Note
The high power limit controls the percentage of full power
that is sent out to the heaters. The optimum setting
depends on the set point temperature and on the heated
device. If this high power limit is set too high and the set
point is close to the high temperature limit of the heated
device, the heater(s) may heat too quickly and burn out.
If the high power limit is set too low, the heated device
may heat too slowl
and may not reach the set point.
Adjust this setting as needed from the recommended
initial settings to achieve the desired heating profile.
