Energy saving
Heat recovery mode: Reduce about
20% reduction of heating/cooling load
HRV unit will reclaim the energy in cooling/heating operation of air
conditioner. HRV will reduce the cooling/heating load and increase the
cooling/heating efciency.
Auto mode:
Reduce about 8% reduction of heating/
cooling load
Properly select the different operation mode can improve the efficiency.
When the cooling operation is required in winter, you'd better use the
bypass mode, refer to the below table:

By rerunning mode: Reduce about 2%
reduction of heating/ cooling load

finishing pre-running mode, HRV will turn into normal mode. Thus the
cooling/heating load will be reduced and reach the admired temp. quickly.
