Recognize safety information. This is the safety- -alert symbol
When you see this symbol on the unit and in the instructions or
manuals, be alert to the potential for personal injury.
Understand the signal words DANGER, WARNING, and
CAUTION. These words are used with the safety- -alert symbol.
DANGER identifies the most serious hazards which will result in
severe personal injury or death. WARNING signifies a hazard
which could result in personal injury or death. CAUTION is used
to identify unsafe practices which may result in minor personal
injury or product and property damage. NOTE is used to highlight
suggestions which will result in enhanced installation, reliability, or
operation.
There are two Legacy Line- -RNC Series programmable thermostat
models, one for AC applications and one for HP applications. Both
are dual powered, operating from either 24VAC or two alkaline
AA batteries. Configuration and program schedules are stored in
A07109
non- -volatile memory, preserving this information during power
loss and battery removal. Features include simplified 5/2
programming, large backlit display, and modern styling.
The AC model provides one stage of heating and one stage of
cooling.
The HP model provides two stages of heating and one stage of
PAGE
cooling.

INSTALLATION CONSIDERATIONS

AC Operation
1
For 24VAC operation, both the R and C wires must be connected
1
to the 24VAC power source. Batteries are not needed.
Battery Operation
1
2
When batteries are used, the common (C) connection is not needed,
saving a wire, and eliminating 24VAC operation. The thermostat
2
continues to operate in the event of a power failure. Battery life is
2
expected to be one year. A "low battery" reminder tells the
3
homeowner when it is time to replace the batteries. When
connected without the common wire, the thermostat will not
4
operate without batteries. Continuous back- -lighting is not
available.
Both Battery and AC Operation
If both batteries and 24VAC operation are used (batteries installed
and the common wire connected), and indefinite clock operation
are provided, the battery will be used only during AC power loss,
extending battery life to nearly its shelf life.
A jumper has to be properly set for backlight operation. J2 should
be set in the "AC" position when the thermostat is operated from
24VAC. J2 should be set in the "BAT" position when the
thermostat is operated from batteries. The thermostat will continue
