Degree Days Configuration

To calculate heating degree days, set the parameter HDD-01 = heating limit.

If you want to calculate degree days, set RMT-01 = room temperature setpoint

Heating Limits for Different Building Types

The better the thermal insulation, the lower the heating limit will be.

The following table shows the heating limits and the room temperatures for different building types.
