change to C° mode, slide the switch to C° and press the reset
button on front of the thermostat with a paper clip.
NOTE: Unless the reset button is pressed, the thermostat
will not change temperature mode.
■ 12 Hr. / 24 Hr. selector – Switch 6
Your thermostat is set for normal 12 hour (AM / PM) time

the thermostat, and will automatically change the current time
display and all program times in memory.

the set temperature. If you require slower temperature cycles in
Heat mode, you can select +2°F / – 1°F by sliding the switch to
the ALT position. This may be necessary if your heating system
cycles too rapidly.
