■ TROUBLESHOOTING

PROBLEM: Days are flashing, pressing any key does nothing

except key turns output ON and OFF.

SOLUTION: Time of Day and Day of Week have not been set. See

“SETTING THE TIME”

NOTE: This is the condition after a reset. If the timer is found in this

condition after it has been installed, programmed and operating for a

while, it may indicate that electrical noise or voltage transients have dis-

rupted the microprocessor causing a loss of program information. Call 1-

800-272-1115 and request that a no-charge “Snubber Filter” be sent to

you to place across the input to the timer, which may solve the problem.

A second, but very unlikely cause of loss of program is a power fail-

ure with the backup battery low or dead. Check by disconnecting power

and monitoring how long the battery keeps the time of day in the display.

PROBLEM: Time of day was set while holding the key down,

but days are still flashing.

SOLUTION: Current day of week was not set while holding down

the key. See “SETTING THE TIME”

PROBLEM: It is 10AM and a ON program for 8AM was entered, but

the output is not ON. Display shows the and symbols.

SOLUTION: After programming, the timer does not “look back” to

determine if it should be ON. Press the key (temporary override)

to turn the output ON; appears in display. The timer will

assume automatic operation at the next programmed event.

PROBLEM: A program for 8AM Monday thru Friday was entered,

but it will not accept it and CH1

is flashing.

SOLUTION: The ON or OFF was not entered as part of the

program. ON or OFF must be selected.
