Main operating modes
Risk of water damage
• The ventilation system must always be operating!
• Besides the four hours where the unit can be stopped by the control panel, it is not advis-
able to stop the unit. This may cause condensation and subsequent leaks from the duct
system and in the ventilation unit with the risk of water damage in the building construc-
tion, damages on the unit and sanitary problems.
• Hence it is not advisable to stop ventilation – also during longer holidays. If necessary,
turn the unit to Fan Step 2 or 1 in Manual Operation instead.
The unit supplies fresh outside air into the house.
Polluted and moist air is evacuated out of kitchen, living room, bathroom etc. and led
through the unit. The heat exchanger uses this air to heat up new, fresh air, before the fresh
air is supplied into the house.
Decide which of the three main operating modes you want your HCH5 MKII to run in and ad-
just the settings as desired via Dantherm PC Tool, Dantherm Residential app or HRC3 remote
control. 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 text for which program is selected/set by default.
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 every 5 sec.
