IV.) Controls/Menu Description:

.) Menu flow chart

2.) Description of the Device

3.) Description of the Control Buttons and Modes

There are four control buttons located on the face of the unit just below the

display

First button going from left to right is the (PRG button) this button is used to

enter the program setup menus by pressing and holding it down for 3

seconds

The PRG button has a plus sign (+) located right below the PRG on the face

The next button on the right of the (+PRG) button is the (-MAN) button

The (MAN) button can be quickly pressed while in the run mode operation to

quickly turn on output 1 on and off manually

There is also a minus sign (-) located underneath this button which means

that when the unit is in the program mode, this button can be quickly pressed

to go back to the previous screen or menu

The third button from the left is the (MAN2) which works just like the MAN

button except it controls the output 2 relay during run mode

The third button from the left also works as a double button (ESC), which is

used during the program mode to exit out of the menu or out of the program

mode and back to the run mode

The button on the far right is the (OK) button

The (OK) button can be used to scroll through the date, time, and year

setting during run mode operation by quickly pressing the button

k) The (Ok) button is also used as the enter button from entering the program

parameters in the program mode

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.

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
