  • Dantherm home ventilation HCV 300-500-700 HCV 300-500-700

Balanced whole-house mechanical ventilation with heat recovery for private homes

The HCV 300-500-700 home ventilation units are packaged basic ventilation units complete with built-in control panel and demand-controlled operation.

A light-weight aluminium counter flow heat exchanger, developed and manufactured by Dantherm, offers efficiencies up to 95%.

The built-in control panel allows the user to adjust individual default settings. With the optional wireless remote control HRC 3 or the wired control HCP 10 the user gets access to further control options.

The duct connections can be electronically swapped from left hand side setup to right hand side setup. Thus the same unit can cover all installation demands, just at the touch of a button.

The HCV 300-500-700 has a built-in, automatically regulated by-pass module. On a hot day it leads the hot exhaust air past the heat exchanger to achieve the best possible cooling effect.

A wide range of accessories, internally as well as externally fitted, is available in order to cover any specific need for ventilation.

Features and Advantages
  • Alu heat exchanger with high efficiency heat recovery - up to 95%
  • Built-in by-pass module
  • Demand-controlled ventilation with integrated humidity sensor
  • EC fan motors with extremely low energy consumption (low SPI)
  • Time controlled ventilation level, based on 12 different pre-programmed week programs
  • Wired LAN interface that supplies data communication for smartphone app's as well as ModBus over TCP/IP. This is useful for connecting this unit range to external building management systems such as KNX
  • USB connection from which all settings and adjustments can be done safely with the corresponding Windows application, PC-Tool. 
  • Summer mode in which supply fan is stopped and any open window will supply cooler outside air, lowering the room temperature
  • Fireplace mode, creating a temporary inside overpressure to enhance chimney functionality

Wired Control HCP 10

Wired control HCP 10:

The optional prewired control unit is connected to the ventilation unit with a 6 m cable. 

The wired control HCP 10 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 (when RH and VOC sensors are connected)
  • Enable summer mode (only extract air)
  • Enable manual bypass 
  • Enable fireplace mode
  • Reading and resetting of alarms, including filter alarm

Wireless remote control HRC 3:

The wireless remote control HRC 3 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
  • Installer menu for adjustment and fault-finding

Circular electric duct heater for reheating of supply air:

The circular electric duct heater prevents ice building up in the heat exchanger at low temperatures. The electric heater is mounted in the supply air duct. The control current is connected to the accessory control HAC 2.

 electric heating coil

Built-in electric heating coil:

The electric heating coil protects the heat exchanger against icing up at low temperatures and ensures balanced ventilation down to approx. -15°C. The electric heating coil is mounted inside the cabinet and is connected directly on the unit. It is controlled by the embedded controller. No accessory control is needed.

Water heating coils:

The water heating coil kit includes 2RR, 2-way water valve, 0-10V servo motor, 230/24VAC trafo, duct sensor and tube sensor for frost protection. It is controlled by the accessory control HAC 2.




CO2 sensor:

The CO2 sensor is connected to the accessory control if the air change has to be controlled in accordance with the CO2 level in a given room.


Hygrostat, Sauter HSC 120 F001

The hygrostat is connected to the accessory control in case that a higher air change rate is required in rooms with high humidity.

VOC sensor  

VOC air quality demand sensor

The HCV 300-500-700 units 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.


Accessory control HAC 2 with 3 m cable:

One or more of the following functions can be connected to the accessory control:

  • After heating coils for water or electricity
  • Geothermal preheating/precooling coils
  • 24 VDC duct damper outlet
  • Stop function inlet
  • Fire/smoke detector inlet
  • External CO2 sensor for demand control
  • External hygrostat
  • Filter alarm outlet
  • General alarm

Power supply 230VAC – 24VDC, for duct control:

Power supply to be mounted in the accessory control if the ventilation unit controls a duct damper.

USB Cable  

USB cable, 3 m:

USB cable to be used in connection with software update of HCV 300-500-800 and Dantherm PC Tool (HPT 1).

 PC Tool  

Dantherm PC Tool Kit (HPT 1):

The PC Tool Kit contains a USB plug with program and quick guide + USB cable.

The Dantherm PC Tool has an installer menu, where the installer can adjust the HCV 300-500-700 unit, connect extra accessories, adjust various user settings, read and reset alarms, if any.

It also has a user menu, where the user can read and adjust various settings, such as week programs, set points, alarms and historical data about temperatures and air quality (accessory).
