result of the PID modifier.Press Start/Stop key
to stop operation
during unit operation, and the unit enters into standby mode.
4.4 Start/Stop pump
The pump indicator is off state when pump does not work.press pump
key
to start ,the pump indicator lights on.During pump is working ,
press
can turn off the pump.
In the unit working state, it is invalid to stop the pump by pressing
the Pump key
.
4.5 PID Adjustment
When medium circulator works under different temperatures, the control
parameters are slightly different if cooling power is different. When
connecting with different loading units, the control parameters are usually
different PID parameters can be adjusted via circulator for much more
precise temperature control.
Adjustment process
：
First set the target temperature, once
temperature achieved around, Long press Enter key
more than 5
seconds, main display shows actual temperature,the auxiliary display
shows the adjusting target and adjusting state alternatively. At this
moment, users need not do any operation. When adjustment finished, the
system will quit automatically and enter into operating state. This
operation is only recommend the users who are familiar with PID control
principle.
