Frost alert
As soon as the outdoor sensor measures a
temperature between -1 °C and +3 °C (+30 °F
to +37 °F), the frost alarm symbol flashes on the
display.
Pay attention to the following:
‚ Even if the frost alarm does not flash, there is always a
risk of frost or icing at temperatures around freezing
point. An outdoor sensor can only measure the local
temperature at the installation site.
‚ The flashing cannot be switched off. It stops auto-
matically as soon as the temperature is outside the
specified range.
‚ If you have connected several outdoor sensors to the
base station: By default, the channel with the small-
est channel number is always used for the frost alert.
