Temperature Controller Internal Switch Factory
Settings
Each temperature controller has internal switches to
control some of its operational characteristics. The
switches are only accessible if you remove the control-
ler from the electrical control panel. The factory set-
tings should satisfy most application needs.
For information about changing the settings, see the
temperature controller instruction sheet, included in the
electrical control panel documentation.
The factory settings are (Fig. 5):
1. Start with the temperature control in display mode.
2. Press the change mode key (4) once. The mode
indicator (3) changes to SET.
3. Using the down (5) and up (6) arrow keys, set the
desired set point temperature.
4. When you have set the desired temperature, push
the mode key (4) again. The mode changes to set
alarm mode.
5. To set the alarm, go to the next section, Setting
Alarm Temperatures. If you have finished setting
the temperature control, push the change mode
key (4) again. This returns you to the display
mode.
