DUAL SETPOINT BEHAVIOR - The adjustable setpoint range

Centigrade. When in the modes Heat or Cool, this
adjustable range is unhampered.

time periods, the thermostat will not

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 the Auto 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.
