Pressing the UP (Black) button replaces the date with the day of week, this returns to the date when
the button is released.
Pressing the DOWN (Grey) button changes the state of the output relay. This will remain in
operation until the next on / off time is reached, or the DOWN button is pressed again.
When one of the preset on times is reached the relay will operate. This will remain on until the off
time is reached or the relay output is overridden by pressing the DOWN button.

PROGRAMMING
The TC310 is programmed using only 3 buttons. Each button has the following function.
PROG (Yellow) used to enter program mode and to step through program items.

program mode.
DOWN (Grey) overrides the relay output On to Off or vice versa during normal operation. Decrements the
flashing item in program mode.
If during program mode no button is pressed for 1 minute the clock automatically reverts to the time display.
