Outside air temperature frost protection

At low outside air temperatures, below the limit OAT-01, the pump will run continuously, regardless of the plant mode value.

This protection function stops as soon as the the filtered outside air temperature is above OAT-01 + 1K.

If this function is active, the output "ERCFreezeProt" will be switched on.
