Both the supply and exhaust air fan speed will slowly decrease until the minimum
RPM is reached

After 10 seconds both fans will stop completely for four hours.

When the defrosting is done both fans will start at minimum RPM and increase
speed until the originally requested speed is reached.
If the outdoor temperature is ≤ -13 °C for more than 4 minutes 25 seconds and you do not
have a preheater installed, the unit will stop all operation for 30 minutes. This will happen
even with defrost mode activated.
After 30 minutes the unit will attempt to start up - activating the previous operating mode.
If however an electrical preheater is installed, this safety operation stop is automatically
disabled.
