in the moisture-generating rooms and strategically placed where they can

extract the moisture air most effectively.

Moisture-generating rooms:

• Bathroom

• Toilet

• Kitchen

• Utility room

Supply air

Supply air valves are mounted in habitable rooms and strategically positioned to give the minimum annoyance. For example, it is not recommended to mount incoming air valves over areas where people sit, as the air in some cases can be perceived as a draught.

Habitable rooms:

• Living room

• Kitchen-living room

• Bedroom

• Office

Roof stack

The roof inlet and outlet must be positioned and designed to limit pressure fluctuations in the

ventilation system caused by wind impact, and also to prevent access by birds and other animals, and

to ensure that the inlet and closed duct system are kept free of plant parts and foreign objects.

The air inlet must be located to minimise the risk of short-circuiting from the discharge air, having

regard to the prevailing wind direction.

The air inlet should be placed a minimum of 0.5 m above the roof surface, but a minimum of 1 m over flat black roofs up to the underside of the inlet, to ensure that warm air is not drawn into the building in the summer. The air inlet should be located on the north or east sides of pitched roofs.

Sound damping should also be mounted between the unit and roof stacks to avoid noise annoyance to

neighbours.

Initial regulation

mportant information

ATTENTION

or the ventilation system to operate optimally, it is important that initial regulation is carried

out correctly. We recommend having this done by experts.

It is important to measure the total supply (inlet) air and extract (outlet) air. The system must have a minimum vacuum, i.e. it must draw in more air out than in, to avoid humidity being pressed into the building construction.

Initial regulation connectors

he unit has initial regulation connectors for measuring the supply air (inlet air) and extract air (outlet

air) volumes.

The graph can be used for roughly setting the main air volume for dry operation without condensation precipitation, and with approximately the same temperature for outdoor air and extract air.

On the extract air side (outlet air), the pressure drop dP4-3 [Pa] is measured between the connectors labelled 3 and 4. The air volume qv [m3/h] is read off on the graph.

On the supply air side (inlet air), the pressure drop dP2-1 [Pa] is measured between the connectors labelled 1 and 2. The air volume qv [m3/h] is read off on the graph.

ATTENTION

he capacity in the pressure drop diagram is based on a dry heat exchanger.

Pressure fall diagram

The measuring connectors are inside behind the t

op front panel.

Start-up

Central heating

Filling with water

ATTENTION

efore starting the heat pump and the circulation pump, the central heating circuit must be

filled with water

Fill central heating circuit with water via the feed tap until the correct water pressure is obtained. It is

mportant that all circuits in the central heating system are open during filling.

ATTENTION

rdinary water or all common types of antifreeze can be used

There is an automatic vent fitted, which is activated wen filling with water. Check that the cover on the

vent is loose.

Once the central heating circuit has been filled to the correct water pressure, the circulation and heat

pump can be started.

Topping up water

The water pressure must be carefully checked the first few days, even several times a day. It may be necessary to top up the water in the central heating circuit if the water pressure has dropped.

ATTENTION

t is important that the circulation and heating pump is switched off while topping up the water

The water pressure will stabilise after a few days, after which the checks can be reduced to once a

month.

ATTENTION

f the central heating circuit requires topping up after the start-up phase, it should be checked

for leaks

Check the particle filter

here may be some particulate matter in the central heating circuit, and the heating pump must be

checked immediately after being put into operation.

The filter must be checked several times a day just after installation until it stays clean. With normal

operation, it is enough to check the filter twice a year.

Cleaning the particle filter:

1. Switch off the heating pump on the control panel (Settings: Central heating / Standby functions / Turn off central heating)

2. Turn the shut-off valve to close off the circulation

3. Remove the filter and rinse until clean

4. Replace the filter

5. Turn the shut-off valve to open up the circulation

6. Switch the heating pump back on
