SETTING THE SPAN
The SPAN setting mode in the SYSTEM SETTINGS MENU allows you
to adjust the system ON/OFF cycle rate. The default setting is 2F. The
system cycles ON or OFF when the temperature is within 2°F (1°C) above
and below the set temperature. The span setting can be adjusted if your
system is cycling too fast or too
slowly.
Setting a higher SPAN number
increases your cycle time by
allowing the system to run longer;
a lower number will decrease your
cycle time by causing the system
to run for a shorter length of time.
With the STAGE TIMER (Option
10) set to 0, stages 2 and 3 will
be controlled by the SPAN setting
only. If the stage timer is set to 30,
the system will turn on the next
stage based on the SPAN setting
or 30 minutes, which ever comes
first.
Span settings remain the same for
Heating and Cooling.
