Introduction
This section describes the individual components which are included in the HCC 2 unit. Please
use the illustration on page 6 for reference.
Cabinet Cabinet outer parts are made of aluzink coated sheet metal, finished with powder paint. The
inner part is one moulded polystyrene block. If adding accessory or exchanging parts, access
to all parts are available, just by removing the front cover and drip tray.
The cabinet is internal sound and heat insulated, with fire retardant polystyrene foam. The
unit´s cabinet is designed for mounting in 12°-40° C ambient temperature
Heat exchanger
The counter flow heat exchanger absorbs the heat energy from extract air and moves this
heat energy to the ingoing supply air, resulting in domestic ventilation with low heat loss.
Fans The supply fan supplies fresh outdoor air through the unit's heat exchanger to the ducts,
where it´s distributed to bedrooms, living rooms and possibly sauna or steam bath.
The extract air fan draws used, moistened and polluted air from house, through the unit
and heat exchanger, in which the heat is absorbed and moved to supply air. Finally the air is
exhausted to the outside.
Bypass damper
The motorized bypass damper overrides the heat exchanger functionality. This is used in
warm summer conditions, where colder outside air can be used for reducing inside tempera-
ture, when inside temperature exceeds an upper temperature limit.
Controller
The unit´s main controller is placed at the main PCB.
Humidity sensor While the HCC 2 ALU and E1 units are equipped with an RH sensor in the extract duct, the RH
sensor will be available as an accessory for the HCC 2 PLA variant. The humidity sensor will
(not included in
continuously monitor the quality of the extract air, and adjust the air flow level accordingly.
HCC 2 PLA)
This operation is named demand mode. If an HRC remote control is connected, the level will
be shown in the display using 3 level icon.
Using demand mode will result in the correct level of ventilation with lowest possible electri-
cal power consumption.
The unit is standard equipped with two G4 class cassette filter. These filters protects the
Filters
heat exchanger, and improves the inside environment by remove dust and particles, in both
airflows. F7 class filter can be purchased. If F7 is used, this is always placed in the supply air,
removing even smaller particles.
Water drainage
The unit are equipped with 2 pcs. spigot connections for draining condensed water. It is
mandatory to fit the spigot next to the T4 with a hose, discharging the condensed water to a
sever. Correct drainage is shown on the connection label placed on the unit. The remaining
un-used drain is to be blocked with the enclosed cap. 1 meter drain hose is delivered with the
unit.
Hanging rail
The unit is delivered with hanging rail.
