7.1.7 Relative Secondary (Cool) Gain r2G

 

The proportional band parameter ‘PB’ adjusts the proportional band for the heating output. Relative cool gain adjusts the cooling proportional band relative to the heating proportional band. If the rate of heating and rate of cooling are widely different it may be necessary to manually adjust Relative Cool Gain to achieve the optimum settings for the cooling proportional band. A nominal setting of around 4 is often used.

 

Note: This parameter is set automatically when Auto-tune is used.
