Operation (user)
Overall ventilation functions
Never switch off the main power to shut down the ventilation. This could ultimately result in
condensate water dripping from air inlets.
The HCC2 unit is able to operate in the ventilation and override modes mentioned in this
section. Please be aware, that the different operation modes cannot be activated via the unit
itself, but have to be activated via an additional remote control (HCP 10/11 or HRC3) or via the
Dantherm Smartphone app.
The units can ventilate your home in three different main operation modes. The modes are
selectable according personal needs, taking in mind that national rules and regulations, can
state a minimum ventilation requirement. Auto mode requires an accessory sensor
Mode Description
Manual In manual operation, the unit will run in the required fan speed at all times.
Fan speed 4 is 130% boost mode. De-activates automatically after 4 hours
Fan speed 3 is nominal fan speed, defined as 100%
Fan speed 2 is 49% of speed 3
Fan speed 1 is 49% of speed 2
Fan speed 0 is fan stop. De-activates automatically after 4 hours.
Week timer Timer controlled operation mode sets the fan speed according a week time
table. The controller has 10 fixed and 1 custom timer. Select a fixed time
table that cover your requirements or create a custom timer, in the PC Tool.

Demand
(RH or VOC
sensor needed)
In auto mode (demand), the unit will automatically adjust the ventilation
level, to comply with the ventilation needs, measured in the outgoing air
by VOC and/or RH% sensors. This operation mode is only possible if the
unit is fitted with VOC and/or RH% sensor.
On top of the above main ventilation modes, the user can select some override modes for
various purposes. These overrides will disable automatically depending on time or tempera-
ture.
Overrides Description
Fan boost 130% boost in 4 hours.
Summer mode Supply fan off, extract fan still running, and colder air will flow through any
open window. This reduces inside temperature in summer times, with half
energy consumption.
Bypass
(accessory, if
not standard
equipment)
Both fans running, but no heat recovery. This will automatically supply
colder outside air, that reduces inside temperature in summer times.
Fireplace
booster
7 min. with extract fan reduced to 50% This creates an overpressure en-
hancing the chimney function, when lighting a fireplace
Night mode Sets the fan to speed 1 at night regardless of any other mode. Start and end
time can be set from the remote control
Away mode Sets the fan 2/3 of the time to speed 1 and 1/3 of the time at speed 0. Disa-
bles automatically after 28 days
