The following example shows how heating behaves as Ta starts to fall:
- When Ta falls below +10 °C, heating is enabled.
- Heating keeps Th > +4 °C until Ta < -11 °C.
- Between -11 ... -65 °C, Th is approximately 15 °C warmer
than Ta.
When the heating function is disabled the heating is off in all conditions,
see
Supervisor Message on page 101 .
NOTE Snow accumulation may cause a temporary wind measurement
problem even when the heating is enabled.
