6.2.1.3. Outside Temperature
Compensation
Stage 1 and 2 bandwidths can be adjusted
automatically as a function of outdoor tem-
perature compensation.
temperature decreases, stages 1 and 2 band-
widths increase gradually to compensate for
the change. The user specifi es the bandwidth
used in summer as well as the bandwidth used
in winter for both variable outputs of stages
1 and 2. The bandwidths can be adjusted
from 1 to 10°F (0.6 to 5.6°C). The winter's
bandwidth must be even or greater than the
summer's bandwidth.

The start temperature of a fan stage
must be greater value than its stop

Var1 & Var2 bandwidth — Set the number of
degrees required for variable fans to reach their
full speed in stages 1 and 2. If the "Outside
temperature compensation" function is used, set
these bandwidths separately for winter and for
summer (see sec. 4.5).
Start/Stop Temperatures
Note that the start temperature of a fan
stage is likely to change if the set point
changes or if the bandwidth changes
according to the outside temperature.
