Risk of water damage
• Never turn off the ventilation unit as this may cause condensation and subsequent leaks
from the duct system, with the risk of water damage.
Decide which of the three main operating modes you want your RCV 320 to run in and adjust
the settings as desired via Dantherm PC Tool, Dantherm Residential app or HRC3 remote con-
trol. Please note, however, that legislation may prescribe minimum levels of ventilation speed.
Check the fan speed manually. In manual operating mode, the ventilation unit will run at the
selected ventilation speed until this is changed manually.
Short press – activates manual operating mode. Each time the button
is pressed, the fan speed is increased by one level (level 0–4). After
level 4, the fan speed will start from level 0 again.
•
NOTE:
If the unit is running in manual operating mode - level 4 (fan boost)
or level 0 (off) it will automatically return to level 3 (nominal mode) after
four hours. The function of the auto setback can be customized via PC Tool.
•
The fan speed at level 0 can be locked via PC Tool. When level 0 is locked, the
fan speed will jump from level 4 to 1 as it increases.
Active manual operating mode is indicated by constant light in the correspond-
ing LED
When the week program is activated, the unit will automatically adjust the ventilation speed
according to a predefined week schedule.
You can activate the week program via the control panel on the unit, but you cannot choose
which week program you want to run. Selection between the 11 weekly programs (10 set
pr one adjustable in PC Tool) can only be done using the Dantherm app, the HRC3
remote control or a PC Tool.
Short press – activates the selected weekly program.
The active weekly program is indicated by a constant light in the corresponding
LED
Enable demand-controlled operation for automatic control of indoor air quality. This mode
uses readings from VOC, RH and/or CO
2
sensors to control the indoor air quality. It is therefore
necessary for the associated sensors to be connected during demand-controlled operation.
The CO
2
sensor can only be connected via an installed Accessory Controller (HAC).
Long press (five seconds) - activates demand-controlled operation.
Active demand-controlled operation is indicated by a slow flashing light in the
corresponding LED
