If the controlling water temperature rises above this Setpoint,
the Heat Rejection or Cooling Stages begin to stage on. As the
temperature continues to rise above the Setpoint by the
Deadband amount, an additional stage is added. Each
additional stage can only activate if the temperature rises above
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
°
2 x 3
°
+ 79
°
= 85
°
before stage 3 can activate
