MINIMUM HEAT/COOL SETPOINT DIFFERENCE - The Heat
and Cool setpoints will not be allowed to come any closer
to each other than the value set in Advanced Setup step
#7, on page 13. This minimum difference is enforced
during Auto changeover and Program On operation.
PROGRAMMABLE FAN - If the Programmable Fan timer is
set to a value other than 0, the fan will run for the
preprogrammed amount of time, page 14, step# 10.
The Programmable Fan timer will start the fan at the top
of each hour. The Programmable Fan may be active

DUAL SETPOINT BEHAVIOR - The adjustable setpoint range
is: 35 - 99 degrees in Fahrenheit and 7 - 35 degrees in
Centigrade. When in the modes Heat or Cool, this
adjustable range is unhampered.
When adjusting any Auto mode, including programming
time periods, the thermostat will not allow the Heat
setpoint to get closer to the Cool setpoint than the
value programmed as the minimum difference in
step 7, page 13.
When entering the Auto mode from Cool, the Heat and
Cool setpoints will remain spread apart by the amount
that they were adjusted, prior to entering Auto.
For example: If the Cool setpoint was set to 80 while
in the Cool mode and the Heat setpoint was adjusted to
70 while in the Heat mode, upon entering theAuto mode
the Heat and Cool setpoints would be 80 and 70. Both
setpoints would then move up and down together, (in this
example spread by 10 degrees), by pressing the up or
down buttons.
To move the Heat and Cool setpoints closer together,
enter the Cool or Heat mode by pressing the Mode button,
then adjust the setpoint(s) closer together. Heat is limited
to how close it can come to Cool by step 7, page 13.
