Changing the Setpoint

To change the controller setpoint, turn the unit On/Off switch ON. With the standard LCD message display showing on the controller (i.e. setpoint temperature):

  1. Press the SETPOINT key. The DATA menu appears with the cursor flashing in the “TEMP SETP” line.

  2. Press the F4 key. An Enter Arrow appears in the menu line and the current setpoint disappears.

  3. Enter (type) the new setpoint in the LCD display using the general purpose keypad. To enter a minus setpoint, press the EXIT (±) key first. The cursor moves to the right of the screen as each key entry is acknowledged and displayed.

    Note Always check that the setpoint entered in the LCD display is correct before proceeding.

  4. Press and hold the F4 key until the cursor stops flashing. The new setpoint is recorded in the controller and appears briefly in the LED display.

    Note When the setpoint appears in the LED display, both the Return and Supply LEDs are lit.
    Note If the F4 key is not pressed within 30 seconds, the controller will default (return) to the previous setpoint. If this occurs, repeat steps 1 through 4.

  5. Controller returns to the standard LED Display (shows return temperature) within 5 seconds and the standard LCD display (showing new setpoint) within 60 seconds.
