IGNORE TIME
(DTT)
The deviation temperature ignore time is the time from when
a deviation from setpoint is sensed until it is displayed. The
deviation from setpoint occurs when the actual temperature of
the fluid is some value away from the setpoint (value is set by
dt).
The deviation temperature ignore time range is 0-600 sec-
onds, the default is 300 seconds and should be sufficient for
most applications.

This feature ensures that there is adequate flow through the
evaporator before allowing the compressor to start. The value
set in this parameter is the time after start-up. The control will
wait for the flow switch to be made before shutting down. If
shut down occurs FAL will flash on the control and request
the unit to be reset. Proceed to troubleshooting section if this
occurs. The range is 0-20 seconds, the default value is 10 sec-
onds and should be adequate for most applications.
