If the controlling water temperature drops below this Setpoint, the Heat Addition or Boilers begin to stage on. As the temperature continues to drop below the Setpoint by the Deadband amount, an additional stage is added. Each additional stage can only activate if the temperature drops below the Setpoint by the number of active stages times the deadband value.
Example: There are 2 stages on, a 3° deadband and the setpoint is 79°
79° - 2 x 3° = 73° before stage 3 can activate
