Number of W7100 stages can be increased by six stages—four cool and two heat, or two cool and four heat, using W7101
Satellite Sequencer (except W7100E).
b
W7100D has single selectable modulating output—either heat or cool.
c
W7100D heating and cooling stages are not designed for use with the W7101 Satellite Sequencer.

cient of 4.8 ohms/degree F [8.6 ohms/degree C], resis-
tance of 3484 ohms at 77° F [25° C].
CONTROLLED STAGES: Resistor value (across termi-
nals 7 and 8) to determine number of on-off stages
controlled by W7100. Varies from 100 ohms for one
stage to 1000 ohms for 10 stages with W7101 (see
Table 2).
