Ventilation with heat
recovery to be mounted
within the ceiling void space
or on the wall

  • Ultra-thin home ventilation unit

The HCC 2 home ventilation system can be fully customized to match any apartment or house, newbuild or retrofit.

 

Fully customizable ventilation unit with heat recovery:
The HCC 2 is a unique and flexible home ventilation solution. With only 27,9 cm installation headroom it is ideal for installation in suspended ceilings or onto a wall, even hidden inside a closet. The unit can be electronically reversed, meaning that both air flows will be reversed. This allows the same unit type to be mounted with the inside/outside ducts connected to either the right or the left hand side of the unit. Electrical connections can be connected from either the left or the right.

PC-Tool:
Dantherm has developed an advanced PC-tool application for MS Windows computers. After installation of the unit, air ducts and condensate hose, the unit needs to be calibrated to the specific environment. Measurement of air volumes is done via built in air pressure ports, and appropriate initial adjustments are performed through the Dantherm PC-tool, connected to the HCC via a USB connection.

Wireless remote control:
Dantherm offers an LCD based wireless remote control, designed either to be mounted on the wall, or to be placed standing on a table or cabinet. This remote control is designed for the user, but also includes a special installer menu, where it is possible for the installer to do extensive settings without the use of the PC-tool.

Demand control:
The HCC 2 home ventilation unit can be fitted with RH and/or VOC demand-controlled automation that need not be touched once the system has been installed. The VOC sensor continuously monitors the level of artificial or natural organic chemicals of the extract air and adjusts the air flow level accordingly. Automatic demand control is based on a range of average consideration that guarantees a comfortable indoor climate in all conditions. By-pass damper and CO2 sensor are available as well.

Energy efficiency class A and A+
The standard version of HCC 2 is rated as energy efficiency class A. With an optional “A+ sensor kit” the HCC 2 will obtain energy efficiency class A+. Please refer to the tab “Accessories” to see which accessories are included in the “A+ sensor kit”.

Integration in Building Management Systems (BMS):
The HCC 2 home ventilation unit offers a data connection point over TCP/IP interface carrying ModBus protocol data. Upon request, Dantherm issues a protocol data sheet allowing a qualified BMS programmer to interface the HCC unit to any building management system, as well as KNX intelligent building system.

Features and Advantages
  • High efficiency heat recovery – up to 94%.
  • EC fan motors with low energy consumption (SFP data).
  • Energy efficiency class A in the standard version. With an optional “A+ sensor kit” the energy efficiency class A+ will be obtained. Please refer to the tab “Accessories”.
  • Only 300 mm installation headroom height is required.
  • Time controlled ventilation level, based on 11 different built in pre-programmed week programs. This reduces power consumption in periods with low ventilation demands.
  • Summer cooling mode, in which the supply fan is stopped, and any open window will supply colder outside air, decreasing the room temperature. This requires a wired control HCP 10*. 
  • Fireplace mode, creating a momentary inside overpressure, to enhance chimney functionality.
  • Easy-to-install and commissioning solution with built in air measure ports, for easy balancing with PC-Tool*.
  • Electronically left / right fan direction switching, allowing same unit type to adapt any physical installation requirements, regardless of ceiling and wall selection.
  • Demand controlled ventilation*.
  • Highly customizable unit, by adding a high variety of internal as well as external accessories. See more details under the tab “Accessories”.
  • TCP ModBus connection, for inter-operation with Building Management System.

Wired Control HCP 10

Wired control HCP 10

Dantherm offers a prewired control unit, which is connected to the ventilation unit with a 6 m cable. The wired control comes with a white plastic frame and a metal frame for fastening into a standard junction box. Alternatively Dantherm can supply a box for fixing to the wall in an appropriate place.

The HCP 10 wired control gives the user the following possibilities:

Manual control of air change (step 0-4)
Control of air change with week program
Demand controlled air change (if RH and VOC sensors are connected)
Enable summer mode (only extract air)
Enable manual bypass (requires an optional mechanical bypass to be mounted)
Enable fireplace mode
Reading and resetting of alarms, including filter alarm

Remote control

The remote control gives access to: 

Manual operation
Demand-controlled operation
Choice between 12 different week programs
Away operation when you are absent for a longer period
Night operation
Reading of outdoor temperature, supply and extract temperature, room temperature, relative humidity and CO2 level

Electrical Preheating Coil

External electrical preheating coil, 900 W

The electrical heating coil prevents ice building up in the heat exchanger at low temperatures. The heating coil is mounted in the outdoor air duct. The heating coil is connected to and controlled by the HCC 2 controller, which adjusts the heat output so as to ensure an ice-free heat exchanger with the lowest possible energy consumption.

 
Insulation Kit For Preheater

 

Pre-heat insulation kit

This insulation kit is designed for fixing to the HCC 2 preheater. This customized insulation kit protects against thermal bridges, condensation and excessive energy consumption.

Mechanic By Pass Module W Cable

 

Mechanic bypass module

The HCC 2 home ventilation unit can be fitted with an automatically controlled bypass damper module, that exploits the colder outdoor air to cool down the home, e.g. after a hot summer’s day, when the outdoor night time temperature falls below the temperature of the house. The bypass module leads all the hot exhaust air past the heat exchanger in order to achieve the best possible cooling effect.

RH sensor for energy class A+  

RH% demand sensor

The HCC 2 home ventilation unit can be fitted with a humidity sensor (RH%).
This sensor will continuously monitor the humidity of the extract air and adjust the air flow level accordingly. This operation is named demand mode. If a wireless remote control is connected, the level will be shown in the display using a 3 level icon.
Using demand mode will result in the correct level of ventilation with lowest possible electrical power consumption.
If both VOC and RH% sensors are fitted, the ventilation level is set by the highest demand from just any one of the sensors.

Included in the A+ sensor kit.

VOC sensor for energy class A+  

VOC air quality demand sensor

The HCC 2 unit can be fitted with a VOC air quality sensor. This sensor will continuously monitor the level of artificial as well as natural organic fumes in the air. Examples of included fumes:

Natural fumes, e.g. formaldehyde from building materials.
Chemical fumes from sprays, e.g. hair spray or perfumes.
Indoor pollution e.g. from smoking and printing with laser printer.
Fumes from fire retardant substances in carpets, paint and furniture.

Using the VOC sensor in demand mode will result in the correct level of ventilation with lowest possible electrical power consumption. If a wireless remote control is connected, the actual VOC level will be shown in the display using a 3 level icon.

Included in the A+ sensor kit.
