Temperature limiting can reduce energy costs
by limiting the lowest temperature that can be
set for cooling and the highest temperature that
can be set for 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.
