4.) Economical Mode
The 7DT-2CH is shipped with a pre-programmed real time in economical mode.
The unit uses battery memory which allows the unit to keep data stored even when the
unit does not have supply voltage on terminals A1 and A2. This device is capable of
viewing the time with no supply voltage present by pressing any of the control buttons for
two seconds. The 7DT-2CH display will illuminate and display pre-set time. When
supply voltage is connected to terminals A1 and A2 the unit will continuously display the
timing switch’s status until supply voltage is removed.
5.) Illumination of Display
The 7DT-2CH illuminates whenever one of the control buttons are pressed and
remains that way for 10 seconds after the last button was pressed. To have the LCD
display stay illuminated permanently. The three control buttons (ESC/MAN2), (-MAN1),
and the (OK) must be pressed and held down together from 3 second. The display will
flicker once to show that the permanent illuminated feature has been entered. The same
three buttons again must be pressed and held down simultaneously to turn the display
illumination feature off. The display will flicker and than turn the display light off.
6.) Reset the Time, Date, and Year
The 7DT-2CH has a small hidden reset button located on the front left side of the
unit (this can be seen on page 4 under
description of the device
). By using a pin with a
diameter no bigger than 2 mm you can press this small hidden reset button (when
pressed the screen will go blank). Upon releasing the button the display will show SHT-1
for 3 seconds (This is the version of firmware used) and go to starting mode. The reset
will delete the real time, the set time of the pulse/cycle mode and all temporary functions.
Reset will keep the set programs.
7.) Reset all the Programs
All storied programs can easily be erased by pressing down and holding both
(+PRG) and (OK) buttons simultaneously for a few seconds. The word ALL will be
displayed once the two control buttons have been held down. Now just push the (OK)
button and the unit will delete all existing programs
