Frost Protection
Frost Protection is required to prevent condensate
freezing in the heat exchanger at low temperatures.
The process is fully automatic. The method used for
frost protection will depend on the model and
building it is installed in.
For buildings with a leak rate of 3m
3
/hr or less (at
50Pa), a balanced frost protection mode must be
used. A balanced mode must also be used when a
combustion device without a dedicated air supply is
present.
Airflow (Imbalanced)
Airflow mode reduces the Intake flow and increases
the Extract flow in varying proportions dependent
on the incoming air temperature. The unit will
continue to recover heat as low as -20 °C. At this
point, the unit switches to ‚Extract Only‘ mode.
Bypass (Balanced)
Bypass mode opens the Summer Bypass and stops
recovering heat until the external temperature
increases sufficiently.
Relays
Select whether the external preheater outputs are
activated. These outputs are 230V 5A maximum
each.
