Hold Percentage
The Hold Percentage provides just enough power to the heating pads to compensate for heat loss, clamping
the temperature at the set point. The temperature hold heating percentage is used when the temperature is
within +/- 1 degree of the Set Point temperature.
The actual Hold Percentage is dynamically adjusted according to the measured temperature. When the
temperature settles below the Set Point, the adjusted percentage is incremented. When the temperatrue
settles above the Set Point, the adjusted percentage is decremented. These small changes in power will
slowly nudge the temperature towards the Set Point, while minimizing over/under shooting.
The Hold Percentage setting remains unaffected by the adjusted setting. The adjusted setting remains in
affect until the heater control box is powered off. A good starting value is 10 Percent.
