Temperature limiting can reduce
energy costs by limiting the lowest
temperature that can be set on
cooling and the highest tempera-
ture that can be set on heating.
Temperature limiting is controlled
by setting the first six auxiliary
switches.
The first three are used to select
cooling range limits and the next
three are used to select heating
range limits.
