SAFETY CONSIDERATIONS
Read and follow manufacturer instructions carefully. Follow all
local electrical codes during installation. All wiring must conform
to local and national electrical codes. Improper wiring or
installation may damage thermostat.
Recognize safety information. This is the safety- -alert symbol
When you see this symbol on the equipment and in the instruction
manual, 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

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
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
cooling.
INSTALLATION CONSIDERATIONS
A07109
AC Operation
For 24VAC operation, both the R and C wires must be connected
to the 24VAC power source. Batteries are not needed.
Battery Operation
When batteries are used, the common (C) connection is not needed,
PAGE
saving a wire, and eliminating 24VAC operation. The thermostat
1
continues to operate in the event of a power failure. Battery life is
expected to be one year. A "low battery" reminder tells the
1
homeowner when it is time to replace the batteries. When
1
connected without the common wire, the thermostat will not
1
operate without batteries. Continuous back- -lighting is not
available.
1
Both Battery and AC Operation
2
If both batteries and 24VAC operation are used (batteries installed
2
and the common wire connected), and indefinite clock operation
2
are provided, the battery will be used only during AC power loss,
3
extending battery life to nearly its shelf life.
A jumper has to be properly set for backlight operation. J2 should
4
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
to operate if J2 is not in the correct position or not connected.
However, the backlight will not operate.
.
Step 1 — Thermostat Location
Thermostat should be mounted:
S Approximately 5 ft (1.5m) from floor.
S Close to or in a frequently used room, preferably on an inside
partitioning wall.
S On a section of wall without pipes or duct work.

- Page 2 HP or PH controls 1 speed heat pump with 1 stage of aux heat. AC or PC controls 1 speed air conditioner with one stage of heat. Note that this option allows a HP thermostat to be converted to control an AC system.
- Page 3 Staging Timer If the thermostat is a heat pump model, it has 2- -stage heat capability. In normal operation there is a 15- -minute delay between the first and second stages of heat. The Y output will energize first, then 15 minutes later, W is allowed to come on if the thermostat determines it is not satisfying the demand.

When using batteries for power, we recommend you replace them with two AA alkaline batteries. They are in a compartment under the lid on top of the thermostat. You do not have to remove the thermostat from the wall to replace the batteries. Simply open the lid, lift out the batteries, and replace them like you would any other battery operated device. - Page 7 THERMOSTAT LIMITED WARRANTY FIVE- -YEAR LIMITED WARRANTY - - Bryant Heating and Cooling Systems (hereinafter referred to as “Company”) warrants this product to be free from defects in material and workmanship.
