LCD DISPLAY

Due to the nature of the LCD display, when the timer is exposed to
extreme cold temperature, the LCD display may become dim or
faded. You may also experience slow response from the LCD
display. This, however, does not affect the operation of the timer.
For better viewing, bring the timer indoors to room temperature
and wait several minutes. You will be able to resume
programming and setup once the LCD display returns to it’s
normal state.

MOUNTING BRACKET

For safe and optimal performance, use the supplied mounting
bracket to hold the timer vertically and flush against the wall.
You will require your own tools and accessories (i.e. power
