Overall ventilation functions
This section describes how the remote controller can be used to set various parameters and
display the units running condition .
The HCV units can ventilate your home via three different operation modes . These modes can
be selected according to your wishes . Keep in mind however that legislation may prescribe
minimum levels for air change .
Risk of water damage
• Never turn off the ventilation unit to save energy as this may cause condensation and
subsequent leaks from the duct system with the risk of water damage .
In manual operation mode the HCV 400 will run at the selected ventilation speed until this
is changed manually . This operating level can be selected via the control panel or the HRC3
remote controller and HCP10 .
When set to timer-controlled operation, HCV 400 will automatically adjust the ventilation
speed according to a predetermined weekly schedule . This can cover ventilation in a normal
family rhythm depending on whether one is home or out of the house . One of the 11 sched-
ules can be adapted with PC-Tool or remote controller .
Week mode is enabled via the control panel or HRC3 remote controller or HCP10 .
When set to demand controlled operation the unit is adjusted as needed . Using measure-
ments from the VOC and/or humidity sensor, the unit adjusts the fan speed according to the
need for air change . A VOC sensor measures the quality of the air .
This operating mode can only be selected if the unit is equipped with at least one of the sen-
sors above .
