Main optional accessories

In addition to the aforementioned standard features, including automatic bypass cooling, the equipment boasts a series of optional accessories that can significantly increase its already exceptional performance depending on climate and residence requirements.

Electrical preheating via an external 900 W battery

The electric heating coil prevents the formation of ice on the heat exchanger when exposed to low temperatures. The heating coil is installed in the air outlet duct and is connected to an HCC 2 controller that adjusts heat expulsion in order to ensure that ice does not form on the heat exchanger so that energy consumption remains as low as possible.

VOC (Volatile Organic Compound) sensor for demand controlled air quality

An HCC 2 unit can be equipped with a VOC air quality sensor. This sensor will constantly monitor the presence of naturally occurring and man-made gases in the air. Examples of vapours that can be detected:

Naturally occurring vapours, such as formaldehyde from building materials.
Chemical fumes from vaporizers, such as lacquers or perfumes.
Internal pollution, such as that generated by tobacco smoke or laser printers.
Emanations of fire-retardant substances in carpets, paint or furniture.

By using the VOC sensor in demand controlled ventilation, you can set the proper level of ventilation with the lowest possible electrical consumption. If a wireless remote control is connected, the VOC reading will appear on the screen as a three-level icon.

VOC (Volatile Organic Compound) sensor for demand controlled air quality

Hygrostat, Sauter HSC120 F001

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

CO² sensor

The CO² sensor is connected to the control accessory where controlling air changes depends on the CO² level of a given room.

Additional control options

HCV units feature an integrated control panel, demand-controlled operation and a humidity sensor built into the unit as standard. The HCC 2 residential ventilation unit is designed for hidden installation, so the basic unit does not have the integrated control panel.

Users can switch between manual mode, controlled by demand or weekly program via the control panel. Users can also select manual or automatic by-pass, they can activate the Chimney mode, check status of alarms and filters, etc. The following additional control options are available in addition to the built-in control panel:

Wireless remote control (HRC 3)

Wired control panel (HCP 10)

Benefits: Why a mechanical ventilation system?

Modern houses tend to be very airtight, so they must be ventilated daily. Otherwise, dust mites and mold could accumulate rapidly and deteriorate air quality. These residential ventilation units provide you with a demand controlled heat recovery ventilation system. This system supplies fresh and clean air to your home and it extracts stale air and unwanted moisture generated by the kitchen, laundry area and bathroom.

This ventilation equipment will help you create a comfortable and healthy indoor atmosphere and reduce your use of energy by recovering heat produced from the extraction of stale air, which is transferred to the fresh air supply. Orkli offers you ventilation solutions ideal for single-family homes, social housing and private apartment blocks, which can be installed in both renovation and new construction projects. A mechanical ventilation system extracts moisture from the air from wet rooms like the kitchen, bathrooms and toilets, and supplies fresh air to dry rooms including lounges, living rooms and bedrooms. Ventilation should be balanced, so that the amount of air coming in equals the amount extracted. In new construction and large remodeling projects, mechanical ventilation should be used with heat recovery, where heat from the extracted air is used to heat air introduced into a house.

A mechanical ventilation system is not an air conditioning system, but it can be used to reduce the interior temperature of the house through a bypass function, in which the cooler outdoor air enters the house to cool it follow prior filtering. This is particularly relevant in summer as well, when the outside temperature drops below the indoor temperature at night, the air enters the interior bypassing the heat exchanger and sending fresh air from the outside through a filter, then directly into the house. The automatic bypass function is activated when this occurs, exerting a cooling effect on all rooms. Energy demand is reduced in houses through use of heat recovery in winter and the "free cooling" bypass system in summer.
