Components description
This section describes the individual components which are included in the HCC 260/360
unit. Please use the illustration on page 6 for reference.
Cabinet outer parts are made of aluzink sheet metal. The inner part is one moulded polysty-
rene 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
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.
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, where the heat is transferred to supply air.
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.
The unit´s main controller is named main PCB. It electrically connects all electrical and elec-
tronic parts and various accessory components.
Units are fitted with 4 temperature sensors that continuously monitor the temperature
changes on 4 sides of heat exchanger, i.e. in outdoor air, in supply air, in extract air and in
exhaust air.
The HCC 260 P1 unit, is not default fitted with a RH sensor. RH sensor is available as an acces-
sory.
HCC 360 P2 and E1 units are fitted with an RH sensor in the extract duct.
The humidity sensor will continuously monitor the quality of the extract air, and adjust the air
flow level accordingly. 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 fitted with two ISO Coarse class cassette filters. These filters protect the heat ex-
changer and improve the indoor climate by removing dust and particles in both airflows.
As alternative/accessory, an ePM1 class filter can be obtained. If ePM1 is used, then it is always
placed in the supply air, removing even smaller particles.
The unit is fitted with 2 pcs. spigot connections for draining condensed water. It is manda-
tory 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.
The unit is delivered with hanging rail.
