There are two Base 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,
PAGE
saving a wire, and eliminating 24VAC operation. The thermostat
1
continues to operate in the event of a power failure. Battery life is
1
expected to be one year. A "low battery" reminder tells the
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.
