4 Ready Delay Time
Description:
The amount of time that will elapse after all of the components have reached
their setpoint temperatures before the Ready LED turns on. The ready delay
time only functions when the temperature of the tank, at the time the melter is
turned on, is more than 27 °C (50 °F) or more below its setpoint temperature.
The ready delay time begins when all components are within 3 °C (5 °F) of their
respective setpoint temperature.

The ready delay allows the tank additional time to heat up before the pump
starts up.

right display at the end of every automatic scan cycle. Below one minute, the
time remaining appears in seconds.
Pressing the Heater key twice overrides the ready delay time. BUT
CAUTION: Always allow at least a 30 minute ready delay to prevent the pump
from being damaged when it is switched on.
