Introduction

Overview

Introduction

This is a user guide for the home ventilation units HCV 4/ HCV 5 from Dantherm A/S.

The table of contents below provides an overview of the sections contained in the man-

ual.

Serial number

For future inquiries concerning e.g. spare parts, please note the exact serial number of

the unit here: ______________________

This guide covers units with serial numbers that are equal to or higher than:

1201091250905

Warning

The power supply must not be connected before the duct system is mounted.

The valve unit must not be used to dry out newly constructed houses, either during or

immediately after construction.

The ducts must be sealed, and the unit must not be conne

cted to them until the house

is move

-in ready, that is, clean and dried out. This is to prevent building dust and con-

densed water from accumulating in the duct system and ventilation unit, which may

present a risk of hygiene problems later on.

A failure t

o comply with these requirements will result in the cancellation of the guaran-

tee on the unit, and any subsequent type of required service will be carried out at the

customer's expense.

Important

Follow the specifications in the installation guide before using the unit!

Product description

Introduction

This section provides a description of the unit.

Use of the HCV

The HCV unit is used to ventilate private homes.

The unit supplies fresh, heated outside air through the unit to the home.

Contaminated and hot exhaust air is used to heat the outside air through heat recovery.

Function description

Important

The ventilation system must always be running!

With the exception of the four hours during which the unit can be stopped from the

control panel, stopping the unit is not recommended. Stopping the unit for longer peri-

ods of time may

result in the condensation of fresh air in the pipe installations and ven-

tilation unit, which carries a risk of water damage

in the building's construction, damage

to the unit, and hygiene problems.

Stopping the ventilation, even for l

onger holiday periods, is therefore not recom-

mended. If necessary, turn the unit down to fan step 2 or 1 in manual operation instead.

Function

The unit blows fresh outside air into the house.

Contaminated and humid air is sucked out of th

e kitchen, living room, bathrooms, etc.,

and then led through the unit, which uses the heat from the old air to heat the fresh

outside air, before the latter is blown into the house.

Control panel

The control panel is used to set the unit's functions.

The control panel is described in greater detail on page

Automatic demand

control

When the unit is running in automatic demand control mode, the volume of air used is

regulated depending on how humid the air inside the house is. This is measured by a

humidity sensor, which is located

in the ventilation unit's exhaust duct.

•At a humidity level higher than 45% RH, the unit will run continuously at fan step 3.

•At a humidity level lower than 45% RH, the unit will make a slow downward adjust-

ment. If the humidity is very low over a longer period of time, the unit will

finally run

at fan step 1.

The set point for the automatic demand control can be adjusted using the wireless re-

mote control.

Automatic demand control is always recommended because it ensures the air change is

carried out as needed, while preventing the hou

se from becoming excessively dry for

inhabitants, particularly during winter months.

Function description, continued

Manual operation

If a different volume of air is desired than what the unit provides automatically through

its automatic demand control, the user can manually select from fan steps 0

-4. See the

following examples:

Step

Function

On the control panel the unit can be set to four different speeds,

fan step 1-4.

The unit is shut off. Should only be used in the event of unpleas-

ant outside odours.

If the fans are shut off for more than four hours, a risk of con-

densation arises in the ducts and unit, which may result in mois-

ture damage.

(all four lights for the fan step are off).

Note that fan step 0 will only remain active for a period of 4

hours, after which the unit will return to fan step 3.

Can be used overnight or while away from home, (e.g. while away

on holiday).

When the house is empty, the ventilation can be temporarily re-

duced.

Used for normal ventilation needs.

Can also be used while away from home, if fan step 1 does not

provide sufficient air change

Normally used for greater ventilation needs

For example: for cooking, bath, drying large quantities of

clothes, guests and excess heat

Used as needed for greater levels of air change, such as during

and directly after a party, when the house requires ventilation.

Note that fan step 4 is only active for four hours, after which the

unit will again run at fan step 3.

Function description, continued

Manual bypass

The purpose of the bypass function is to cool the home by allowing cool outside air

directly into the home without heat recovery.

During normal operation (when manual bypass is

not

activated), the unit cools by

using the automatic bypass control when outdoor and indoor temperatures allow,

which is why, in most cases,

manual

bypass is not necessary.

For homes with large, south

-facing glass facades that tend to generate more heat,

it may be necessary to activate the manual bypass early in the spring and fall, when

the automatic bypass function will not otherwise activate a cool

-down with outside

air because the outdoor temperature is below 15°C.

In manual bypass, the unit delivers cool

outdoor air to the home for six hours. In-

formation on set points for manual and automatic bypass is available in the instal-

lation guide.

*) Can only be used in HCV 5

Filters

The purpose of the filters is to remove dust and other contaminants before they are

blown into the house, and to protect the heat exchanger and fans from the accu-

mulation of dust and dirt that come from the home.

The unit is delivered as standard with G4 filters for both supply and exhaust air. An

F7 pollen filter (optional extra) can be connected for the supply air, which is an

even finer filter, for example for individuals who suffer from pollen allergies

. The

filters must be changed regularly; read

more about filter replacement in the “Preven-

tive maintenance” section on page12.
