Can I use this timer to control any type of device?
The USAutomatic solar friendly timer is designed to be used with all USAutomatic products. The special solar friendly
design will not allow for use on all types of devices. The open collector output should only be connected to low
current (max 50 ma) applications. This allows for operation on most 12 volt dc devices.
Timer display is blank
If the timer display is blank connect power red wire (12 vdc) and black wire (ground)
If timer display continues to be blank press the reset button “R” for 1 second and release
Timer will not execute the program
Verify that the timer is in program mode – look just below the time and observe the mode timer is set in.
If “always off” is selected press the N button until PROG with the empty light bulb to the left is selected.
Timer is executing the program always
Verify that the timer is in program mode – look just below the time and observe the mode timer is set in. If “always
on” is selected press the N button until PROG with the empty light bulb to the left is selected.
Which PROG mode should the timer be set to?
The PROG mode has 2 settings (use the N button to toggle between modes)
1. PROG with empty light bulb to the left indicates ON state of timer
2. PROG with half full light bulb to the right indicates OFF state of timer
By toggling the mode with the N key you can temporarily override the event programmed. No matter which mode
the timer is left in the event programmed will execute as programmed in the next 24 hours.
Example: Timer is programmed to the ON state at 7:00 and OFF state at 19:00 and it is 12:00. The timer should be
executing the program and displaying the PROG with empty light bulb to the left. Pressing the N key until mode
changes to PROG and half full light bulb to the right will temporarily turn timer OFF. The timer will stay OFF until 7:00
cycles back around.
Menu contents:
To view menu items press the Y button and the menu will appear on the right side of the display
PROG – This mode is for setting the ON and OFF times of all events
DOWN – This mode will activate device connected when timer counts down to zero.
CLOCK- This mode is used to set the time date and time of the clock.
SUMMER – This mode is for daylight savings time the + or – can be used to toggle clock time 1 hour.
RANDOM – This mode will randomly activate the device connected to it.
How do I manually change timer to the always ON or always OFF mode?
When one of these modes are used the timer will not execute any programs.
Press the N button cycling the mode (indicator below time display) until “AlWAYS ON” or “ALWAYS OFF” appears.
Place back into program mode by pressing N button cycling the mode back to “PROG” with empty light bulb to left.
The timer only has 3 wires what are they used for?
Red wire: is supply voltage +12 vdc
Black wire: is supply voltage ground
Blue wire: is the signal wire: When timer is running program or in the always ON mode this wire will supply a
ground connection. Only connect to circuits that need a ground to activate the device.
Is this timer Solar Friendly?
YES, the current draw in standby or program mode is less than 1 ma. This meets the requirements of the Solar
Friendly Manufacturers Association.
Event programming conflicts with other event programming
In case you program ON and OFF times that overlap the earliest ON time and OFF time will be executed.

Can this timer be used to turn on and off devices such as keypads, Free exit sensors or other devices?
Yes, if you desire to control operational time of such devices connect the Relay N/O from the device to the blue wire
only. The device will only operate when the program is running or timer is in the always on mode. This disconnects
the device relay common thus disabling the device from operating what it is connected to. See illustration below.
The illustration below shows how to wire the 7 day timer so that it controls the functional time of the hard wired
device. The timer should be programmed with an ON time and OFF time corresponding to the time of the day the
device needs to be functional.
If you toggle the timer to the always ON mode the device will always work.
If you toggle the timer to the always OFF mode the device will not work.
If you toggle the timer to the PROG mode it will execute the events programmed.
The illustration below shows how to wire the 7 day timer directly to a gate or door. The timer should be programmed
with an ON time and OFF time corresponding to the time of the day the gate or door is to be held open. The close
function must be part of the gate or door control board. The timer only holds the gate or door open overriding any
automatic close function of the gate or door control board.
If you toggle the timer to the always ON mode the gate or door would always be open.
If you toggle the timer to the always OFF mode the gate or door will operate as if no timer is present.
If you toggle the timer to the PROG mode it will execute the events programmed.
