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

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.

INTRODUCTION

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

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,

saving a wire, and eliminating 24VAC operation. The thermostat

continues to operate in the event of a power failure. Battery life is

expected to be one year. A “low battery” reminder tells the

homeowner when it is time to replace the batteries. When

connected without the common wire, the thermostat will not

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

to operate if J2 is not in the correct position or not connected.

However, the backlight will not operate.

INSTALLATION

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.
