Recovery with rotary heat exchangerThe capacity of the rotary heat exchanger is steplessly controlled via the modulated control of rotor speed.Free coolingIf the outdoor/intake temperature exceeded a settable limit (22 degrees) during the previous day, the fans will start to cool down the building during the night (settable time period with default values 00.00 …. 07.00) as long time as the outdoor temperature is within af settable interval (default 18 degrees ….. 10 degrees). The function is only active before and after time scheduled operation. All parameters can be set individually. Default stop conditions is when extract/room temperature goes below 18 degrees (settable value) or if outdoor temperature goes outside the allowed interval. After 1 hour the system will start up again if all start conditions are met. Optional room- and outdoor temperature sensors will improve performance of this function.Extended running - normal, reduced speed, high speed and stop
