4.Enter a setpoint temperature using the numeric, decimal point and sign keys. Numbers may be entered with a maximum of 1 decimal place. Pressing the sign <+/->key will toggle the value between positive and negative. Positive values will have no indication, negative values will show a minus (-) sign to the left of the temperature display.

5.Errors may be corrected by simply pressing <CLEAR/ENTRY> and re- keying the entry prior to pressing <ENTER>.

6.After the number is keyed in, press <ENTER> to commit the entry and store it as the new setpoint.

7.The controller will remain in the RUN mode if the rotary switch has not be changed and <START/STOP> has not been pressed.

Note: If the setpoint entered is not within the System Operating Range (See Section 3.5), an error message will be displayed and the setpoint will not be stored. If the requested setpoint is below the System Operating Range, the error will be preceded by a minus sign (-). Examples:

sor -sor

When this message is displayed, press <CLEAR/ENTRY> to return to setpoint entry mode.

TIP: It is not necessary to stop the controller from controlling the chamber or platform to change the setpoint. The setpoint may be changed at any time, even while the chamber or platform is being actively controlled.

5.3 Controlling to a Setpoint

The controller will start to control to the specified setpoint when <START/STOP> is pressed. The RUN LED will light to indicate the control process is active. A subsequent press of <START/STOP> will cause the controller to stop controlling and the RUN LED will be extinguished. Unless disabled through setup parameter F15, Blower Shut-off Mode (See Section 8.5), the chamber blowers will continue to run regardless of RUN status. If <START/STOP> is pressed before a setpoint has been set, the following error will be displayed:
