Follow alllocal electrical codes during installation. All wiring must conformto local and national electrical codes. Improper wiring orinstallation may damage thermostat.Recognize safety information. This is the safety--alert symbol .When you see this symbol on the equipment and in the instructionmanual, be alert to the potential for personal injury.Understand the signal words DANGER, WARNING, andCAUTION. These words are used with the safety--alert symbol.DANGER identifies the most serious hazards which will result insevere personal injury or death. WARNING signifies a hazardwhich could result in personal injury or death. CAUTION is usedto identify unsafe practices which may result in minor personalinjury or product and property damage. NOTE is used to highlightsuggestions which will result in enhanced installation, reliability, oroperation.INTRODUCTIONThere are two Base Series programmable thermostat models, onefor AC applications and one for HP applications. Both are dualpowered, operating from either 24VAC or two alkaline AAbatteries. Configuration and program schedules are stored innon--volatile memory, preserving this information during powerloss and battery removal. Features include simplified 5/2programming, large backlit display, and modern styling.The AC model provides one stage of heating and one stage ofcooling.The HP model provides two stages of heating and one stage ofcooling.INSTALLATION CONSIDERATIONSAC OperationFor 24VAC operation, both the R and C wires must be connectedto the 24VAC power source. Batteries are not needed.Battery OperationWhen batteries are used, the common (C) connection is not needed,saving a wire, and eliminating 24VAC operation. The thermostatcontinues to operate in the event of a power failure. Battery life isexpected to be one year. A “low battery” reminder tells thehomeowner when it is time to replace the batteries. Whenconnected without the common wire, the thermostat will notoperate without batteries. Continuous back--lighting is notavailable.Both Battery and AC OperationIf both batteries and 24VAC operation are used (batteries installedand the common wire connected), and indefinite clock operationare 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 shouldbe set in the “AC” position when the thermostat is operated from24VAC. J2 should be set in the “BAT” position when thethermostat is operated from batteries. The thermostat will continueto operate if J2 is not in the correct position or not connected.However, the backlight will not operate.INSTALLATIONStep 1 — Thermostat LocationThermostat should be mounted:S Approximately 5 ft (1.5m) from floor.S Close to or in a frequently used room, preferably on an insidepartitioning wall.S On a section of wall without pipes or duct work.
