DANFOSS HEATING
"away icon"
Main menu > Away
Use this command when you leave your house for a
prolonged period of time. The away command reduces
the ventilation rate of the system to an absolute mini-
mum, inside a defined interval. The unit will automati-
cally assume normal operation when the away period is
over. Note: if a heating surface is installed (optional) it
is turned off during away mode. If the heating surface
is used for heating the house, the room temperature is
reduced to 15 ˚C during away period.
"bypass icon"
Main menu > Bypass
The bypass function opens a passage parallel to the heat
exchanger, which stops the heat exchanging process.
When the bypass is open, outdoor air is led directly into
the house. The bypass can be activated in two ways:
1. Manually, by pressing the bypass command. This
will start the bypass function for 3 hours (the run
time can be changed in the settings menu). The
bypass will not activate if the outdoor temperature
is lower than +5˚C.
2 . Automatically, if the outdoor air is warmer than
16 ˚C (activation temperature can be changed in
settings menu). The bypass will automatically close
again, when the outdoor air temperature drops
below 15 ˚C.
Automatic activation of bypass is not possible in the
manual run mode.
