Series 8900SH Control Panel Operation And Installation Manual If the outside temperature continues to drop, then the calculated Reset Ratio (code 23) will be activated. More heat will be required to maintain the building temperature. To determine how much more, the control panel monitors (when in Automatic mode) the outdoor air temperature, the current Return Water Line temperature, the design return water temperature, and the design outdoor temperature. It then determines the R
