Antifrost Screen
The Antifrost screen is only displayed if a summer
bypass is fitted. In installations where a negative
pressure is not permitted such as where an open flue
fireplace or appliance is fitted, set this to bypass mode.
Standard available options are Airflow Mode (default)
and Bypass Mode.
An additional option is Anti Frost with Heater Mode
which should be selected if a pre heater is fitted. See
the next screen, below. (Currently unavailable option).
Airflow Mode - When the supply air temperature is
between 0° and -20°C, antifrost will automatically
activate. This will reduce the supply airflow rate and
increase the extract airflow rate to prevent frost forming
on the heat exchanger. During antifrost operation the
supply motor can stop for 15 minutes per hour and run
for 45, depending on the temperature below 0°C. If the
supply air temperature is -20°C or below the supply fan
switches off and the extract fan continues to run at
reduced rate to prevent frost forming on the heat
exchanger.
Bypass Mode - While the supply air temperature is
below 0°C, the antifrost mode will automatically
activate. This mode will open the bypass to prevent
frost forming on the heat exchanger.
